Abstract

1. A process for the preparation of calcium silicate granulates or powders, respectively, having a microporous structure by reacting crystalline and optionally amorphous silicium dioxide or materials containing this or these, respectively, with calcium oxide or materials containing this, respectively *, in a molar ratio of CaO to SiO2 of 0.8:1 to 1.1:1 with homogenizing them by dispersing the solid starting materials in water with adding an anion-active surface-active substance previously converted to a foam in water in the presence of air and by shaping and autoclave indurating, characterized in that one uses as a foam a microporous stabile foam which has been produced from a solution of an anion-active surface-active substance prepared by dilution with water in finest distribution in compressed air and has a liter weight of from 30 to 80 g/l the anion-active surface-active substance being employed in an amount of from about 300 to 600 g/m**3 finished product and one works without aggregate as well as one comminutes, dries and classifies the indurated product in a manner known per se.
