The paper investigates the suitability of metakaolin and crushed sand in production of concrete. The conventional concrete M20 was made using OPC 53 grade and the other mixes were prepared by replacing part of OPC with metakaolin and crushed sand. Cement was replaced with 10% of metakaolin for all percentage replacements of fine aggregate. The fine aggregate was replaced with crushed sand in five different proportions such as 10%, 15%, 20%, 25% and 30%. The strength and durability properties of all specimens were compared with control specimen.
