Durability and ecological assessment of low-carbon high-strength concrete with short AR-glass fibers: Effects of high-volume of solid waste materials

The goal of this research is to improve the mechanical characteristics and durability of concrete while adhering to green and sustainable development principles. Portland cement (PC) was replaced with ceramic waste powder (CWP), glass powder (GP), and granite waste powder (GWP) to create the low-carbon, high-strength concrete (HSC). These materials were incorporated at 0–50% as a partial replacement of PC. The short alkali-resistant (AR-) glass fiber content was added by 1.0% of the PC content. The changes in strength, microstructure, pore structure, as well as ecological assessment of HSCs was investigated. Various experiments on the durability properties and elevated temperature resistance of HSC were performed. The experimental results show that mechanical properties of HSC with 10%GP and 20%GWP were maximally enhanced at 28d, while the mechanical properties of HSC with 50% of all wastes are decreased. It was found also that HSC containing CWP showed significant reductions in carbonation depth (up to 65.89% lower than the control mixture), especially at higher replacement levels. Furthermore, the increment in substitution level of CWP has found an increment in pore volume, resulting in a reduction in preliminary strength performance. It was observed that a 50% substitution level of GP and GWP reduced the water penetration depth by 47.71% and 65.7% compared to the control mixture, respectively. The residual strength after 600 °C exposure for 10%CWP, 10% GP, and 20% GWP retained about 34.10%, 32.32%, and 43.29%, respectively, from their original strength. XRD tests and SEM micrographs showed that adding 10%GP and 20%GWP improve the hydration reactions. Finally, environmental assessments revealed that incorporating CWP, GP, and GWP into HSC led to reduced costs, energy consumption, and carbon footprint.

Investigation on mechanical behavior of engineered cementitious composites incorporating alkali‐resistant glass fiber and quarry dust

AbstractAt present, engineered cementitious composites (ECC) are rapidly replacing ordinary concrete in the building production due to its superior durability and mechanical qualities. Enormous researches have been done on ECC incorporating various fibers, industrial wastes, supplementary cementitious materials and super plasticizers. As far as fiber is concerned, poly vinyl alcohol fiber was widely explored. In this study, attempt has been made to involve alkali resistant glass fiber as a replacement for poly vinyl alcohol fiber. In addition, the high rate related with ECC as a result of the utilization of micro‐sized silica sand has restricted its extensive pertinences. Thus, this study recommends utilization of quarry dust to replace fine silica sand in the ECC at amounts ranging from 0% to 100% in order to establish a green, sustainable and cost‐effective ECC. The flowability and mechanical demeanor of the ECC mixtures in terms of the tensile, compressive and flexural properties were evaluated. It is arrived that 2% of volume fraction would be the optimum dosage by which better mechanical properties can be achieved. As a result of the present research findings, it is found that the quarry dust could be a better substitute for silica sand up to 75% without any compromise in compressive and flexural strengths. To attain higher tensile qualities, however, it might not be appropriate to replace more than 50% of the silica sand with quarry dust. Cost analysis of the ECC mixtures show that using quarry dust as aggregate is both cost‐effective and sustainable.

Performance of Fly-Ash- and Cement-Bound Granular Mixtures with Dispersed Fiber Reinforcement—A Case Study

This paper investigates the effects of incorporating dispersed fibrous reinforcement in hydraulically bound granular 0/16-mm mixtures. The evaluated fibrous reinforcement comprised a mixture of polypropylene and alkali-resistant glass fibers in a 1:2 weight ratio. The fibrous reinforcement was added to the mixtures in amounts of 0.05% and 0.10% by weight. The prepared mixtures utilized 1% of CEM II/B-V 32.5 R Portland cement together with 3.5%, 7%, and 14% of fly ash, characterized by a high content of reactive calcium oxide. It was found that the fibrous additives had only a small effect on the maximum dry densities and virtually none on the optimum moisture contents of the mixtures. The use of the fiber mix significantly improved the compressive strength of the reinforced samples resulting after 42 days of curing, with a performance comparable to a reference mixture bound with 8% of Portland cement. The addition of fibrous reinforcement increased the indirect tensile strength of the mixtures by up to 300%, resulting in a performance similar to that of a reference mixture with 5% of Portland cement. It was found that the use of this particular fibrous reinforcement significantly improved the performance of predominantly fly-ash-bound granular mixtures, allowing the reduction in cement content used in this type of material.

Alkali resistance prediction and degradation mechanism of basalt fiber: Integrated with artificial neural network machine learning model

Basalt fiber is commonly regarded as an alkaline corrosion-resistant material, capable of being transformed into various products (such as basalt fiber roving, chopped yarn and composite reinforcement). However, the main composition of the basalt fiber network skeleton consists of Si ∼ O bonds, which can still react with ∼OH in the alkaline environment. Nevertheless, there are differing viewpoints on the alkaline corrosion of basalt fibers within literatures. Therefore, this study aims to select three representative types of basalt fibers and compare them with two alkali-resistant glass fibers and one regular glass fiber. The attenuation mechanism of basalt fibers were investigated through orthogonal experiments, practical application scenarios and microscopic characterization methods. Additionally, we employed the Weibull model to analyze failure probabilities after erosion on basalt fibers while also applying a machine learning artificial neural network (ANN) model for predicting their alkali resistance. The results indicated that the tensile strength of basalt fiber tended to decrease and the alkali resistance of basalt fiber between alkali-resistant glass fiber and regular glass fiber in four alkaline solutions. The Weibull model also confirms that erosion increases failure probability of basalt fiber and glass fiber. Moreover, Si ∼ O, which forms the network reacted with OH-, resulting in a reduction in surface Si and Al elements content. It became possible to predict the alkali resistance of basalt fiber accurately by establishing an ANN model. Our study provide a theoretical foundation for predicting the lifespan of basalt fibers under corrosive conditions while offering guidance for enhancing their alkali resistance.

Preparation and application research of hybrid alkali-resistant glass fiber reinforced cement grout

Cement grouting reinforcement is a widely used method for controlling water inrush in tunnels. However, traditional cement grout has certain limitations such as low strength and susceptibility to erosion, which can result in inadequate grouting performance in water-rich tunnels. To address this issue, this study introduces a novel type of grout called hybrid alkali-resistant glass fiber reinforced cement grout (HARGFC). In order to evaluate its effectiveness, different ratios of HARGFC were tested in terms of slurry fluidity, splitting tensile strength, compressive strength, and flexural strength through laboratory experiments. Additionally, microscopic analysis of the samples was carried out using scanning electron microscopy (SEM) in conjunction with the mechanical tests. Finally, the application of HARGFC was demonstrated in a water-blocking grouting project conducted in the Qiyue Mountain Tunnel on the Liwan Expressway. The results demonstrated that this material possesses outstanding physical and mechanical properties, as well as alkali resistance, which greatly enhances grouting performance in water-flowing tunnels. Adding a total fiber content of 1%, that is, 80% of Cem-FIL70 (9 mm) and 20% of HD (6 mm), yielded the optimal ratio for HARGFC. Compared to traditional cement materials, the splitting tensile strength, flexural strength, and compressive strength of the new material increased by 27.46%, 20.64%, and 7.37%, respectively. Building upon various combinations of grouting methods, the optimal HARGFC was applied to the grouting sealing and reinforcement of the Qiyue Mountain Tunnel, effectively controlling water inflow. These research findings provide valuable data and theoretical support for addressing sudden water inrush in tunnels and grouting construction.

Dynamic compression study of seawater sea sand concrete incorporated with expansive agents and glass fibre

Seawater sea sand concrete (SSSC) is an eco-friendly protection material with better development prospects than other cementitious composites. There are many projects facing dynamic compressive load during construction and operation. Therefore, it is important to explore an SSSC with excellent dynamic compression performance. In this study, alkali-resistant glass fibre (GF) was used to enhance the performance of SSSC and expansion agent (EA) was introduced to improve the interface of cement slurry. The results show that the slopes of the relationship between DIF and strain rate of F1EA6, F1EA0 and F0EA6 are 12.6%, 8.4% and 6.7% higher than that of F0EA0, respectively, which indicates that GF and EA have a more significant strain rate effect on the dynamic compression performance of SSSC. In addition, through introducing the fineness modulus of residue (MR) and scanning electron microscopy (SEM) observation to analyse the failure mode of the specimen, it further proves that GF and EA have a synergistic effect on dynamic compressive strength. This study put forward some guidelines for the future research direction of impact resistance of SSSC structure.

Experimental research on mechanical properties and elastic modulus of glass fiber reinforced concrete

By adding ordinary glass fiber and alkali resistant glass fiber into concrete, the development of axial compressive strength, axial tensile strength and elastic modulus of concrete are studied. The results show that with the increase of glass fiber, the axial compressive strength increases first and then decreases; the axial tensile strength increases; the elastic modulus decreases. The results show that glass fiber can improve the strength of concrete, and reduce the elastic modulus.

Improved mechanical and macro-microscopic characteristics of shotcrete by incorporating hybrid alkali-resistant glass fibers

Fiber reinforced shotcrete (FRS) is an essential method for engineering support such as tunnels, slopes, and foundation pits. This study focuses on addressing the limitations of traditional fiber-reinforced shotcrete (FRS) by introducing innovative alkali-resistant glass fiber (AR-GF) series products, namely Anti-Crak® HP (HP) and Anti-Crak® HD (HD) mixed FRS. The aim is to overcome issues such as rusting, corrosion, high labor, and low surface aesthetics. The mechanical and microscopic properties of alkali-resistant glass fiber reinforced shotcrete (AR-GFRS) were investigated under different conditions of admixture and mixing patterns using uniaxial compression, split tensile, and scanning electron microscopy (SEM) tests. The results show that the mixing of AR-GF series products HD and HP greatly enhanced the mechanical properties of shotcrete and improved the microstructure of shotcrete. The split tensile strength was increased by 23% with the 6% content compared to 3% with HP fiber alone. AR-GFRS in HP and HD hybrid mode has better compressive and splitting tensile strength compared with the same total content of AR-GF with HP fibers alone. The optimal amount of HP was 3% of the cement mass for single mixing of HP, and the optimal mixing pattern of HP and HD was the mixing of HP (length 24 mm) and HD (length 18 mm and 6 mm). The excellent integrity of the rupture surface can be observed from a microscopic point of view, and the AR-GF was predominantly extracted. The HP damage morphology on the rupture surface was classified into fiber integrity, breakage, disorganization, and dispersion. A hybrid AR-GFRS model was established to reveal the hybrid AR-GF shotcrete reinforcement mechanism. The research results provide new ideas for the development of mixed fiber shotcrete, and lay the foundation for the design and construction of mixed alkali-resistant glass fiber shotcrete support.

Crack behavior of expanded polystyrene foam-ceramsite composite thermal insulation mortar

To compensate for the deficiencies of thermal insulation, fire and crack resistances of traditional thermal insulation mortars, this paper prepares expanded polystyrene foam (EPSF)-ceramsites composite thermal insulation mortar (ECTIM) with ceramsite and EPSF particles as insulation aggregates. The effects of fiber content (i.e., P = 0.3%, 0.6%, 0.9%), fiber length (i.e., l = 3 mm, 6 mm, 9 mm) and fiber types (i.e., polypropylene fiber (PF), steel fiber (SF), alkali resistant glass fiber (ARGF)) on crack resistance of the ECTIM were analyzed. The test results demonstrated that the incorporation of fibers could significantly improve crack resistance and delay the cracking of mortar. With the increase of fiber content P, the water loss rate and cracking index decreased to 43.70% and 79.17% of the specimen without fiber. As the fiber length l increased from 0 mm to 9 mm, the water loss rate and cracking index decreased by 41.50% and 77.08%, respectively. Comparatively, the PF could obviously improve the crack resistance of the ECTIM. Based on the experimental research, the microscopic stress mechanism of mortar cracking, as well as the early and late anti-cracking mechanism of the ECTIM were revealed. In addition, considering the effects of fiber content and fiber length, a comprehensive influence coefficient ϖ was introduced, and a formula for conveniently calculating the maximum crack width Wmax of the ECTIM was proposed. The predicted results agreed well with the test data. The thermal insulation mortar prepared in this study could considerably overcome the deficiencies of traditional organic and inorganic thermal insulation mortars, and had excellent thermal insulation, fire and crack resistances. The resource utilization of iron tailings and the introduction of ceramsite reduced the materials cost. The prepared thermal insulation mortar could be used for wall substrate, geothermal heat insulation layer, external wall, internal wall and roof insulation.

Alkali resistance of selected waste fibres to model cement environment

Synthetic fibres are often used to reinforce cementitious composites. However, their production has significant negative environmental impact. An ecological alternative could be to use waste fibre if their properties are found to be satisfactory. Therefore, the main objective of this study was to determine if selected waste fibres could withstand an aggressive and highly alkaline environment of cementitious composites. Three types of production waste fibres (alkali-resistant glass fibres, AR-GF, basalt fibres, BF and carbon fibres, CF and recycled tyre polymer fibres RTPF) were exposed to a synthetic pore solution simulating the cement matrix condition for 90 days. The mechanical properties of the production waste fibres and the morphology determined by scanning electron microscopy were the best predictors of fibre resistance. The sizing of the treated production waste fibres partially (CF) or completely (AR-GF, BF) decomposed. The pronounced deterioration of the BF structure was accompanied by a complete deterioration of the mechanical properties. A slight deterioration of mechanical properties was also observed in CF and to an even greater extent in AR-GF. The RTPFs were too short for mechanical measurements, so a combination of Fourier transform infrared spectroscopy and thermal analysis was required to evaluate effects of exposure to synthetic pore solution. The retained properties of treated RTPF seemed to be at least equivalent to those of AR-GF. Overall, the alkaline resistance of all studied waste and recycled tyre polymer fibres appears to be sufficient to restrain early age deformation of cementitious composite.

Enhancement of Alkali Resistance of Glass Fibers via In Situ Modification of Manganese-Based Nanomaterials.

Glass fibers are widely used in cement-based precast products, given the reinforcing requirements for toughness and strength. However, inferior alkali resistance hinders the effectiveness of glass fibers in reinforcing cement-based materials. In this paper, nanoparticle coatings were applied on the surface of alkali-resistant glass fiber (ARGF) as a protective layer via the in situ chemical reaction of oleic acid (OA) and potassium permanganate (PP). The morphology and constituents of the as-prepared ARGFs were examined using scanning electron microscopy (SEM) and obtaining X-ray photoelectron spectroscopy (XPS) measurements. Mass loss and strength retention were investigated to characterize alkali resistance of modified ARGFs. Results showed that ARGFs could be optimally coated by a layer of MnO2-based nanoparticles consisting of approximately 70% MnO2, 18% MnO, and 12% MnSiO3, when modified with an optimum OA to PP ratio of 10 for 24 h. The dissolution of ARGFs matrix in 4% and 10% NaOH solutions were distinctly delayed to 28 d, as a consequence of the introduction of the MnO2-based nanoparticle layer, compared with nontreated ARGF occurring at 3 d in 4% NaOH solution. For the optimally modified ARGFs, the mass loss was controlled to 1.76% and 2.91% after 90 d of corrosion in 4% and 10% NaOH solutions, and the retention of tensile strength was increased by approximately 25%. With respect to the increment in alkali-resistant performance, the modified ARGFs can be promising candidates for wide applications in alkaline cement-based products.

Zirconia nanoparticle coating for high-strength and alkali-resistant glass fibers

In this study, the effect of zirconia nanoparticle coating on the chemical and mechanical characteristics of E-glass fibers was investigated for usage in an alkaline environment. E-glass fibers were dip-coated in aqueous zirconia nanoparticle solutions that have varying concentrations of nanoparticles. Tensile tests were conducted on bare and coated fibers to determine the impact of nanoparticles on the strength of fibers. According to the mechanical analysis, the tensile strengths of the fibers were enhanced by 10.2%, 12.2%, 14.6%, and 17.4% for 5%, 10%, 15%, and 20% of nanoparticles in the solutions, respectively. The role of zirconia coating on the alkali resistance of fibers was investigated in a NaOH-based alkaline solution. Zirconia nanoparticle-coated fibers with 15% and 20% solutions were not corroded in the alkaline environment after dwelling for 500 h. The coating also prevented the degradation of mechanical properties, and the aged fibers maintained similar tensile characteristics.

Optimisation of Mechanical Characteristics of Alkali-Resistant Glass Fibre Concrete towards Sustainable Construction

Concrete is a worldwide construction material, but it has inherent faults, such as a low tensile strength, when not reinforced with steel or other forms of reinforcement. Various innovative materials are being incorporated into concrete to minimise its drawbacks while concurrently improving its dependability and sustainability. This study addresses the research gap by exploring and enhancing the utilisation of glass fibre (GF) concerning its mechanical properties and reduction of embodied carbon. The most significant advantage of incorporating GF into concrete is its capacity to reduce the obstruction ratio, forming clusters, and subsequent material solidification. The study involved experiments wherein GF was incorporated into concrete in varying proportions of 0%, 0.5%, 0.75%, 1%, 1.25%, 1.50%, 1.75%, and 2% by weight. Mechanical tests and tests for durability were conducted, and Embodied carbon (EC) with eco-strength efficiency was also evaluated to assess the material’s sustainability. The investigation found that the optimal percentage of GF to be used in concrete is 1.25% by weight, which gives the optimum results for concrete’s mechanical strength and UPV. Adding 1.25% GF to the material results in increases of 11.76%, 17.63%, 17.73%, 5.72%, and 62.5% in C.S, STS, F.S, MoE, and impact energy, respectively. Concrete blended with 1.25% of GF has the optimum value of UPV. The carbon footprint associated with concrete positively correlates with the proportion of GF in its composition. The optimisation of GF in concrete is carried out by utilising the response surface methodology (RSM); equations generated through RSM enable the computation of the effects of incorporating GF in concrete.

A review on various properties of textile reinforced concrete

Carbon emission has been one of the most threatening problems in our environment. So it is necessary to develop new technologies that concentrate mainly on durability and sustainability of a structure without reducing various strength parameters. Textile reinforced concrete employs fibres that are provided as reinforcement instead of steel bars. This study elaborates about the properties of textile reinforced concrete. Usage of such fibres will be helpful to mitigate corrosion due to steel bars. The fibres are usually light in weight when compared to conventional steel rods. These fibres have less thickness but exhibits good strength and ductility. Experimental studies on beams proved that polymer-coated textiles showed increased load- carrying capacity. It was observed that the bonding quality had a great influence on the flexural behaviour of the same. When four- point bending test was carried out for samples with carbon textile fabric reinforcement, expected results were not obtained. The ultimate capacity was slightly over- predicted in the above mentioned case. It was found that textile fibre reinforcement reduced 60% of concrete in a structural element when compared to use of steel reinforcement. One of the issues reported was the bond between the yarn and the concrete matrix. The outer filaments of the yarn had good bonding with concrete because of its direct contact. On the other hand, the inner filaments will be conceded from concrete resulting in non– uniform strain distribution. A pedestrian bridge of span 15 m and width 3 m in Germany was constructed using Carbon Concrete Composite. Further studies proved that Alkali Resistant glass fibres had better cost efficiency and improved tensile strength. Because of its light weight, transportation costs will also reduce. Textile reinforced concrete has proven to be a cost- efficient composite material.

Strengthening of AR Glass Fibre Concrete by Using Dunite Powder

Abstract: In the contemporary era. Concrete, the most significant and frequently used material, frequently needs to have a very high strength and acceptable workability. Research on glass fibre reinforced concrete led to the development of alkali resistant fibres with a high capacity for dispersion, increasing long-term durability. When dunite is utilised as a cement alternative rather of regular cement, concrete is discovered to become up to 40% stronger. Studies based on periodic cement rate data show that, on average, dunite powder is less expensive than cement. Future cement usage will be dominated by the replacement of dunite powder. In the current experimental investigation, alkali resistant glass fibres have been employed to investigate the effect on compressive and split tensile strength on M30 grade of concrete can be determined for 28,56 and 90 days

Experimental Study of Fiber Pull-Outs in a Polymer Mortar Matrix.

In order to study the influence of vinyl acetate-ethylene copolymerization emulsions on the bonding performance of fiber and mortar, mortar materials with different polymer contents were prepared. The optimal mix ratio of the matrix was obtained using a pull-out test with a 0° inclination angle. On this basis, polypropylene fibers and alkali-resistant glass fibers were set at different burial depths (6 mm, 12 mm, and 18 mm) and different burial angles (0°, 30°, 45°, and 60°). The load-displacement curves of two types of fibers pulled out from the polymer mortar were obtained. The test results show that polymer contents of 3% and 5% increase the peak pull-out loads of glass fibers and polypropylene fibers by 16.28% and 30.72% and 7.41% and 27.11%, respectively. When the polymer content is 7%, the peak pull-out load decreases by 1.31% and 24.26%, especially for polypropylene fiber, which significantly weakens the bonding performance between the matrix and the fiber. The pull-out load of glass fibers and polypropylene fibers increases with the increase in the buried depth, and both show tensile failure at 18 mm. As the embedding angle increases, the pull-out load of polypropylene fibers decreases continuously, while the glass fiber shows a higher pull-out load at 30°.

Microencapsulated phase change material incorporated light transmitting gypsum composite for thermal energy saving in buildings

The increased energy consumption for specific applications, including heating, cooling, air conditioning and lighting of residential and commercial buildings accelerate the research efforts concentrated on developing thermal energy storage capacity of buildings materials in recent years. Likewise, the development of light-transmitting building elements is a novel energy-saving technique that enhances lighting efficiency in buildings. In light of these, the current study seeks to design an untried microencapsulated phase change material (MPCM) integrated glass fiber reinforced gypsum composite with sufficient light-transmitting properties and thermal energy storage capacity. In this research, a multi-scale investigation of light-transmitting gypsum composite was conducted experimentally with physical, mechanical, chemical, microstructural, thermal, light transmittance and solar thermoregulation tests. The gypsum composite is formed from α-gypsum, water, polymer admixture, alkali-resistant glass fiber (AR-GF), several concentrations of MPCM, and plastic optical grids to allow light to transmit through the board. Although higher fractions of MPCM yielded an apparent decrease in mechanical strength test results, 5 wt% introduction of MPCM to the reference matrix reduced the compressive and flexural strength of specimens by 1 and 8 %, respectively. The results verified a reduction trend in thermal conductivity of composites with MPCM loading. DSC investigations revealed that the melting temperature and the regarding latent heat storage capacity of gypsum composite with 15 wt% of MCPM are 17.76 °C and 19.2 J/g, respectively. Light-transmitting gypsum composites showed up to ~10 % light transmittance, that can greatly increase the efficiency of lighting in buildings. The produced gypsum composites with MPCM kept the test room cooler during the highest temperature, while it provided a warmer room during the nighttime for an extended time. The study's findings are applicable to increase thermal comfort by reducing the significant temperature variations in buildings and improving artificial lighting efficiency, encouraging the design of sustainable building applications.

An experimental investigation on the effect of lithium and alkali resistant glass fiber on aluminum AA5383 fabricated by the stir-casting process

The purpose of this experimental research is to investigate composite materials that could be utilized in shipbuilding application. These materials are fabricated by employing bare material such as aluminium 5383 alloy and are then reinforced with lithium and alkali resistant glass fiber (ARGF). Lithium, which is known for its strong ductile and malleable properties, can be added to aluminium alloy 5383 in order to bring about a reduction in the overall weight of the materials. ARGF used as a reinforcement material with aluminium 5383 to empower the more resistant to corrosion. In the course of this experimental study, four samples will be manufactured by adjusting the percentage of ARGF used. The following tests were carried out in order to optimise the chemical composition of composites: the brilnell hardness test, the tensile test, the charpy impact test, the double shear test, and the sodium chloride (Nacl) corrosion test. From the results, it was discovered that S4 had a maximum brinell hardness value of 123 BHN, the tensile strength of the sample S4 had a maximum value of 372 MPa, the highest impact strength of the sample S4 was found to be 10 KJ/m2, and the maximum double shear strength of the sample S4 was found to be 96 MPa. Add to that, S4 had good corrosion resistance qualities. The study may provide insights into the sample S4 have a potential applications of the composite material in various industries, such as aerospace, automotive, and manufacturing. The incorporation of reinforcing materials such as lithium and ARGF into metal matrices can potentially improve their mechanical and corrosion properties, which may lead to the development of new materials with improved performance characteristics.

Mechanical and Durability Performances of Alkali-resistant Glass Fiber-reinforced Concrete

Concrete, being the most widely used construction material in the world, lacks strength in direct tension and flexure. Attempts to reinforce concrete in tension include the use of steel rebars to strengthen the tensile side of concrete as well as the use of discrete fibers as a reinforcing medium. The study conducted in this manuscript details the effects of including alkali-resistant glass fibers in concrete. Mechanical strength, such as strength in compression and flexure, chord modulus of elasticity and bond pull-out strength, have been measured along with porosity and resistance to accelerated carbonation. Five different water to binder ratios in a range of 0.4 to 0.6 had been used to prepare the design mix proportions. The optimum fiber dosage was found to be 1.5% by weight of cement used. The same had been adopted in the design mix proportions. The average increase in compressive strength and flexural strength was 13% and 28%, respectively. Alkali-resistant glass fiber concrete showed less resistance to carbonation when compared to control mix. Results indicate that glass fibers play a predominant role in providing flexural strength to concrete. The pull-out strength of fiber was added to extra post-cracking flexural strength. The inclusion of alkali-resistant glass fibers imparted a maximum addition of 44% increase in the flexural strength compared to control concrete. The inclusion of alkali-resistant glass fibers in concrete paves the way for a leaner mix and eradicates the possibility of congestion of steel reinforcement for certain structures.
