Calculate a transparent preliminary concrete mix with your own fck, standard deviation, materials, sand zone, aggregate size, slump and project limits. Then buy a detailed ₹199 calculation report + Trial Mix Sheet.

Open calculator

Build a mix you can actually check

This calculator shows the calculations behind the result: target mean strength, adopted water-cement ratio, water demand, cementitious content, absolute volume, coarse/fine aggregate split and aggregate moisture correction.

Start a mix design

Useful for M20 to M55

Choose a grade as a starting point, but enter the actual characteristic strength and project standard deviation used for your design.
