- 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.
