Between the elasticity modulus and the compressive strength of heat-insulating lightweight refractories there is a close correlation factor which is almost linear. Since the elasticity modulus determined (without breaking the products) by the resonan

An increase in water content from 58 to 60% with a simultaneous increase in the apparent density of the foamed body up to 0.55–0.57 g/cm3 achieves a fluidity which ensures easy and perfect filling of the molds. This can substantially simplify the c
