### How to Calculate Cement, Sand and Coarse Aggregate ...

For Cement, Sand and Coarse Aggregate. ... According to IS 10262 (2009), Assuming Water-Cement Ratio for the Concrete as 0.45. Required Amount of Water = W/C Ratio X Cement Volume. Therefore, Water = 0.45 X 0.3636 m 3 = 0.16362 m 3. Unit Weight of Water = 1000 litres/m 3. Required Amount of Water = 0.16362 X 1000 = 163.62 litres. Therefore, we need 10.5 bags of cement, 0.5454 m 3 of sand.
