Constituent Fraction

Calculates exact percentage share of each mix ingredient.

Part Fraction = Component Parts / (Part A + Part B + Part C)
📐

Batch Volume Math

Allocates total dry volume proportionally to cement, sand, and aggregate.

Component Vol = Dry Batch Volume × Part Fraction

Water-Cement (W/C) Ratio

Optimal water ratio ensuring full hydration without compromising strength.

Water Volume = Cement Weight × 0.50
