Read MoreConcept and significance of the Aggregate crushing value test. The ' aggregate crushing value test ` gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. Aggregate crushing value is defined as the percentage by weight of the crushed (or finer) material obtained when the test aggregates are subjected to a specified load under ...
Read MoreThe range of strength for sandcrete blocks specified by N.I.S 74:1976 is between1.8N/mm2 to 2.5N/mm2 as the minimum strength. The blocks can cope with thermal and moisture conditions, and the problem of algae growth on the face of block work during construction is unlikely to affect the strength of the block (Edward, 1985).
Read MoreThe material used in the construction of a concrete block affects its load bearing capacity. For instance, a 10-by-8-by-16-inch concrete block made with stone dust may support more weight than a 15-by-12-by-24-inch block made with sand, because stone dust exhibits greater weight and strength than sand.
