ABSTRACT

The construction sector, particularly in countries bordering the ocean, is faced with a major challenge: effectively reusing waste of all kinds to limit pollution and build structures capable of withstanding the environment's long-term acidity (pH). Using waste glass as a finely ground mineral additive in a mortar is a promising recycling route based on the mechanical-chemical activation method. This article presents the research results into using glass powder, which is very recent and rare, as a partial replacement for sand, with a substitution level of 0% to 10%. This work studies the influence of waste glass powder (wgp) and salt water (sw) on mortar's flexural and compressive strength. The physical properties such as porosity, absorption rate, and their micro mechanical-chemical behaviour were also studied. The experimental results showed that the flexural strength of those with glass sand increased with salt water. On the other hand, the Unconfined compressive strength also increased, so the recycled glass aggregate can be used for producing coatings or self-compacting concrete.
