It is important to plan material requirements for your dream home as accurately as possible to minimize wastage as well as insufficiency of material during construction. Here are some thumb rules to consider while planning material requirements of your dream home.
Reinforced Cement Concrete (RCC) Work
Material requirement for 1 cubic meter of RCC is given in the table below.
Concrete Mix: M25 (1:1:2 approx.)
| Water and Cement Ratio | 0.35 |
| Water (Liter per Bag of Cement) | 17.5 |
| Cement (Bags) | 11.2 |
| Sand Stone (Cubic Meter) | 0.40 |
| Aggregates (Cubic Meter) | 0.80 |
| Steel Rebar (Kg) | 80-120 |
Concrete Mix: M20 (1:1.5:3 approx.)
| Water and Cement Ratio | 0.42 |
| Water (Liter per Bag of Cement) | 21.0 |
| Cement (Bags) | 8.0 |
| Sand Stone (Cubic Meter) | 0.42 |
| Aggregates (Cubic Meter) | 0.83 |
| Steel Rebar (Kg) | 75-115 |
Concrete Mix: M15 (1:2:4 approx.)
| Water and Cement Ratio | 0.55 |
| Water (Liter per Bag of Cement) | 27.5 |
| Cement (Bags) | 6.2 |
| Sand Stone (Cubic Meter) | 0.43 |
| Aggregates (Cubic Meter) | 0.87 |
| Steel Rebar (Kg) | 70-110 |
Note :
Indian Code IS 456:2000 has recommended that minimum grade of concrete for PCC and RCC is M 20 (1:1.5:3 approx)
Brickwork Material Estimation
Material Requirement for 1 cubic meter of brickwork for various mortar mixes are given in the table below.
| Mortar | 1:3 | 1:4 | 1:6 |
| Cement (Bags) | 2.6 | 1.9 | 1.4 |
| Sand (Cubic Meter) | 0.267 | 0.275 | 0.299 |
| No. of Bricks | 500 | 500 | 500 |
Plaster Work Material Estimation
Material requirement for 100 square meter of plaster of 12 mm (1/2 inch) thick is given in the table below.
| Mortar | Cement (Bags) | Sand (Cubic Meter) |
| 1:2 | 21 | 1.4 |
| 1:3 | 15 | 1.5 |
| 1:4 | 12 | 1.6 |
| 1:6 | 9 | 1.8 |
Note :
Add about 5% more material for wastage in all estimates.
