The 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.
