- Rate analysis of concrete used of reference book IS Code 1200 part 2 (IS Code 1200 part 2 used for measurement), IS Code 2212, and CPWD Part 1.
- All calculations of concrete for rate analysis. This calculation calculates of cement, sand, concrete (concrete = Cement + Sand + aggregate mixture this call concrete) for materials.
- Concrete is used a sum different proportions 1:0.5:1, 1:1:2, 1:1.5:3, 1:2:4, 1:3:6 etc.(1 cement: 5 Sand: 10 Aggregate). This quantity estimation of concrete is required for the rate analysis.
