1 Cubic Meter Concrete Cement Sand Ratio

Quick ratio estimate for 1 m³ of concrete with cement, sand, and aggregate volumes.

Formula: Quick estimate (1:2:4): For 1 m³ concrete, cement is about 6.3 bags (50 kg), sand 0.44 m³, aggregate 0.88 m³.

Formula

Dry volume = 1.54 x wet volume
Component volume = (ratio / total ratio) x dry volume
Cement bags = cement volume / bag yield

A common nominal mix for general concrete work is 1:2:4 (cement : sand : aggregate) by volume. Your mix ratio may vary by strength or local standard.

Concrete mixes are measured on dry volume. A typical dry volume factor is 1.54.
Bag yield depends on bag size. A 50 kg bag is about 0.035 m³ of cement.
