The Influence of Secondary Raw Materials on Properties of Aerated Autoclaved Concrete

Popis výsledku v původním jazyce

Aerated autoclaved concrete (AAC) is a building material consisting of lime, cement, siliceous components, and aerating agents. The samples are cured by hydrothermal conditions in order to achieve a solid structure by the tobermorite formation. This article is focused on the possibilities of alternative raw material utilizations by preparation of aerated autoclaved concrete and its influence on the workability of fresh mix, water consumption, and basic physical-mechanical properties of hardened samples. Basic raw materials such as lime, cement, sand, aluminium powder, gypsum, and FBC fly ash were used in the experiment. At 20% wt., recycled glass, coal slag, and two types of fibre-like glass were used as a substitution for sand. As a first step, properties in their fresh state were determined, mainly consistency and how it was influenced by water absorption of alternative raw materials. The results of the experiments showed that the fibre-like glass has up to twice the absorbency, and to achieve the necessary consistency it is necessary to increase the water/solid coefficient by twofold. Further, the properties in a hardened state, such as bulk density, compressive strength, and coefficient of constructive quality were determined. Fibre-like glass (FLG 2) is the optimal secondary raw material which, with its parameters, is closest to the results of those samples based on primary silica sand.
