How to Estimate the Quantity of Sand and Cement Required ...

If 1 bag of cement is needed for 35 blocks, therefore 86 bags of cement is needed to mould 3000 blocks (gotten by 3000/35) If 0.46728 m 3 of sand is required to make 35 blocks, therefore, 41 m 3 of sand (about 67.60 tonnes assuming density of dry sand = 1600 kg/m 3) is needed to make 3000 blocks.. For a 5 tonne tipper of 3.8 m 3 capacity, we have to order for 11 trips of sharp sand.
