Why 1.54 Dry Volume?

Loose fine and coarse aggregates possess 30% to 35% interstitial void volume. In addition, when cement hydrates with water, volume shrinkage occurs. 1 m³ of wet concrete requires 1.54 m³ of dry materials.

Dry Volume = Wet Volume × 1.54

IS 456 Durability Limits

IS 456 Table 5 specifies M20 as the absolute minimum permissible grade for structural reinforced concrete. The maximum free water-cement ratio for mild exposure is 0.55 with minimum cement of 300 kg/m³.

Min RCC Grade: M20 · Max W/C: 0.55

Bulk Density Standards

Cement standard density is 1440 kg/m³ (giving 0.0347 m³ per 50kg bag). Dry sand weighs ~1600 kg/m³ while graded 20mm coarse aggregate weighs ~1550 kg/m³. Wet compacted RCC weighs 2500 kg/m³.

Cement Bag = 0.0347 m³ = 50 kg
