This document outlines the procedure for concrete mix design according to IS:10262-2009, including calculating the target strength, selecting the water-cement ratio and water content, proportioning aggregates, and testing trial mixes. It references tables from IS:10262 and IS:456 that provide guidelines for minimum cement content and water-cement ratios based on exposure conditions, maximum water content based on aggregate size, and volume of coarse aggregate depending on the zone of fine aggregate.
