additives, as well as decreases conductivity of water and water vapor and increases strength and life of concrete [3]. At the beginning of hardening process of autoclaved aerated concrete (AAC), as in all concretes, hydrosilicates of amorphous state are forming and a nanostructure is building up. Therefore, one can expect that the properties

Abstract. We investigated the effect of joint grinding of Portland cement clinker, silica and carbonate components and mineral additives to specific surface of 280 - 300 m 2 /kg on the properties (strength, average density and thermal conductivity) of non-autoclaved aerated concrete, and the porosity of the hardened cement paste produced from Portland cement clinker with mineral additives.

The paper has investigated an impact of a complex additive (CA), consisting of continuous basalt fibres (CBF) and SiO 2 microdust (SMD), on change of strength properties in autoclaved aerated concrete (AAC) samples within recurrent heating and cooling cycles.. Content of CBF in AAC forming mixture was 0.3% from dry mass of solids.

Highlights Carbon fibre additives act as nuclei during the autoclave hardening of aerated concrete. Size of carbon fibre additives depends on the way of their mechanical treatment. The higher is amount of small carbon fibre particles the higher is degree of crystallinity. The higher is degree of crystalinity, the better are properties of autoclaved aerated concrete.
