The amount of sand and cement needed depends on the size of the wall and the mortar mix ratio you're using. Typically, you'll need about 7-8 bags of mortar mix (80 lb each) per 100 blocks. The sand-cement ratio is usually 3:1 or 4:1 for block walls. How do you calculate cement and sand for a block? To calculate the amount of cement …

The ratio of cement to sand should generally be 1 : 3 to 1: 6 for the mortar to be workable and strong. The use of mortars of lower cement content is unsatisfactory since any notable reduction in cement contents leads to reduced workability and less cohesion and will produce porous joints with a tendency for low frost resistance.

In general, the bulk density of cement ranges from 1000 to 1300 kg/m³ (62.4 to 81.1 lb/ft³), with an average value of around 1200 kg/m³ (74.9 lb/ft³). However, the bulk density of different types of cement can vary slightly. More importantly, the bulk density of cement is not the same as its particle density or specific gravity.
