Abstract

Moulded microporous samples composed of calcium silicates, xonotlite, and tobermorite, wereformed by a one-step hydrothermal synthesis reaction. The properties obtained are: 0·131–0·191 kg m⁻³ density, 0·51–0·90 MN m⁻² compressive strength, 0·25–0·40 MN m⁻² flexural strength, 0·0462 Wm ⁻¹ K⁻¹ (24°C) thermal conductivity, and 1·93% linear shrinkage under firing temperature 800°C for 24 h. The process developed was made possible by the use of accelerating admixtures, which include magnesium acetate and gypsum.
