Preparation of non autoclaved cellular lightweight concrete.
Some concrete needs to be lighter and less dense and will require more air while concrete used for very solid structures like foundations should have less.
Density and strength it has different density that ranges from 300 to 1800 kg m3 with reference to 2300 kg m3 for traditional concrete.
