Compressive Strength Of Lightweight Concrete In Psi

Lightweight Concrete: Light weight aggregate concrete

According to ASTM structural lightweight concretes compressive strength should be greater than 2500 psi (17 MPa).. Lightweight concrete based on the method of production is classified as below:. Lightweight aggregate concrete, Aerated concrete, No-fines concrete. Out of this lightweight concrete and aerated concrete is more uses than no-fines concrete.
