Production of Fly Ash Aerated Concrete and Efficiency
2020-8-17 It is shown that at the same content of source materials the use of fly ash as a filler allows us to obtain aerated concrete with an average density of 969 kg/m 3 and a strength of 3.5 MPa. Substituting the fly ash in aerated concrete composition makes it possible to reduce its average density to 440 kg/m 3 with a strength of 1.14 MPa. The pore structure of the aerated concrete samples is investigated.
