Technical Specifications of Concrete Blocks Parameter Description Typical size 300length x 200width x 150depth mm [depth here does not matter in this problem/solution] Average compressive strength at 28 days 50-110 kg/sq.cm Mix Proportion 1:12-14 (1 part cement : 12-14 parts sum graded aggregates) Water absorption in 24 hours Less than 10% by weight of block 2 walls 10′ x 8′ = 160 sq ft 2 walls 15′ x 8 ‘ = 240 sq ft ————– 400 sq ft If one block 300mm x 200mm = 60,000sq mm = 0.6458346250025834 sq ft 400 sq ft[total area of the two side walls plus the front and rear walls]/ 0.6458346250025834 sq ft[area of each face of one block] = 619.36 blocks or roughly 620 blocks.
