摘要：

Laboratory specimens of autoclaved aerated concrete were produced under varying conditions, mainly with cement and lime as binders. The type and amount of reaction products, the porosity and the pore size distribution were studied. Shrinkage and compressive strength were measured. The reaction products belonged to the tobermorite group of calcium silicate hydrates and the term crystallinity was defined as the percentage of 11.3 Å tobermorite out of the total amount of calcium silicate hydrates. The shrinkage decreased with increasing crystallinity while the compressive strength increased up to an optimum value. The strength also increased with increasing amounts of hydrates and with decreasing porosity. Other features of the reaction products were indicated by thermal behaviour and micropore size distributions and may have been of importance for the mechanical properties of the material. © 1979.
