Estimate the required cement, sand, and gravel for 16- 0.45m x 0.60m columns for the first floor of a commercial structure. Clear height of the floor is 4m. Use class A.
The total length (or height) of the columns should be computed first.
Check coefficients for 0.45m x 0.60m under class A of 40-kg cement bag.
- Cement = 2.43
- Sand = 0.135
- Gravel = 0.270
So,
Back to 2.0. Estimating Concrete
2.7. Estimating Concrete Slabs by the Area Method
2.8. Estimating Concrete Columns by Linear Meter Method
