Amount of Cement in a Pool
Find the ratio of concrete the pool has to be designed with e.g if you are using concrete of 1:4:8 (for example). Than find the volume of pouring in the pool.
The amount of cement used will be:
Amount of cement in Pool (in cu.ft) = (Total Volume of Pour x ratio of cement used in the design) / Sum of ratios of aggregates (fine and coarser ones)
1 bag of Cement = 1.25 cubic feet
No. of cement bags to be used = Amount of cement in Pool (in cu.ft) / 1.25
