Concrete blocks are often made of 1:3:6 concrete with a maximum size aggregate of 10mm or a cement-sand mixture with a ratio of 1:7, 1:8 or 1:9. These mixtures, if properly cured, give concrete blocks a compression strength well above what is required in a one-storey building.
How do you calculate sand and cement for CHB laying?
Based on the specified kind of mixture and CHB thickness, multiply your area with the corresponding values from the mortar proportion table:
- Quantity of Cement Bags = Area * Cement multiplier for a Class “B” mix. = 6m2 * 0.522.
- = 3.132 bags ~ 4 bags.
- Quantity of Sand = Area * Sand multiplier for a Class “B” mix.
- = 0.261 m3
