Modifying of ceramic mass by Kazakhstan bentonite for the purpose of improvement of structure and physicomechanical properties of front wall ceramics

Abstract

Current trends of construction industry development by the criterion of rational environmental management demand scientific approach on further ensuring production of construction materials with available raw material resources, decrease in labor costs and energy resources. For the purpose of decrease in roasting temperature, sensitivity coefficient to drying, for reduction of energy consumption when drying, and also increases of strength indicators, the influence of bentonite clay for obtaining front wall ceramics was investigated. Rational structures of ceramic composition for the production of ceramic brick by the method of semidry pressing with the use of low-grade loam and bentonite clay were received as a result, influence of temperature of roasting on change of physicomechanical properties of the samples on the basis of the developed structures of composition was investigated, consistent patterns of structure and phase formation of ceramic composition depending on roasting temperature were determined. At the research of physicomechanical properties of the obtained samples, it was revealed that mix modifying by bentonite clay previously activated to nanodimensional particles, led to the increase in crack resistance of ceramic mass, durability increase for 30-40% at the general decrease in temperature of roasting for 100-150oС.
