Concrete is a mixture of cement, water, sand, and aggregates like gravel or crushed stone. When mixed, these materials undergo a chemical reaction called hydration, which makes the mixture harden into a strong, solid structure. Concrete is widely used because it is strong, durable, and can be molded into different shapes as per construction needs.

Abstract. In this work, the use of brick powders (BPs) as an alternative to sand in self-compacting concrete (SCC) is investigated. Currently, the Indian Standards permit about 10% fine materials in sand below the 150-micron sieve. There is very little research conducted to determine the impact of fines on SCC properties, and
