Strength and Elastic Properties of Aerated Concrete Blocks (ACBs)

These Aerated concrete block is a type of masonry unit manufactured by precast technique. Aerated concrete is produced by the mixing of Portland cement, sand, water and pre-formed stable foam. The foam is produced with the help of a foam generator by using foaming agent. In this experimental study the feasibility of using aerated concrete block as an alternative to the conventional masonry units has been investigated. The preliminary studies focused estimating physical, strength and elastic properties of Aerated concrete block units. These included Initial rate of absorption, density test, water absorption test etc. The compressive strength, modulus of elasticity and the flexural strength of the units were obtained. There is scanty information on the physical, strength and elastic properties of Aerated concrete blocks. The present investigation has endeavored to study all such properties. Having obtained the results, it would now be interesting and useful to compare the results with that of conventional masonry units. Keywords—Aerated concrete block, modulus of elasticity, water absorption, wet compressive strength.
