“…The most commonly investigated type of fiber reinforcement in RC is steel fiber with and without mineral admixtures [13,14,17,18]. Polypropylene, basalt, and glass fibers have also been investigated in RC [19][20][21][22][23][24][25][26]. These studies have shown that fibers mainly contribute to flexural and tensile strength of RC.…”

“…These studies have shown that fibers mainly contribute to flexural and tensile strength of RC. With a small volumetric dosage of fiber (less than 0.5%), RC shows better tensile and flexural strength than plain "NC" [19,23]. The main contribution of fiber toward strength development of RC is credited to high tensile strength of fiber reinforcement that increases the stiffness and tensile strain capacity of plain concrete.…”

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.

“…and likewise the same replacement ratios of powder tyre Crump is called as Crump Rubber(CR) with cement. the reduction in compressive strength [2]replacing of 10%and 30%RCA,5%and10%CR and 1%and2% fibre content, As RCA,CR and fibre content increased, workability in terms of slump is reduced [3]different percentages of crumb rubber as a partial replacement of both fine and coarse aggregate by (0,10,20,and 30%)up to 10% CR compressive strength is improved. [4]replacing of river sand with manufactured sand of geo polymer concrete (0 to 100%) increase in compression strength.…”

Concrete has a key role in construction. Study focus on workability of the concrete, Fine Aggregate is partially filled with crumb rubber and M sand, a part of cement is replaced with fly ash. In this investigation the crumb rubber is utilised in place of fine aggregate. The scrap tyre treatment is currently a serious issue against environmental pollution. India stud in forth position in the entire world for rubber tyre market world after china, Europe and the US. Fly ash and M sand is an industrial waste which is included in the concrete. In this investigation workability of concrete is conducted on M20 grade concrete by replacing river side sand with the M sand and crumb rubber at percentage of replacements 0 to 20% at an regular interval of 5%and Compare the results obtained by the modified concrete with the normal concrete.

“…After crushing and fractionation construction waste you can obtain concrete recycling (crushed concrete) in the form of rubble, sand and crushing screenings (concrete dust). Recycled concrete in modern construction should be considered a tough alternative to traditionally used natural inert materials made of stone raw materials [8][9].…”

It is known that during the whole life cycle of a building it is necessary to take a responsible approach to the organization and management of construction processes at the present stage of construction. The reasons for the low use of construction waste were analyzed. It is shown that screenings of concrete scrap are the least demanded. The results of researches connected with utilizing concrete scrap to obtain building composites with high functional, economic and environmental efficiency were reflected.
