Mathematical Formula
Slab Volume = Length × Width × Thickness; Steel = 1% of Concrete Volume by Weight
Overview & Explanation
Calculates concrete mix volume, steel rebar reinforcement weight, and constituent materials for cast-in-place RCC roof slabs.
How It Works
- Calculates concrete volume in m³.
- Applies 1% standard steel reinforcement ratio.
- Computes cement bags, sand, aggregate, and rebar kg.
Practical Applications
- House roof slab casting
- Floor slab construction
- Balcony slab estimation
Worked Example: 10m x 8m Roof Slab (125mm thick)
Find concrete & steel.
1
Concrete Volume
10 × 8 × 0.125
= 10 m³
2
Steel Reinforcement Weight
10 × 0.01 × 7850
= 785 kg (0.785 Tons)
Frequently Asked Questions
What is the standard steel requirement for a slab?
Generally, 1% of the total concrete volume by weight (approx 78 to 80 kg of steel per cubic meter of concrete) is required for RCC slabs.
