Influence of catalyst waste on ceramics and expanded clay lightweight concrete properties

Abstract

Influence of the combined use of catalytic cracking catalyst and milled glass waste on the properties of building ceramics (density, compressive strength, water absorption, porosity) is analysed in the paper. The work contains description of clays, sand, crushed brick, milled glass, Portland cement, expanded clay and the catalyst waste characteristics and also presents physical and mechanical properties of samples. Phase analysis of burned ceramic samples was carried out by the method of X-ray diffraction. Technogenic raw material - used catalyst may be utilised in the building ceramics and expanded clay lightweight concrete production have been determined. About 10% of milled catalyst waste may be applied to the formation mix.
