Abstract:	The building sector consumes a large amount of concrete all around the globe, and this consumption is increasing. Indian traditional concrete is made using fine aggregate derived from natural sand found in river beds as the primary raw material. Natural resources are depleting, posing an environmental threat, and as a consequence, government restrictions on sand mining have resulted in scarcity and a large rise in its price. Instead of employing traditional materials, manufacturable resources are used to make up the difference. These materials include a mixture of M sand and River sand for the substitution of fine aggregate, as well as a combination of M sand and silica fume for the replacement of ceament in certain applications. To demonstrate that the strength-related qualities of the steel fibres are much superior than those of traditional materials, the steel fibres are poured into the moulds without being compacted. It was necessary to create specimens with various steel fibre percentages, such as 4 percent, 6 percent, 8 percent, and 10 percent, in order to compare results. All of the specimens were produced in line with the standards of the International Standards Organization. Molds are allowed to dry for 24 hours before hardened specimens are removed from the moulds and placed in water for curing for seven, fourteen, and twenty-eight days. The importance of critical strengths such as compressive and flexural strength is taken into consideration and shown by the test results. This is done in order to safeguard the naturally occurring resources as well as environmentally acceptable items in order to save the environment. [ABSTRACT FROM AUTHOR]
