Benchmark estimations recommended by CPWD and field contractors for residential and commercial works.
Add 5% extra for broken bricks and transit chipping.
Mix ratio 1 : 1.5 : 3 (Cement : Sand : Aggregate).
1:4 ratio yields approximately 100 sq.ft plaster per bag.
Each box covers 16 sq.ft (4 pieces per standard box).
RCC Concrete Mix Grades Explained
Cement : Fine Sand : Coarse Aggregate (10/20mm) proportions
| Grade | Nominal Ratio | Characteristic Strength | Primary Application |
|---|---|---|---|
| M10 | 1 : 3 : 6 | 10 N/mm² | PCC leveling layer under footings, non-structural pathways. |
| M15 | 1 : 2 : 4 | 15 N/mm² | Bed concrete for residential flooring, compound walls. |
| M20 (Standard) | 1 : 1.5 : 3 | 20 N/mm² | Most widely used for residential RCC roof slabs, beams, lintels. |
| M25 | 1 : 1 : 2 | 25 N/mm² | Heavy structural columns, footings, water tanks, commercial multi-story. |
Frequently Asked Questions
Common queries regarding material quantification and site procurement
How many bricks are required in 1 cubic foot (cu.ft) of brickwork?
In India, for standard modular red clay bricks (190mm × 90mm × 90mm with mortar joints), approximately 13.5 bricks are required per cubic foot of 9-inch wall. For a 4.5-inch partition wall, approximately 4.5 to 5 bricks are required per square foot of wall area. A 5% wastage allowance is always recommended for handling and transit breaks.
How many cement bags are required for a 1000 sq.ft RCC roof slab?
For a 1000 sq.ft roof slab of 5-inch thickness (approx 416.7 cu.ft of wet concrete) using standard M20 grade (1:1.5:3 ratio), you will need approximately 75 to 80 cement bags (50kg each), along with around 155 cu.ft of sand (~1.55 brass) and 310 cu.ft of coarse aggregate/gitti (~3.1 brass).
What is 1 Brass of sand or aggregate in India?
In Indian construction terminology, 1 Brass is equal to 100 cubic feet (cu.ft) or approximately 2.83 cubic meters. In terms of weight, 1 Brass of dry river sand weighs roughly 3.5 to 4 metric tonnes depending on moisture content.
What is the recommended cement mortar ratio for internal wall plastering?
For internal walls, a 1:4 cement-sand mortar ratio at 12mm thickness is recommended for smooth finish and strength. For external walls exposed to weather, a 1:6 or double-coat 1:4/1:6 plaster at 15mm to 20mm thickness is standard practice.
