In this respect, this study aims to use foam glass granulates with open-porosity to produce lightweight self-compacting mortars. GFG were prepared from the glass powder (glass cullet) and foaming agent (limestone) according to current applied process for GFG (at a heat treatment 850 °C during 20min). Then they suffered preparation processes as sand, namely crushing and sieving (0-5mm). After, self-compacting mortars were elaborated with natural fine aggregate (sand) and other mortars with granulated foam glass by sand substitution at volume ratios (0, 30, 50 and 100 %). Rheological characterization tests (fluidity) and physic-mechanical (density, porosity /absorption of water and mechanical tests) were carried out on studied mortars. The results obtained show that open-porosity of GFG-sand, has favored adhesion with cementitious matrix without having the segregation of mortar phases. Also, a decrease in the compressive strength was observed for mortars exhibiting a specific lightness. It should be noted that this latter characteristic is very important in construction especially insulation materialsenPhysic-mechanicalGranulated foam glassArticle
