Recipe-technological aspects of improving the properties of non-autoclaved aerated concrete

Abstract

The paper dwells upon non-autoclaved aerated concrete technology issues relating to the effect of various composition and technological factors on the aerated-concrete non-autoclave products. It presents the results of experiments carried out to study the effect of three factors: the order in which components are added to the AC mixture; the efficiency of adding a complex sodium additive to the mixture; the effect of adding the structuring additive, the 'off-cut'. Comparative analysis of physico-mechanical test results revealed that adding the structuring additive increases the compression strength of aerated concrete while also making it denser.
