THE STRENGTH, DEFORMATION AND THERMOMECHANIC PROPERTIES OF CRUSHED BRICK AGGREGATE LIGHT-WEIGHT CONCRETE

Abstract

Appropriate mixtures of brick LWC for wall and ceiling elements were developed for the Hungarian Brick and Tile Trust. Dur main conclusions are the following: The production of wall and ceiling elements is possible from only brick aggregate LWC. The designed LWC mixtures resulted in C4-C12 (B70-B200) concretes and their body density was between 1700-1800 kg/m3. The thermomechanic properties of brick LWC and brick are comparable and the brick LWC is 10-12% better as a heat insulator than is a brick wall. The hardening of brick LWC is faster because of the water absorption of brick aggregate and the elements are transportable one day after casting. The prototype ceiling elements from brick LWC satisfield the relevant Hungarian Standard (MSZ 10798/2). The brick LWC elements are lighter, better heat insulators, have better adhesion with mortar, harden faster and their production is technically developed and economical in comparison to traditional elements.
