Optimal proportional combinations of rubber crumbs and steel slag for enhanced concrete split tensile strength

Abstract

Waste management is one of the essential issues in the global domain of environmental conservation. The flourishing promotion of the Automobile Industry in India has eventually ended up with an increase in dumped waste material, such as a waste tyre. Steel slag was also added to the improvised concrete mix (CRAC) in a frozen percentage within the cement mantle of the concrete matrix for the stabilization of the binding qualities. It was discovered that an optimal proportional combination of 12% waste rubber tyre crumbs and 9% steel slag proved to be the most techno-economically viable solution for maintaining the mandated qualities of supplied 30MPa or other base values for concrete with reference to a specific purpose due to calcium oxides. The achieved split tensile strength (3.762MPa) validated this ideal proportionate combination as the best and most long-lasting.

Environment friendly sustainable concrete produced from marble waste powder

“…Table 1: Characteristics of replacing materials in concrete mix The Portland Cement that was utilised in this experiment was manufactured by UltraTech Cement in India [46]. In this experimental investigation, mixtures of 10 and 20mm Normal Weight Aggregates (NWA's) are employed [47]. ASTM C33 standards were used to conduct several tests (Table 1 summarises the results of these testing) [39].…”

“…These specimens were utilized to determine the compressive strength and elasticity. Moreover, beam samples measuring 10 x 10 cm in cross-section and 50 cm in length were prepared for a four-point flexural tensile test [47]. The tests were conducted on the 56th day to ensure minimal strength reduction due to hydration.…”

Enhancing PVCC beam performance through PVA fiber and basalt fabric in sustainable construction: ductility, strength, and energy absorption improvements

“…By using the concrete mixer, the mixing is done, and the beams were kept for 28 days curing [40]. The plywood sheet mould is used for making beam specimens with the size of 170 mm × 250 mm × 1400 mm [41]. The typical representation of Control, PVCC layered, and Basalt Fiber Fabric Wrapped Rectangular Beam [42].…”

Non-destructive evaluation of subsurface corrosion on hot steel angle sections embedded in concrete and its repair by cement slurry and nitozinc coating

“…The specific grade of cement plays a significant role in determining the concrete's overall quality and performance [35]. The mix proportion employed for the study was based on a 1:1.5:3 ratio, which corresponds to M20-grade concrete [36]. This ratio was applied to ensure the concrete's desired properties [37].…”
