It is prepared by taking mix ratio 1:4:8 (1 cement : 4 Sand : 8 Aggregate). The common concrete mix ratio to create M7.5 grade of concrete is 1:4:8 (cement: Sand: Stone) by volumetric analysis. This means, 1 bucket of Portland cement mix with 4 buckets of Sand and 8 bucket of Aggregate which yields approximately 8 1/2 buckets after batching.
