Abstract

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.
