| Abstract Scope |
Following the trend of improvement and evolution that the advancement of technology, several sustainable materials arise. From this, the current research develops a geopolymeric mixture with the incorporation of waste glass, given the high strength gain capacity of geopolymer materials, eliminating the need to burn artifacts as in ceramics. Thus, mixtures of SiO2/Al2O3 molar ratios fixed at 3.0 and 3.5 with 10% incorporation of waste glass. Water absorption and mechanical strength to compression tests were carried out. In addition, in order to simulate the exposure conditions of the material, durability tests were carried out through wetting and drying cycles and saline attack, evaluating the loss of mass and mechanical strength. The results of the water absorption test showed that the glass residue considerably reduced the water absorption of the materials, presenting reductions of up to 63%. Durability tests by saline attack showed interactions of the salt with the geopolymer matrix. |
