Ratio 1 : 3 : 6 (10 N/mm²). Suitable for plain concrete bedding, leveling courses, and non-structural foundations.
Ratio 1 : 2 : 4 (15 N/mm²). Used for residential floors, pathways, light foundations, and retaining walls.
Ratio 1 : 1.5 : 3 (20 N/mm²). Standard RCC grade for reinforced slabs, beams, columns, and structural footings.
Ratio 1 : 1 : 2 (25 N/mm²). Heavy-duty RCC structural elements, commercial columns, and water-retaining structures.

Wet Volume = Length × Width × Thickness (or Depth) × Number of Units. Converted to dry volume by multiplying by 1.54 factor.
Wet Volume = (π × Diameter² / 4) × Height (or Thickness) × Quantity. Provides accurate volume for round structural piers.
Includes waist slab volume, individual triangular step profile volume (0.5 × Rise × Tread × Width × Steps), plus landing slab dimensions.
