For the mix of 10 m³ of 1:3:6 cement concrete.
The wet mix volume increases by about 52% compared to the dry mix:
-
Wet mix volume = 10 m³ × 1.52 = 15.2 m³.
Material Quantities:
-
Cement: (1/10) × 15.2 = 1.52 m³
-
Coarse Sand: (3/10) × 15.2 = 4.56 m³
-
Stone Ballast: (6/10) × 15.2 = 9.12 m³
Material Cost:
-
Cement: ₹10,000 per m³ × 1.52 m³ = ₹15,200
-
Coarse Sand: ₹2,000 per m³ × 4.56 m³ = ₹9,120
-
Stone Ballast: ₹3,000 per m³ × 9.12 m³ = ₹27,360
Total cost = ₹15, 200+ ₹9, 120+₹27,360 = ₹51,680.
