“…Similar reduction in strength on inclusion of higher dosages of WBA was noted across the remaining curing duration. This observation is in line with the report of an investigation conducted by [32] on the engineering properties of fly ash modified fiber reinforced concrete with the 10% dosage of the flyash producing the highest flexural and compressive strength performance after curing the reinforced concrete for 28 days. It was stated in the study that higher dosages of the flyash reduced the mechanical properties of the cement composites.…”

“…The conjunctive use of waste mineral admixtures with fibers has been widely studied on the properties of NC [31][32][33][34][35][36][37][38][39][40][41][42]. Coupling benefits of fibers and fly ash helps in lessening WA capacity of fibrous concretes, improvement in workability, etc.…”

“…Coupling benefits of fibers and fly ash helps in lessening WA capacity of fibrous concretes, improvement in workability, etc. [31,43]. High-performance mineral admixtures like silica fume can improve the dispersion of fibers in the concrete matrix, which can upgrade the contribution potential of fibers toward the strength of NC [38,44].…”

Portland cement concrete is fragile in tension and it has numerous negative impacts on the environment. To deal with these issues, both fiber reinforcement and recycled materials can be utilized to manufacture sustainable and ductile concrete. In this study, the synergistic effects of high-performance mineral admixture silica fume and glass fiber reinforcement were investigated on the hardened properties of RC. For this purpose, two concrete mix families, namely, NC and RC were prepared. To understand the benefits of synergistic utilization of glass fiber and silica fume, in both NC and RC, 0.5% glass fiber was incorporated with three different levels of silica fume. i.e., 0%, 5%, and 10%. Both strength and permeability-related durability properties were investigated. Results revealed that combined incorporation of 0.5% fiber and 10% silica fume can help in the production of RC having better mechanical and durability performance compared to reference “NC”. Simultaneous incorporation of silica fume and glass fiber produces a combined effect greater than their individual effects on both mechanical and permeability properties of concrete. Silica fume plays a very dominant and positive role in the development of CS, WA, and CIPR of RC, whereas glass fiber plays a vital role in upgrading STS and FS of RC and whereas, with the addition of 0.5% glass fiber, RC can yield 8–9 times higher flexural toughness than that of the plain NC.

“…Solid Waste management stress upon using unused materials like polythene products, cement, Red mud, GGBS, SCBA, Pumecrete, Ferrochrome slag, building wastes, Cocoanut or Syali fiber and many unused environment polluting solids that is pushed in to widely used cement concrete as ingredients. For individual waste materials used either replacement or partial substitute of RCC has been studied by different authors like Rao et al [15], Reddy KVR et al [16], Teja et al [17] (for Glass fiber waste), Frias M. et al [18], Behera & Mishra S P [19], (for SCBA waste) Barbuta et al [20], De et al [21] (For glass fiber and fly ash waste), Ojha & Mishra S. P. [22] (Bauxite waste),. GRFC is a fabric manufactured product of cementitious matrix processed from cement, FA, CA, water and admixtures used in facet walls, precast panels, pipes and channels for use in building materials.…”

Coping with population growth, houses are built to meet the hike. The prerequisites for concrete and steel reinforcements have surged up globally since last 3 to 4decades. Shortage of natural building materials, increased wastes from coal based industries to augment carbon foot print has worried the engineers to reuse their wastes (such as fibres, powders, granules, etc.) as building materials ingredient. Glass fibre has improved flexural capabilities with fly ash dosages in cement concrete and alternately helps in restricting environmental degradation. Present research aims at investigating the impact of glass fiber (at 1%, 2% and 3% addition) and fly ash (dosages of 10% and 20% over the existing fly ash in PPC). The ingredients and microstructure of composites are found by either X-ray fluorescent spectroscopy or scanning electron microscope. Experimental evaluation results of the blended composite concrete parameters of RCC are experimentally evaluated and compared have shown that concrete with 10% cement substitution with fly ash and 3% fibre showed optimum compressive strength performance than the concrete without fibre and fly ash and also chemically resistant against commonly used M-20 grade of Concrete.
