Abstract

The paper examined the changes in properties of conventional castables composed of a mixture of calcium-aluminate cement and chamotte caused by changes in the particle size distribution. Properties of castable with 20 % cement and „as received“ chamotte were compared with castableofparticle size distribution adapted to the calculated distribution using the Andreasen equation. Porosity, water absorption, density and strength of samplesafter three-day curing and samples fired at 1100 °C were examined. It was found that samples with adjustedparticle size distribution gave better results than those prepared with „as received“particle size distribution, especially regarding strength.
