Comparison of mechanical properties of geopolymers from different raw materials with the addition of waste glass

The combustion of fossil fuels results in creating a lot solid wastes such as fly ash and slag. However, these environmentally unfriendly materials can be used raw material for alkali activation – geopolymerization. Although have been successfully industrial production several decades, its use does not achieve the level potential. Today, to sustainable construction industry, alternative cement has extensively investigated. Geopolymer (GP) is kind that obtained from alkaline activator, it produced or by-products. aim this work was describe improvement mechanical properties alkali-activated binders geopolymers made blast furnace effect addition waste glass three different values feed into GGBFS, impact on (compressive flexural strengths) examined. highest value compressive strength achieved with 20% sample 90th day 58,9 MPa. added form broken crushed particles.
