Concrete mix proportions (learning only)

Absolute-volume batching from your chosen water content, w/c ratio and aggregate split. Not a design.

Educational use only; not professional design advice; always follow the current code and a licensed engineer.

Learning tool only. A real mix must follow IS 10262 or the governing code with trial mixes. Enter values you have chosen from that code; we do not reproduce its tables.

Characteristic strength f_ck (MPa) Assumed standard deviation s (MPa) Water content (kg/m³) Water-cement ratio Coarse aggregate share of total aggregate volume Entrapped air (%) SG cement SG fine agg. SG coarse agg.
