Worked example
With Riser = 150, Tread = 300, Number of steps = 12, Flight width = 1.2, Waist thickness = 150, Mix grade = M20 (1:1.5:3):
STAIRCASE CONCRETE (APPROX.)0.97 m³
- Cement: 7.8 bags
- Sand: 14.4 cft
- Aggregate: 28.8 cft
- Steps: 12
Approximation: triangular steps + waist slab. Landing slabs are separate.
