Aerated Concrete: Methods, Uses and Properties Concrete ...

The density of aerated concrete produced without sand varies from 200 to 300 kg/m 3. When the aerated concrete is produced by a mixture of cement and very fine sand, the density of the usual mixes varies from 500 to 1100 kg/m 3. In the case of other light weight concretes, the strength of aerated concrete varies with the density.

Cement consumption depends on the average-density grade as well as on cement hydration degree. Reducing the latter from 1 to 0.6 in D500 concrete raises cement consumption by 7.4 %; other grades have similar patterns. This is why aerated concrete should be conditioned to maximize the utilization of the binder by enabling its complete hydration.
