Abstract
Process techniques are proposed for separate addition of polydisperse filler fractions in the preparation of casting molding mixtures based on chamotte — quartz binder suspensions. The effect of the fractional composition of the filler in such mixtures on the physico- and thermomechanical properties of cementless concretes after drying and firing has been studied. A substantial increase in the thermal stability of concretes based on a chamotte — quartz binder suspension has been achieved by replacing fine (up to 2 mm) chamotte fillers in their composition with materials with a low temperature coefficient of linear expansion, such as SiC or cordierite.
