Aggregates sieving

This document contains the results of sieve analyses performed on manufactured sand, natural sand, and their proposed blend for a mix design. The manufactured sand was initially 1000g and sieved through various sieve sizes down to a pan, with the majority passing a 2.5mm sieve. The natural sand was initially 500g and also sieved down to a pan. The proposed mix design combines manufactured sand, natural sand, and coarse aggregate in specified proportions to meet the gradation requirements.
