How are aerated concrete blocks made?

Autoclaved aerated concrete (AAC) is madewith fine aggregates, cement, and an expansion agent thatcauses the fresh mixture to rise like bread dough. In fact, thistype of concrete contains 80 percent air. In the factorywhere it is made, the material is molded and cut intoprecisely dimensioned units.

What is the compressive strength of AAC blocks?

Depending on its density, up to 80% of the volume of anAAC block is air. AAC's low density also accounts forits low structural compression strength. It can carry loadsof up to 8 MPa (1,160 PSI), approximately 50% of the compressivestrength of regular concrete.
