Effect of increased basalt fibre dosage on hybrid basalt fibre reinforced concrete's strength properties

Natural, eco-friendly fibers are increasingly being used as reinforcement in the creation of lightweight, low-effort polymer composites on a global scale. Because it is intelligent and has unique properties above glass fibers (GF), basalt fiber (BF) is one such material of interest that is currently in widespread use. Among these composites' clear advantages are their high specific mechanic properties, biodegradability, and non-grating nature. In this paper, basalt fibers used as reinforcement for composites are surveyed. The study also addresses how concrete's strength is affected by curing. In addition to this, an attempt is made to highlight the growing trend in research dissemination and activity in the area of basalt fibers. Further segments talk about the improvement in mechanical, warm and synthetic safe properties accomplished for applications in specific enterprises. The results of this study reveal that the optimum value of strength at 28th day of curing is obtained for a mix made with 5% of chopped basalt fiber 50% 6mm Long BF and 50% 12mm Long BF.

Sustainable Optimization of Concrete Strength Properties using Artificial Neural Networks: A Focus on Mechanical Performance

Abstract In this study, a comprehensive dataset comprising 358 data points was collected from the literature, focusing on the compressive strength, split tensile strength, and modulus of elasticity of concrete incorporating recycled concrete aggregate. An Artificial Neural Network was employed as the primary machine learning algorithm to predict these mechanical properties. K-fold cross validation was utilized to validate the model’s reliability, while sensitivity analysis was performed to identify the most influential input parameters among the independent variables. The model demonstrated strong performance during training, achieving R2 values of 0.97 for compressive strength, 0.98 for split tensile strength, and 0.99 for modulus of elasticity with corresponding RMSE values of 2.55, 3.85, and 0.37, respectively. The MAE and MAPE values during training were 0.68 and 0.03 for compressive strength, 0.71 and 0.03 for split tensile strength, and 0.67 for modulus of elasticity, with RMSE values of 8.57, 5.03 and 3.83, respectively. Testing results revealed R2 values of 0.75 for compressive strength, 0.78 for split tensile strength, and 0.78 for modulus of elasticity, with RMSE values of 8.57, 5.03, and 3.83, respectively. The sensitivity analysis indicated that the cement percentage and water-to-cement ratio were the most significant parameters influencing concrete strength.

Seawater-mixed concretes containing supplementary cementitious materials: compressive strength, e-modulus, electrical resistivity, and life cycle assessment

Water and concrete are the materials humans consume the most on earth. By 2040, several countries are expected to face extreme water stress and the need for significant growth in their infrastructure simultaneously. Water is a fundamental ingredient for concrete production, and the need for infrastructure growth can further increase the water demand for concrete production and thus affect these regions facing water scarcity. Including supplementary cementitious materials (SCMs), non-metallic fibres, and coated/polymer reinforcements can increase the feasibility of producing concrete with seawater (SW). There is a lack of information on the long-term strength and durability properties of SW-mixed concretes (SWC) produced with SCMs. This paper optimises binder compositions with CEM I, fly ash, ground granulated blast furnace slag (slag), and metakaolin suitable for adapting SWC based on performance indicators. Binary and ternary blended concretes of similar binder content (360 kg/m3) and w/b (0.45) were designed and cast with the SCMs mentioned above. Compressive strength, surface resistivity, and accelerated carbonation tests were conducted on the concrete produced with freshwater (FW) and seawater (SW). SWC produced with 30% slag and 15% metakaolin had higher electrical resistivity and an improvement in compressive strength (up to 30%) than other combinations used for producing SWC. Life cycle assessment identified that the concretes produced with fly ash, and ternary combination of fly ash and metakaolin had the least water depletion potential (WDP) compared to other SW-mixed concretes. Also, the replacement of FW by SW reduces the WDP up to 50%.

An effect of nano alumina and nano titanium di oxide with polypropylene fiber on the concrete: mechanical and durability study

For a long time, researchers have worked to improve the qualities of cement-based mixes. Because of their small size, strong reactivity, and huge surface area, nanoparticles are becoming more and more regarded as one of the greatest substitutes for cement because of their capacity to increase durability and strength. This work presents the results of an experimental investigation into the strength and durability properties of fiber-reinforced concretes with polypropylene (PP) fibers added to the concrete by volume and nano Al2O3 and nano TiO2 are used as partial substitutes for cement. Nano Al2O3 and nano TiO2 particles used ranged in size from 30 to 300 nm. The specimens were cast using cement blended nano Al2O3 and nano TiO2 percentages of 1%, 2%, 3%, and 4% by weight of cement. M55 grade concrete was employed for the casting process. The addition of PP fibers to the concrete was 0.5% by volume. The specimens underwent a battery of mechanical tests, including microstructural testing, compression testing, split tensile strength testing, and rupture modulus testing. Furthermore, tests for durability factors such as porosity, sorptivity, and degradation were conducted, and the findings are presented. By comparing the outcomes, it was shown that the inclusion of 0.5% PP fibers and 2% nano Al2O3 or nano TiO2 improved the mechanical qualities, but a decrease followed this in strength. The findings demonstrated that 2% nano Al2O3 combined with 0.5% PP fiber had a greater mechanical strength than 2% nano TiO2.

Characterization of recycled aggregates to obtain concretes for common application

Abstract. The article is devoted to the study of possibility to use demolition wastes as an aggregate to create new effective concrete constructions. It had been shown that artificial aggregates from demolition wastes, especially from military origin, are very various and complicated in their composition. All demolition wastes are characterized by weak and damage structure. There are a lot of damages and cracks are present in the aggregates, lowering their service properties and properties of concretes on their basis. Moreover, such aggregates appeared from the war reasons also are containing a lot of additional problems such as rests of organic compounds, unburned particles form the fire and explosion, etc. It was shown that such kind of demolition wastes contain a lot of fine particles, influencing in a bad way on water consumption of the concrete mix. Also powder-like particles influence bad on service properties of concrete as well as on water to cement ratio in the concrete mix. However, it was proved that beside of negative influence of aggregates from demolition wastes on concrete properties, it is still possible to obtain concrete mixes and concretes on their bases able to be used as a common concrete. The best results are obtained using slag alkali activated cement. Compressive strength up to 32 MPa at 28 days is comparable to compressive strength of the control composition using OPC and traditional granite aggregate – 34 MPa at the age of 28 days of normal hardening. Use of slag OPC and recycled aggregates leads to the low compressive strength – up to 24 MPa at the age of 28 days. Also, it should be mentioned that all concretes under study were characterized by low flexural strength, proving necessarity to provide further mix design to increase strength properties of concrete on recycled aggregates basis.

The effect of travertine waste on the strength and insulation properties of foam concrete

Abstract Incorporating waste additives into foam concrete mixtures is a promising route to develop environmentally-friendly concrete production with tailored thermos-mechanical properties. In this paper, the effects of various fabrication parameters of foam concrete, including the type of waste additive, water/binder ratio, density of mixture, and incorporation of glass fibers were investigated. Foam concrete samples were fabricated using fly ash and travertine wastes, and the variations in their flexural strength, compressive strength, and thermal conductivity using various concrete mixture designs were measured. The obtained results show that foam concrete with fly ash additive tends to have higher compressive strength and thermal conductivity than foam concrete with travertine waste. However, the latter exhibits better thermal insulation properties, which tend to improve by adding glass fibers. This work defines the outlines for exploring the use of harmful wastes in fabricating foam concrete. It offers guidelines for developing improved foam concrete mixtures with tailored thermos-mechanical properties.

River Sand Replacement with Sustainable Sand in Design Mix Concrete for the Construction Industry

The present study prepared four sustainable design mixes of concrete using desert sand, modified recycled sand, and supplementary cementitious material silica fume to replace cement. The design mix concrete was prepared using the absolute volume method of a design strength (f´c) and target strength (f´cr)of 30 MPa and 38 MPa, respectively. The analysis of results showed that the four sustainable design mix concrete successfully passed the strength criterion set by the ACI 318-19 building code. The resulting pattern shows an increment in the mechanical and durability properties compared to the reference mix when (50% desert sand + 50% recycled crushed sand) is combined with 5-12.5% silica fume. The optimum result was achieved when the optimized, sustainable sand ratio (50% desert sand + 50% recycled crushed sand) was combined with 10% silica fume. It can be concluded that the prepared concrete has excellent results in terms of concrete strength and durability properties. Furthermore, this study shows that 100% of natural sand and 10% of cement can be saved using the optimal proposed concrete design mix. This study would have explored sustainability in the Saudi region by utilizing a vast percentage of vacant desert sand in concrete manufacturing. Doi: 10.28991/CEJ-2025-011-01-012 Full Text: PDF

Role of calcination process of natural colemanite powder on compressive strength property of concrete.

The use of boron minerals as an additive is important in terms of reducing CO2 emissions and providing input to the economy. Sustainable natural colemanite was subjected to calcination at 550°C in order to concentrate the amount of B2O3. For the characterization of calcined mineral, XRD, TGA/DTA, and B2O3 component tests were carried out. It was observed that the structure of natural colemanite changed, and the B2O3 value heightened by 11%. Then, natural and calcined minerals were added to the concrete mixture in proportions of 1.25%, 2.5%, 5%, 7.5%, 10%, 12.5%, and 15% by weight. Ultrasonic pulse velocity, Schmidt hardness, and compressive strength tests were fulfilled. In the samples with natural additives, the lowest compressive strength was 32MPa for the reference sample, whereas the highest strength was 44MPa for the 10% natural colemanite sample. In other words, the compressive strength increased by 39%. In the samples with calcined additives, the highest compressive strength was 30MPa for the 2.5% calcined colemanite sample; that is, it improved by 24%. It is realized that the cement can be saved since high strength can be obtained in concrete with natural and calcined colemanite additives.

Carbonation and Compressive Strength Properties of Electric Power Utility Tunnel Concrete Exposed to a Carbon Dioxide Environment

Recently, the service lives of electric power utility tunnels have been increasing rapidly; however, inspection and maintenance tasks are difficult, and the economic loss owing to the end of tunnels’ lifespans is substantial. Moreover, electric power utility tunnels are exposed to high carbon dioxide. Because their interiors are sealed environments, the tunnels are significantly affected by carbon dioxide. Carbon dioxide can cause concrete carbonation, which can lead to a decline in the performance of electric power utility tunnels. In this study, the carbonation characteristics of concrete were analyzed, and the effect of carbonation on the mechanical performance was evaluated.

Effect of multi-scale hybrid fiber reinforcement on mechanical properties of ultra-high performance concrete

An experimental investigation was conducted on the effect of multi-scale hybrid fiber reinforcement incorporating steel fiber and wollastonite fiber on mechanical properties (i.e. compressive strength, splitting tensile strength, flexural toughness and direct tensile properties) of ultra-high performance concrete (UHPC). The results indicate that, compared with macro-fiber, hybrid steel fiber composed of macro-fiber and meso-fiber improves the strength and toughness of UHPC significantly. The higher the dosage of meso-fiber, the better the effect of hybrid steel fiber. Meanwhile, longer meso-fiber provides a better performance in terms of interfacial bonding strength between the fiber and the matrix of UHPC, leading to an increase in the anti-cracking effect of hybrid steel fiber, and hence the improvement in the splitting tensile strength and flexural toughness of UHPC. Moreover, adding wollastonite fiber as micro-fiber is efficient to enhance the mechanical properties of UHPC incorporating with hybrid steel fiber. It may be related to the respective anti-cracking effect of three types of fiber and their synergistic snubbing effect, as well as the filling effect of wollastonite fiber and the chemical bonding effect caused by the reaction between wollastonite fiber and Ca(OH)2 in the paste.

Experimental and Statistical Assessment of the Interaction of Ether and Naphthalene-based Superplasticizers with Concrete

Background: The significant concerns surrounding the interaction between cement and superplasticizers have led to several challenges in the performance of concrete in realworld applications. This study investigates the interaction between different types of cement and superplasticizers and presents findings on their compatibility. Additionally, various interactions between cement and superplasticizers are utilized to assess the strength and durability properties of concrete. Methods: Three distinct types of superplasticizers were utilized: sulfonated naphthalene (SNF), polycarboxylic ether (PCE), and polymeric ether (PME) based superplasticizers, in combination with Ordinary Portland Cement (OPC) and Portland Pozzolana Cement (PPC). Multiple concrete mixes with varying addition times of these superplasticizers were prepared and evaluated for their fresh and hardened concrete characteristics, including workability, strength, and sorptivity, among others. Moreover, statistical analyses concerning different combinations of superplasticizers and cement, as well as varying addition times, were conducted to assess their respective impacts on concrete qualities. Results: The findings of the hypothesis testing indicated a substantial correlation between the delayed addition time of PPC mixes and variables, such as compressive strength and workability, with correlation coefficients ranging from 0.95 to 0.98. Conversely, the correlation between these variables and OPC mixes was not found to be entirely significant (r; 0.85-0.89). Discussion: The established relationship indicated an improvement in the properties of fresh concrete due to enhanced compatibility between different superplasticizers and cement, potentially aiding in the selection of optimal superplasticizer-cement combinations and addition times for superplasticizers. Conclusion: In the present study, numerous interactions between cement and superplasticizer are utilized to assess the strength and durability characteristics of the concrete.

Strength properties of concrete containing palm bunch ash–calcined anthill clay

AbstractThis study evaluated the strength properties of concrete produced with palm bunch ash–calcined anthill clay (PBA-CAC) as pozzolans. Two groups of palm bunch ashes were produced: ashes generated by burning only palm bunches (PBA) and ashes obtained by blending palm bunches and anthill clay at elevated temperatures (PBA-CAC). The PBA and PBA-CAC satisfied the requirements of Class C pozzolans. The concrete constituents were batched by mass, and the cement–fine aggregate–coarse aggregate ratio was 1:2:4. The cement content was partially substituted with PBA and PBA-CAC at 5%, 10%, 15%, 20%, and 25%, with the 0% specimen serving as the control. The concrete cubes were cured for 7, 14, 28, 56, and 90 days, whereas the concrete cylinders and beams were cured for 7, 28, 56, and 90 days. The 28th day strength values of the control specimens exceeded those of the PBA and PBA-CAC concrete specimens. By the 90th day of curing, the strength values of the specimens produced with 5% PBA and 5% PBA-CAC exceeded those of the control specimen. The PBA-CAC specimens generally had higher values of compressive strength, splitting tensile strength, and flexural strength than PBA specimens containing the same amount of pozzolan.

ОРГАНОМИНЕРАЛЬНЫЙ МОДИФИКАТОР НА ОСНОВЕ ШЛАМОВОЙ ВОДЫ ДЛЯ ПОЛУЧЕНИЯ ВЫСОКОПРОЧНЫХ САМОУПЛОТНЯЮЩИХСЯ БЕТОНОВ

The production of concrete mix is inevitably associated with the formation of sludge water, which has an impact on the environ-ment. The technology of recycling concrete mix allows you to use not only slurry water from the production of ready-mixed con-crete, but also to obtain a highly dispersed organomineral modifier (OMD) based on dehydrated sludge, obtained by fine grind-ing in a ball mill. A modifier was obtained by grinding in a ball mill for 2.5 hours with a specific surface area of 15657 cm2/g. The introduction of a dry polycarboxylate plasticizer in an amount of 0.025% made it possible to reduce the grinding time in the mill to 1 hour and obtain a specific surface area equal to 16227 cm2/g. The chemical composition of the organomineral modifier and the basic properties of cement paste in the presence of OMD are investigated. An increase in the normal density of the cement paste by 2.4%, an acceleration of the setting time and an increase in strength in the initial hardening periods were found. It is shown that the introduction of slurry water with mixing water in an amount of 5% into the concrete mixture does not lead to a decrease in strength parameters. The introduction of OMD based on slurry water in an amount of 10% does not adversely affect the technological properties and slightly increases the strength of concrete at the age of 28 days. The resulting modifier, partici-pating in the resource-saving cycle and possessing such important characteristics, will serve as an alternative to the use of other mineral additives used in the production of self-sealing concretes, will reduce the consumption of raw materials, and the selec-tion of its optimal content will affect changes in the technological and strength properties of concretes.

Performance and mechanism of the structure formation and physical-mechanical properties of concrete by modification with nanodiamonds

Nanomodifying additives in the building materials production is a relevant and widely studied topic in current building materials science. Nanodiamonds are used in various fields of science and technology. However, they were not used as a modifying additive in the production of building composite materials. The purpose of this study is to investigate the mechanism of interaction of chemically pure cavitation synthesis nanodiamonds (КНА-НС) with cement concrete on the structure formation and mechanical properties of fresh and hardened concrete. These KHA-HC nanodiamonds are carbon sp3 hybridized nanoparticles with a diamond-like structure and a particle size in a cross section of not more than 3 nm, shaped close to spherical and a clear mono modal distribution throughout the entire fractional composition, with a maximum of 1 nm to 3 nm. During the research, the initial components were selected, the compatibility of these components was checked, including the formation of test samples, the properties of fresh concrete, the density of hardened concrete, compressive and flexural strength at various ages of hardening (2, 7, 14 and 28 days) were studied using standard methods, and X-ray diffraction and scanning electron microscopy of concrete were also carried out. It has been established that the addition of KHA-HC accelerates the process of concrete strength gain. The greatest effect was recorded for concrete aged 2 days. With an optimal KHA-HC content of 0.4 %, the increases in compressive and flexural strength were 28.6 % and 26.1 %, respectively. The addition of KHA-HC in all considered ranges from 0.1 % to 1.0 % has a positive effect on the strength properties of concrete. The most effective dosage is 0.4 %. The increases in compressive and flexural strength of concrete at an age of 28 days were 15.1 % and 15.7 %, respectively. Nanomodification of concrete with the KHA-HC additive does not affect the phase composition of concrete. The effect of “self-reinforcement of cement matrix” put forward in this study is confirmed by images of the microstructure of the cement matrix with a large accumulation of calcium hydrosilicate zones.

Mechanical performance and co2 footprint analysis: recycled aggregate polypropylene geopolymer concrete compared with conventional concrete

Abstract Geopolymer concrete (GPC) has gained significant awareness in recent years as an eco-friendly alternative to conventional concrete due to its lower CO2 emissions and utilization of industrial waste materials. The cementitious material fly ash (FA), GGBS, silica fume (SF) with incorporation of polypropylene fiber (PF), recycled aggregates (RA) further promote the strength properties of geopolymer concrete, particularly in terms of ductility and crack resistance. Exploratory tests been conducted to assess the effects of various parameters including activator type, curing conditions, fiber content, and aggregate characteristics on the mechanical behaviour and CO2 emissions of geopolymer concrete (GPC). The mechanical performance aspects like as compressive strength(45.7Mpa), flexural strength(4.78Mpa), and split tensile strength(4.12Mpa) were attain by optimum mix design GPC-FG where cement substituted with ratio of FA:GGBS:SF - 40:50:10 and compressive strength(50.4Mpa), flexural strength(5.51Mpa) and split tensile strength(4.99Mpa) were attain by optimum mix design of Polypropylene based GPC-FGP where cement substituted with ratio of FA:GGBS:SF:PF - 40:49:10:1. The optimal mix design GPC-FG and GPC-FGP are compared there is raise in compressive strength of 9.325%, flexural strength of 13.241%,split tensile strength 17.434% of GPC-FGP, along with CO2 of polypropylene fiber-based geopolymer concrete with recycled aggregates as shown 60.01% reduction of CO2 when compared with traditional concrete. The results demonstrate the potential of geopolymer concrete to achieve comparable or superior mechanical performance while significantly reducing CO2 emissions compared to conventional concrete. This research adds to sustainable construction knowledge by showcasing geopolymer concrete’s environmental benefits, mechanical strength, and potential applications in the industry and infrastructure development.

Effect of cenospheres on the proprieties of plain concrete exposed to elevated temperature

AbstractThe main objective of the study was to determine the effect of the use of cenospheres for C30/37 class concretes used in construction and road construction. As part of the research, four concrete mixtures were designed: three with the addition of cenospheres and one reference mixture, without the additive. In the three modified mixtures, 20, 40 and 60% of fine aggregate were replaced by cenospheres, respectively. Selected features of the mixtures were determined—consistency and density, as well as the strength properties of concrete. Strength tests were carried out after 28 and 56 days of maturation. Experimental tests of concrete after initial thermal treatment were also carried out at three selected temperatures: 300, 500 and 700 °C, with loading times ranging from 60 to 180 min. These times were selected in such a way that the samples could be heated in their entire volume. A separate group of experimental studies was microstructure studies, the aim of which was to assess the changes occurring in concrete under the influence of high temperatures and to try to justify why CS-I concrete containing cenospheres in the amount of 20% of concrete subjected to annealing at 300 °C has a higher compressive strength than the corresponding reference concrete. The negative influence of cenospheres on the strength of concrete after initial thermal treatment was unequivocally demonstrated. An increase in the amount of cenospheres causes a decrease in compressive strength. A similar negative relationship was also demonstrated in the case of non-heat-treated samples. Graphical Abstract

Effect of Coarse Aggregate Type on the Fracture Toughness of Ordinary Concrete

This research work aims to compare the strength and fracture mechanics properties of plain concretes, obtained from different coarse aggregates. During the study, mechanical parameters including compressive strength (fcm) and splitting tensile strength (fctm), as well as fracture parameters involving critical stress intensity factor (KIcS) and critical crack tip opening displacement (CTODc) were evaluated. The effect of the aggregates used on the brittleness of the concretes was also analyzed. For better understanding of the crack initiation and propagation in concretes with different coarse aggregates, a macroscopic failure surfaces examination of the tested beams is also presented. Crushed aggregates covered were basalt (BA), granite (GT), and limestone (LM), and natural peeble gravel aggregate (GL) were used in the concrete mixtures. Fracture toughness tests were performed on an MTS 810 testing machine. Due to the high strength of the rock material, the rough surface of the aggregate grains, and good bonding in the ITZ area between the aggregate and the paste, the concretes with crushed aggregates exhibited high fracture toughness. Both of the analyzed fracture mechanics parameters, i.e., KIcS and CTODc, increased significantly in the case of concretes which were manufactured with crushed aggregates. They amounted, in comparison to concrete based on gravel aggregate, to levels ranging from 20% for concrete with limestone aggregate to over 30% for concrete with a granite aggregate, and to as much as over 70% for concrete with basalt aggregate. On the other hand, the concrete with gravel aggregate showed the lowest fracture toughness because of the smooth surface of the aggregate grains and poor bonding between the aggregate and the cement paste. However, the fracture process in each series of concrete was quasi-plastic in the case of gravel concrete, semi-brittle in the case of limestone concrete, and clearly brittle in the case of the concretes based on granite and basalt aggregates. The results obtained help to explain how the coarse aggregate type affects the strength parameters and fracture toughness at bending.

Experimental and finite element studies on the mechanical properties of high-strength concrete using natural zeolite and additives

Addressing high carbon footprints is a critical global problem in cement production. Using environmentally friendly materials has proven to be a solution to environmental challenges. In this study, High-Strength Concrete of M60 is produced with Natural Zeolite and industrial waste materials. The combinations of 5 % zeolite and varying percentages of industrial wastes such as Silica Fume, Metakaolin, and Fly Ash are tested for mechanical properties. The laboratory test data is compared with numerical simulations to assess the accuracy and determine the error percentage for concrete strength predictions. The process involves the development of numerical solutions by ANSYS to predict strength. The developed numerical solution determines the accuracy of identifying the difference between the experimental and numerical data. The present research on the comparison of experimental and numerical data by ANSYS showed the lowest error percentage, which is acceptable for all the strength properties of concrete.

Analytical Overview of the Methods of Controlling the Parameters of Vibratory Compaction of the Concrete Mixes

Introduction. A historical (retrospective) overview of the evolution and application of the methods of concrete mixture compaction by vibration, as well as an overview of the breakthrough scientific+ advancements in the studied field have been presented. The use of the dry concrete mixes that reduce cement consumption, accelerate the strength gain of concrete, reduce the shrinkage strain and heat emission and increase the strength and durability of products has been proposed. The theoretical and practical issues of vibratory compaction of the concrete mixes, the research on the effect reached by the various vibration modes of the vibrating tables, the issues of choosing an efficient mode of vibration impact during compacting the concrete mixes and optimisation of their parameters have been studied. The vibrating table design, the installation layout of the vibrator’s eccentric weights to obtain a given value of the exciting force and the layout of a vibration module with the directed vibrations have been studied in detail. The criteria of duration of the concrete mixture compaction have been defined, changes of the impact parameters during compacting the concrete mixes have been characterised and technical specifications of the vibrating tables have been defined. In the article considerable attention has been paid to the main parameters of the vibrocompacting machines: frequency, amplitude and acceleration of the working member. Most often, the parameter of intensity is used to assess the efficiency of the vibration impact received by the mixture during the compaction process.Materials and Methods. A mixture that turns into concrete after compaction, setting and hardening was selected for the research. The various methods and parameters of concrete mixture compaction to obtain the high-quality concrete were studied. The impact of the various vibration modes on the process of compaction of concrete mixes was investigated, the criteria for the efficient selection and optimisation of the vibration impact parameters were revealed. The paper presents the criteria for assessing duration of the concrete mixture compaction and describes the changes in the parameters during compaction of the concrete mixes. The technical specifications of the vibrating tables of different types and sizes were also presented. The choice of the vibration compaction mode for the concrete mixture is a complicated task, which includes many parameters.Results. Upon the research, the data on the process of concrete mixture compaction under the impact of vibration forces has been obtained. The process results in the destruction of the structural bonds and weakening the bonds between the particles, which leads to the emergence of a variable stress-strain condition. It has also been found that under such settings, the mineral particles get transferred and a denser packing is formed.Discussion and Conclusion. The resulting denser packing of the concrete mixture particles ensures the undoubted economic advantage due to reduced consumption of a binder without loss of the strength properties of concrete.
