As with any building material, it does have its share of complete/completely acceptable alternatives. Disadvantages Of Hollow Bricks i) The compressive strength and load-bearing capacity of hollow bricks are much lower than first-class clay bricks. The average density of clay bricks is 125pcf. Because the cement requires time to fully hydrate before it acquires strength and hardness, concrete must be cured once it has been placed and achieved initial setting. It is nearly impossible to lower noise transmission once a house is built. 1.
