Modelling the effect of composition on the properties of gypsum concrete containing cenospheres

Abstract

Materials on the base of calcium sulphate have great promise for sustainable construction. In particular, the application of lightened gypsum concrete (LGC) to production of building partitions can give a considerable effect. To lower construction mass and expenditure of the binder introduced into mix are various light aggregates: perlite, vermiculite, sawdust, foam polystyrene granules, etc. Improving thermal properties of gypsum units these organic and inorganic aggregates increase water demand of the mix and decrease the strength of hardened material.
