(PDF) THE OPPORTUNITIES IN A SMALL-SCALE SANDCRETE BLOCK
A simple programme for calculating the Number of blocks, Nb = Vcs/Bv number of sandcrete blocks that can be obtained from 1 bag of cement at a given block size and cement to block ratio is Hence number of blocks (5") from 1 bag of cement @ 1: 8 shown in table mix ratio = / = 21 blocks.
