Enhancing the Mechanical Properties of Green Concrete Blocks Mixture

Abstract Concrete is a very abundant building material and flexible in construction. Yet cement is the main material used in concrete mixture, which consumed a lot of energy and money. Cement is a very un-eco-friendly material when it comes to production and is a main contributor to global warming. On the other hand, Polymers can be toxic to people, fauna, and flora. In the last century, Egyptian citizens complained that the waste has increased, and the inappropriate waste disposal effect the Egyptian health and quality of life. The alternative is to burn the polymers; however, it will produce toxic emissions that will break down the ozone layer. Previous researchers tried to replace cement with an alternative in the concrete mixture. Therefore, this research intends to create a green concrete block with cement-less mixture and use polymers as a binding material in the blocks. This research will follow the experimental method after discussing the properties of the materials. Then a concrete mix will be created, and a percentage of cement will be replaced; thus, making a cheap concrete mixture that has less cement and is more ecological and economical. Tests will be performed to determine if the proposed concrete mixture is suitable for mass production and doesn’t violate the international standards. The performed tests will include compressive strength, tensile strength, and abrasion. finally, a cost analysis will be calculated to compare the construction costs before and after using the proposed concrete mixture.

Influence of Manufactured Sand on Fresh Properties, Strength Properties and Morphological Characteristics of Self-Compacting Coconut Shell Concrete

This research examines the fresh properties, strength performance, and morphological analysis of self-compacting coconut shell concrete (SCCSC) blended with crushed coconut shell and manufactured sand (M-sand). Crushed coconut shell (CS) was used as a coarse aggregate (CA), and M-sand replaced river sand (R-sand) at 25%, 50%, 75%, and 100%. The study focused on the workability characteristics, mechanical behavior, and microstructural analysis of SCCSC. Experiments were performed on fresh and mechanical characteristics, including slump flow diameter, T500 slump flow time, L-Box blocking ratio, V-funnel and a wet sieving stability test. Mechanical characteristics include compressive, split tensile, flexural, impact resistance and bond strength. Utilizing M-sand develops the mechanical performance of SCCSC. The morphological characteristics, using scanning electron microscopy (SEM), energy-dispersive spectroscopy (EDS), Fourier transform infrared (FTIR) and the X-ray diffraction (XRD) technique, were studied in this research work. The findings show that the addition of M-sand increases the concrete strength. The microstructural analysis demonstrates that adding different amounts of M-sand to SCCSC reduced the porosity and anhydrous cement percentage, although it increased calcium hydroxide and hydration products. The substitution of 100% M-sand at 28 days increased compressive strength by 3.79% relative to the reference SCCSC. Based on the findings, the mechanical strength of SCCSC containing M-sand significantly improved compared to the concrete with river sand.

Study of Slope Stability of the Mining Wall in an Open-Pit Coal Mine by the Paste Cut-and-Backfill Method

According to this study’s findings, slope stability problems in open-pit coal mines can be avoided, and mine wall collapse can be effectively mitigated by the use of cut-and-backfill mining techniques. The main research results are as follows: (1) The stope and waste rock’s geotechnical, physical, and mechanical characteristics were gathered and examined; the geotechnical and mechanical characteristics found in this study largely satisfy the criteria for slope stability analysis. (2) Cemented paste backfill (CPB) materials were made of mine waste rock and fly ash at a desired ratio, mixed with cement as a bond material, and were tested in the laboratory, using a combination of cement percentages of 6%, 8%, and 10% for the cement content and 25%, 30%, 35%, and 40% for the fly ash content, to determine the ideal mix for artificial ground support in underground mines, taking into account both economic and performance factors. (3) By using this model, the changes in CPB strength were investigated under various factors influencing the cement ratio, and limit equilibrium modeling was used with the FLAC-Slope 8.1 program with different cement paste backfill ratio to calculate the factor of safety for each cement percentage after 1 day, 3 days, 7 days, and 28 days of curing time (CT) to obtain the optimum compressive strength and shear straight of cemented paste backfill with high paste fill shear strength on the slope. (4) The research results are of great significance for the safety of important facilities in open-pit mines and provide a basis for the design and safety implementation of open-pit slope engineering.

Unconfined Compressive Strength Testing on Expansive Clay Soils Stabilized with Cement and Lime

Soil stabilization offers an alternative solution to overcome the problem of expansive clay soil characteristics. Unconfined compressive strength tests were conducted on original and expansive clay soils containing cement and lime to investigate the effectiveness percentage of two pozzolan materials. The amount of material stabilization with percentages 2, 4, 7, 10 % cement, and 5% lime for each sample was adopted. The dimensions of the cylindrical sample were 3’’ in height and 3/2’’ in diameter. The relative density was 80% for all samples and sheared at a strain rate of 1 %. The properties of the original expansive clay soil are (w) 40.11%, (γd ) 1.3 gr/cm³, (Gs) 2.59, (LL) 60.05%, (PL) 38.16%, (IP) 21.88% and (qu) 0.61 kg/cm2. The test results indicate that the clay exhibits high plasticity. Based on the results, the effective combination percentage of two pozzolan materials to enhance the characteristics of expansive clay soil is 2% to 7 % cement and 5% lime. However, adding 10% cement and 5% lime causes the UCS value to decrease. The finding of this investigation shows the combination of two pozzolan materials, especially cement and lime, can effectively enhance the UCS values. This enhancement is observed at specific percentages of cement and lime addition. These results underscore the importance of carefully selecting proportions to achieve desired soil stabilization outcomes.

Comprehensive analysis of cement-stabilised dredged marine soil: Evaluating physical, microstructural, and mechanical characteristics

This study evaluates the index, microstructural, and mechanical behaviour of cement-stabilised soft soil. The marine soil dredged from Hangzhou is taken for the study. Different percentages of ordinary Portland cement (OPC)by dry mass were added to the soils during reconstitution, i.e., 5, 10, 15, and 20%. The reconstituted samples were analysed in the laboratory to determine basic properties such as moisture content, void ratio, density, specific gravity, consistency limits, and particle size distribution. The microstructures of the reconstituted samples were also evaluated through scanning electron microscopy. Results inferred a significant impact on the physical properties of the soil. An increase in cement content increases the consistency limits. Additionally, the specific gravity, plasticity index, and density of the treated soil initially decreased but increased upon further addition of cement content. The microstructure of the soil transformed from a dispersed to a flocculated structure, with larger and denser particles. The change in microstructure was also evident in the particle size distribution, with an increase in cement content leading to larger size particles. Finally, the unconfined compression test conducted on the reconstituted soil indicates a substantial enhancement in strength with higher cement content and prolonged curing periods.

Penggunaan Abu Sekam Kopi dan Ordinary Portland Cement terhadap Kuat Tekan Beton Normal

Cement is one of the binders which is commonly used as a concrete-forming material. Currently, there is a lot of coffee husk waste in Takengon, Central Aceh Regency, which contains silica. The basis of using coffee husk ash and OPC cement as an adhesive on the normal compressive strength of concrete. This study aims to determine the influence of using coffee husk ash and OPC cement as an adhesive on the compressive strength of normal concrete at a percentage of 5%, 10% and 15%. The research specimen is cylindrical shape with 15 cm diameter and 30 cm height. The test was carried out at the age of 7 and 28 days by using a compressive strength testing machine. The method of making the specimen is in accordance with the SNI 7656-2012 standard. It is found from the results in the laboratory, coffee husk ash obtains silicate compounds (SiO2) 29.11%, magnesium oxide (MgO) 4.92%, calcium oxide (Cao) 5.33%, ferrioxide (Fe2O3) 4.25% and aluminum oxide (Al2O3). The average compressive strength test results of 7-day old concrete at the percentage of 5% coffee husk ash mixture was 20.21 MPa, at 10% was 20.03 MPa and at 15% was 17,25 MPa. The average compressive strength of concrete at 28 days of age with 5% coffee husk ash mixture is 20.27 MPa at 10% coffee husk ash mixture percentage 19.70 MPa and 15% coffee husk ash mixture 15.46 MPa. Comparison of the results of the compressive strength test for concrete at 7 and 28 days was higher for concrete at 7 days. The results of the different compressive strength tests between the ages of the concrete are caused by the high percentage of coffee husk ash mixture where the higher the coffee husk ash percentage, the weaker the adhesion to the concrete. The percentages of coffee husk ash and OPC cement that meet the design compressive strength of 20 MPa are at 5% and 10% respectively.

INFLUENCE OF CEMENT AND COIR FIBER ON THE MECHANICAL PROPERTIES OF RAMMED EARTH

Rammed earth, a construction is widely used globally due to its ease of availability of materials and mechanical performance. Stabilization is necessary in rammed earth construction to enhance the binding of the soil particles which in turn increases the mechanical and durability properties of rammed earth. The purpose of this research is to determine the optimum percentage of chemically treated Coir fiber dust and cement for rammed earth. Fibers and cement can be easily integrated into the soil mixture, increasing the wall's strength and durability. Compressive, flexural, and tensile strength tests were performed on the samples, and failure patterns were studied. Cement is varied in percentages of 6%, 9% and 12% and coir fiber dust (0.1, 0.2, 0.3, and 0.4 percent by weight of soil) were added as stabilizer and reinforcement. To assess the optimum strength and durability, it is recommended to utilize 0.2 percent fiber content Coir fiber dust, along with 9 percent cement by weight of soil. It is observed that with the cement and fiber dust incorporation there has been increase in the mechanical properties of rammed earth. Keywords- Cement Stabilized Rammed Earth (CSRE), Coir Fiber Dust, wet compressive strength, flexural strength.

Ferrock cement and oxalic acid for enhanced concrete strength and durability against sulphate attack

Concrete is widely known for being plentiful, durable, and strong, but it can be damaged by different chemicals and environments, that can shorten its lifespan. Consequently, there is a growing interest among researchers to find more durable, stronger, and environmentally friendly cement alternatives. This study focuses on evaluating the workability, strength, durability properties, and morphological aspects of ferrock cement-based concrete, which involves substituting varying percentages of ferrock cement (0%, 5%, 10%, 15%, and 20%) for conventional cement. Ferrock, comprising Iron Powder, Fly Ash, Lime Powder, and glass powder offers pozzolanic potential as a sustainable cement substitute. Additionally, oxalic acid is introduced into the mixes to explore its role in catalyzing reactions between CO2 and water, thereby enhancing the concrete’s strength and durability. Compressive and flexural strength are analyzed after replacing the cement with ferrock, with and without oxalic acid, while durability is assessed through water absorption and resistance to sodium sulphate solution after 28 days of curing. Nine sets of mixes, all with a consistent water-cement ratio of 0.49, are investigated. Results indicate that concrete containing ferrock-based cement, particularly with oxalic acid, exhibits superior strength and enhanced resistance to sulphate attack. The addition of 5% and 10% ferrock with the integration of oxalic acid has 32.28% and 38.7% of compressive strength respectively, the same proportion has 0.2% and 0.1% of mass loss regarding resistance to sulphate attack. Notably, a 10% ferrock replacement with oxalic acid demonstrates the highest performance of concrete as determined by the multi-decision methods.

An Experimental Study on Self Compacting Concrete with Partial Replacement of Cement by Silica Fume and Crumb Rubber

Abstract: Self-compacting concrete (SCC) is a type of concrete that can flow and consolidate under its own weight without the need for vibration. SCC has many advantages such as improved workability, durability, surface quality, and reduced noise and labour. However, SCC also requires a high amount of cement and fine materials, which increases the cost and environmental impact of concrete production. Therefore, the use of supplementary cementitious materials such as silica fume and crumb rubber is beneficial to reduce the cement content and enhance the properties of SCC. This study aims to explore the effects of mixing silica fume and crumb rubber on the fresh and hardened properties of SCC. This involves the preparation of various concrete mixes with different percentages of cement replaced by silica fume and crumb rubber. Through a series of experiments, we evaluate the fresh and hardened properties of the SCC mixes, fresh properties such as workability, passing ability, and filling ability, while hardened properties including compressive strength, tensile strength, and flexural strength. The result obtained from these tests are compared with conventional concrete of M30 grade od concrete specimens. Hence the use of silica fume and crumb rubber leads to reduction in cement quantity for construction purpose and its use should be promoted for better performance as well as environmental sustainability.

Assessing the zeolite’s effectiveness on the mechanical performance of cement-stabilised sand through triaxial test and microstructure analysis

ABSTRACT In this research, a series of consolidated drained compression triaxial tests were carried out to investigate the mechanical performance of Babolsar sand. Next, the parameters such as cement zeolite substitution percentage, cement content, and curing time were determined. The results revealed significant mechanical strength of specimens by replacing zeolite up to 35% compared with cemented sand mixtures for all ranges of cement percentages. Also, the samples showed more ductile behaviour due to increasing strains at failure. Increasing the zeolite substitution by up to 35% generated shearing band failure. However, exceeding the 35% substitution, the barrelling shear mode was predominant. All samples were compressed initially until reaching a point of instant zero dilation and then dilated until the end of the tests. The dilation tendency was higher in zeolite percentages up to 35%. Moreover, increasing the cement content enhanced the dilation of specimens due to hardening and interlocking cement and sand with zeolite. Finally, microstructure analysis results showed the Si/Ca ratio as a key index to approximate triaxial shear strength development.

Experimental Investigation of Sustainable Concrete Production using Blast Furnace as A Cement Substitute- A art of Review

The pursuit of sustainable construction practices has led to a growing interest in alternative materials that can reduce the environmental impact of traditional concrete production. This experimental study focuses on the utilization of blast furnace slag as a substitute for cement in concrete, aiming to assess its mechanical properties, environmental impact, and overall sustainability. The primary objectives of this research are threefold. Firstly, the study seeks to evaluate the mechanical properties of concrete by varying the content of blast furnace slag in the mix, with a specific emphasis on strength, durability, and structural performance. This involves conducting a comprehensive analysis of the concrete's compressive strength, flexural strength, and other relevant mechanical characteristics. Secondly, a life cycle assessment (LCA) will be employed to analyze the environmental impact of the concrete mixtures. This assessment will compare carbon dioxide (CO2) emissions, energy consumption, and overall sustainability of the concrete produced with varying percentages of blast furnace slag. The LCA will provide valuable insights into the environmental implications of using slag as a cement substitute, aiding in the identification of eco-friendlier concrete production practices. Lastly, the research aims to assess the environmental impact of blast furnace slag itself when employed as a cement substitute. This involves examining the production, transportation, and incorporation of blast furnace slag into the concrete mix, providing a holistic view of its sustainability across the entire life cycle. The experimental approach involves the meticulous design of concrete mixes with different percentages of cement replaced by blast furnace slag. The varying mix designs will be tested for mechanical properties, and the data obtained will be used to draw correlations between slag content and concrete performance. In summary, this research endeavors to contribute to the body of knowledge surrounding sustainable concrete production by exploring the mechanical, environmental, and sustainability aspects of utilizing blast furnace slag as a cement substitute. The findings of this study are anticipated to provide valuable insights for the construction industry to adopt more environmentally friendly practices while maintaining or enhancing concrete performance.

EFFECT ON COMPRESSIVE STRENGTH OF CONCRETE WITH ADDITION OF SOLID WASTE ASH

The availability of raw material is very limited due to the increased use of concrete. The standard practice of concreting is dosing, mixing (all raw materials), transportation, on-site compaction, finishing and hardening of all raw materials are done industrially. In developed countries like India, the amount of concrete is more and the availability of raw materials is very limited. A complete replacement of concrete is not possible, because no material can fulfil the role of concrete in terms of strength, durability and workability. To achieve the desired workability, strength and durability of concrete, the entire material must be partially replaced. This article provides an explanation of solid waste ash materials used in concrete. The test procedure involved preparing concrete samples with a percentage of cement replaced by fly ash (0%, 5%, 10% and 15%) and evaluating their compressive strength (7 and 28 days) and split tensile strength after 28 days of curing.

Mechanical performance of low-carbon ultra-high performance engineered cementitious composites (UHP-ECC) with high-volume recycled concrete powder

Reusing recycled concrete powder (RCP) from construction waste for ultra-high performance engineered cementitious composites (UHP-ECC) markedly enhances its sustainability. This paper explores the mechanical properties and environmental benefit of low-carbon UHP-ECC containing high-volume RCP as the replacement of cement, ground granulated blast furnace slag (GGBS) and silica sand. The results indicate that UHP-ECC has a loose microstructure when a high percentage of cement is replaced with RCP, while replacing silica sand with RCP results in a denser microstructure. Substituting 75% of cement with RCP reduces the compressive strength and flexural strength of UHP-ECC by 24% and 17.6%, respectively. Substituting RCP for silica sand and GGBS does not significantly affect the compressive strength of UHP-ECC, albeit slightly reducing its flexural strength. Under the application of uniaxial tensile loading, the introduction of RCP improves the ductility of UHP-ECC at a 25% substitution rate, whether replacing silica sand or binder materials. However, as the substitution rate increases, replacing cement and silica sand with RCP decreases the ductility of UHP-ECC. Specifically, reductions of 10% and 7.6% in ultimate tensile strain are discerned when substituting 75% of cement and 100% of silica sand with RCP in UHP-ECC, respectively. Conversely, substituting a large volume of GGBS with RCP can further enhances the ductility of UHP-ECC, with an 15.5% increase in ultimate tensile strain when replacing all GGBS with RCP. By adjusting the RCP content to serve as an alternative to traditional binders and sand, it is possible to achieve a more sustainable UHP-ECC characterized by ideal mechanical strength and ductility, and RCP-blended UHP-ECC demonstrates favorable environmental and economic benefits.

Improvement of Mechanical Properties of Compressed Earth Blocks with Stabilising Additives for Self-Build of Sustainable Housing

Earth building technologies are increasingly being used to promote a natural and sustainable construction model and to empower self-building in resource-limited areas. This work focuses on investigating the use of different types of stabilising additives in compressed earth blocks (CEBs). To this end, empirical studies and laboratory analyses of earth samples taken from different sites in Ecuador were combined. Once the most suitable earth for use as a building material was determined, four types of CEBs were produced using equipment designed ad hoc to encourage self-building: earth-based, fibre additives, cementitious additives, and additives of other origin. The panels were characterised by means of compression tests to analyse their mechanical behaviour, obtaining the most promising results for the additivated samples with the highest percentage of cement and for the sample containing ground reeds, with a compressive strength of 3.3 MPa and 0.7 MPa, respectively. These samples were then subjected to more extensive tests using digital image correlation to analyse their full field strains and cracks, where the samples stabilised with cement showed a more homogeneous and consistent behaviour. Finally, an economic and comparative study with conventional construction systems was carried out to demonstrate the feasibility of using the proposed earth materials for cleaner and more economical buildings, mainly due to cost savings and lower pollution in terms of transport when using local resources.

Effect of Waste Brick Clay Powder on Self Compacted Concrete

This research investigates the effect of waste clay bricks powder in producing self-compacting concrete by partial replacement of cement. Bricks were crushed to particle sizes smaller than 75 microns. Percentages of cement of 5, 10 and 12.5 % by weight were replaced by the power at w/c ratios of 0.4, 0.425 and 0.45. Fresh concrete workability then measured and hard concrete properties were determined at 28 days. The results show that waste bricks powder can be utilized partially instead of cement to produce concrete with self leveling fresh properties and good hard properties. Consequently, this proves that waste bricks can be recycled to minimize both the effect of waste material on the environment and the heat needed for cement production.

Evaluating the Effect of Cement and ARG Fiber on the Mechanical and Microstructural Properties of Dune Sand

Despite its collapsible nature and weakness, desert sand can be used for construction purposes all over the world if properly stabilized. Therefore, the aim of this study is to evaluate the effectiveness of cement and fiber in stabilizing locally available dune sand. A test plan was used to investigate the effects of varying quantities of alkali resistance glass (ARG) fiber (F: 0%, 0.2%, 0.4%, and 0.6%) and portland cement (C: 0.0%, 1.0%, 3.0%, and 5.0%) on the mechanical and microstructural properties of dune sand. Mechanical properties such as unconfined strength (UCS), strain at failure (εf), California bearing ratio (CBR), and modulus of elasticity (Es) were evaluated, and microstructure properties were investigated using Raman spectrum and laser-scanning microscopy (LSM) tests on stabilized sand samples. The results of the experimental study showed that the percentage of cement in the treated sand has a more significant impact on the investigated properties of the treated sand than the percentage of fibers. In addition, increasing fiber content results in an increase in the ductility of the sand mix. Raman analysis revealed significant interactions between sand mix components. Moreover, LSM results showed that fiber–cement interaction increased with increasing cement percentage, as calcium silicate hydrates (CSH) formed in the mix and filamentous and intrastrand binding occurred. The findings of this study indicate that ARG fiber and cement can be effective in the stabilization of dune sand for construction purposes even with the use of low percentages of ARG fiber (0.2%–0.4%) and cement (3%).

Effects of Cement Treatment on Water Retention Behavior and Collapse Potential of Gypseous Soils: Experimental Investigation and Prediction Models

Gypseous soil poses a significant challenge in geotechnical engineering due to its susceptibility to collapse under saturation. This type of soil covers approximately 33% of regions in Iraq, primarily in unsaturated conditions. This study focuses on two types of gypseous soils: one with moderate gypsum content from Karbala city (G1) and the other with high-gypsum content from Tikrit city (G2), to investigate the effects of cement treatment on their water retention behavior and potential for reducing collapse. Different percentages of cement were mixed with both soils to determine the optimum soil–cement mixture for reducing collapse potential (CP) through single oedometer tests. The water retention characteristics and water retention behavior of samples with varying gypsum content and different levels of cement treatment were examined and compared using a controlled-suction oedometer. The soil–water retention curve (SWRC) of these natural and treated gypseous soils was also investigated and compared in both wetting and drying paths. Additionally, multiple pedotransfer functions (PTFs) were assessed to identify or adapt prediction equation(s) for the SWRC of gypseous soil both with and without cement treatment with acceptable accuracy. The results show that adding cement can decrease the CP of gypseous soils; it also affects their SWRC significantly. By making some simple modifications, the PTFs demonstrate acceptable estimations for the water retention curve of both natural and cement-treated gypseous soils.

Comparative Study of Destructive Method and Non-destructive with Ultra-Sonic Pulse Velocity Method

The appropriate percentages of cement, fine aggregates, coarse aggregates, and water are utilized to make concrete. Due to its relatively low price and widespread availability, it is a ubiquitous building material. Concrete in its fresh state can also be molded into any desired shape and size. Strength and durability are two of concrete’s most important characteristics (particularly when used for structural purposes). Verify the concrete’s compressive strength before placing it under the expected loads. NDT methods, both destructive and non-destructive, can be used to assess the compressive strength of hardened concrete. A non- destructive test does not harm the concrete specimen, whereas a destructive test (DT) crushes the cast specimen until it breaks. In non-destructive testing, materials, components or assemblies are inspected, tested or evaluated without destroying their serviceability. This study compares the compressive strength of concrete utilising an ultrasonic pulse velocity approach, which is both destructive and non-destructive. Concrete cubes measuring 150 mm by 150 mm by 150 mm were created using the concrete mix grades 25N/mm2 and 30N/mm2, and they were allowed to cure for 28 days. There were 12 cubes produced and used for the study. The determine compressive strength between destructive and non -destructive (ultra-sonic pulse velocity) test method.

An experimental study on strength of concrete having calcium carbonate as a partial replacement material to cement and natural river sand

Limestone is a sedimentary rock mainly composed of calcium carbonate mineral. Limestone is quarried abundantly in and around Piduguralla region, Andhra Pradesh, India. Good quality limestone is used to manufacture cement. Calcium oxide is used as white wash which is obtained by heating calcium carbonate. Limestone, as fine powder or as coarse grains is also used as base for paint. In this research, the calcium carbonate mineral in the form of limestone procured from Piduguralla region is used in concrete in two different forms i.e as powder form and as sand form. The cement was partially replaced with the calcium carbonate powder when the calcium carbonate is used as fine powder. The natural river sand was partially/fully replaced with calcium carbonate sand when the calcium carbonate is used as sand (coarser) form. Experiments on cube, cylinder and beam specimens are conducted using Universal Testing Machine to establish compression strength, split tensile strength and flexural strength of concrete having calcium carbonate. The test results support the usage of calcium carbonate in concrete to enhance the strength of concrete. Up to thirty percent cement can be replaced with calcium carbonate powder without adversely affecting the strength of concrete. Natural river sand can be partially/fully replaced with calcium carbonate sand which in turn increases the strength of concrete, but the optimum percentage of replacement is fifty percent of natural sand

Sustainable Utilization of Marble Dust and Rice Husk Ash as a Partial Substitute for Fine Aggregate in Concrete

A sustainable method for partially substituting fine aggregate in concrete with marble dust and rice husk ash is described. This approach focuses on the utilization of these materials to minimize environmental impact while maintaining the integrity of the concrete structure. In this study, the fine aggregate was partially substituted with marble dust and rice husk ash. Additionally, sisal fiber was incorporated as secondary reinforcement for concrete at percentages of cement by weight. Concrete has good compressive strength but is weak in tension and bending. Thus, sisal fibers were added to enhance the mechanical properties. Sisal fibers were included at 0.1% and 0.2% of cement weight for varying percentages of mineral admixture substitution. 30% of cement was replaced with mineral admixtures, with replacement levels of 0%, 10%, 15%, 20%, and 30% of marble dust and rice husk ash. The slump cone and compaction factor tests were performed on fresh concrete mixes to determine workability. Standard cubes, cylinders, and prisms were cast to evaluate the compressive, split tensile, and flexural strengths of the hardened concrete. The results show that the replacement of cement with marble dust and rice husk ash with sisal fiber as an additional reinforcing material shows considerable improvement in tensile and flexural strength. The material properties and test results are presented graphically.
