Résumé

Many industrial waste rich in silicates, such as fly ash, blast furnace slag and fiber glass waste have interesting valorization potential as substitute materials in the formulation of cements. This valorization is a very beneficial alternative which will make it possible to reduce costs, CO2 emissions and depletion of natural resources related to clinker manufacturing. The main objective of this work is to assess the valorization potential of the Algerian fiber glass waste (FGW) in the cement mortars formulation and its impact on the mortar mechanical performance. FGW was collected from Maghreb pipe industry factory in Algeria. It is rich in aluminum oxide (Al2O3), silicon dioxide (SiO2) and calcium oxide (CaO).The incorporation of this waste into the composition of cements has had a positive effect on the mechanical and physical performance of the mortars. Based on various arrangements (combinations), the study highlights the quantitative aspect of glass fibers waste to improve the mortars performance. The obtained results show a beneficial behaviour of the glass fibers waste on the characteristics of the mortars for a content of 5%.
