Valorisation of Dune Sand and Wase Brick Filler in Elaboration of Cellular Concrete: Mechanical and Thermal Properties

The aim of this work is both to enhance the dune sand in the production of lightweight concrete with local resources, but also enhances the performance of the sandcrete by incorporating fines mineral as fines from waste of brick . Different parameters were studied, in which the quantity of substitution of fines in the dune sand, the proportions substitutions of lime in the cement, the dosage of expansive agent. The result shows that it is possible to producing lightweight concrete suited to the hot and arid environment with an acceptable heat insulation and sufficient compressive strength. The greatest introduced porosity and lowest density are reached from composition without lime and with 0.5 % Al.
