ABSTRACT: The sustainability of a city depends on the
effective and efficient management of its solid waste. Waste recycling channels
mainly process glass bottles for direct reuse. Some of these sectors carry out
the crushing and grinding of end-of-life glass waste for use in civil
engineering without the identification in terms of building materials being
clearly established. The present study therefore aims to determine the
physical and chemical characteristics of glass powders and sands resulting from
the crushing and grinding of glass waste from Grand Lomé in Togo in order to
consider their granular potential. Samples of sand and glass powder from the
crushing and grinding of white, brown and green glass were subjected to characterization tests in the
laboratory followed by analysis of the granular parameters and their modeling
by Weibull’s law. The results show that the powder and the glass sand contain a
high proportion of silica (SiO2) ranging from 69.11% to 70.18% and a
low proportion of alumina (Al2O3) (less than 0.07) and
iron (Fe2O3) (lower to 1.09). These three materials have tight and male graded grain sizes (Cu Cc omogeneous
(k dab Mf 2.1) make these materials probable aggregates for
plaster and coating mortars. Nevertheless, an in-depth study will be
made to determine a suitable formula.
