【 摘 要 】

The effect of joint grinding Portland cement clinker, silica component and mineral additives (diopside, wollastonite) to a specific surface of 280-300 m2 / kg on non-autoclaved aerated concrete properties (strength, average density and thermal conductivity), and also the joint grinding influence on porosity of hardened cement paste made from portland cement clinker with mineral admixtures were investigated in the work. It was found that these factors ensure the production of non-autoclaved aerated concrete with an average density of 580 kg/m3, a compressive strength of 3.3 MPa and a thermal conductivity of 0.131 W / m • ° C.
