Abstract

Concrete blocks are manufactured from Portland cement and selected aggregates. BS 2028, 1364 : 1968 (Precast Concrete Blocks) classifies blocks under three headings: Type “A”: Dense concrete blocks having a block density of not less than 1500 kg/m3 (93.61b/ft3). The block density is obtained by dividing the weight of a block by the overall volume, including holes and cavities. Aggregates may be sand and crushed gravel, crushed slag or broken brick. Type “A” blocks are suitable for general use in building, including work below D.P.C.
