خصائص الطوب الطيني الحراري بعد خلطه مع مخلفات الزجاج

The concrete hollow blocks have traditionally been used as construction materials in Gaza Strip, giving people the wherewithal to construct buildings and keep themselves safe. Nowadays, with the Israeli siege that stopped cement from entering into Gaza Strip, fired clay bricks may be used as an alternative to concrete blocks. The production of fired clay bricks with the incorporation of wastes constitutes a positive way for the brick industry to contribute to a more sustainable construction materials. The advantages are on one hand, a reduction of the clay extraction and, on the other minimization of wastes in landfills. The main idea of this research is to focus on the ability of making fired clay bricks as alternative masonry units to concrete hollow blocks and enhancing their properties by adding waste glass. The physical and mechanical properties of fired clay bricks. Also, the effect of waste glass particle size on the properties of the fired clay brick was studied. The results showed that the firing shrinkage, bulk density, and compressive strength of the bricks increased as the amount of waste glass content increased and firing temperature increased. The apparent porosity and water absorption had the same pattern and they decreased with the increase of the amount of waste glass content and firing temperature. The results also showed that the particle size of waste glass powder was very important and had a significant effect on the properties of fired clay brick; the finest the particle size, the highest the compressive strength. The optimal properties of fired brick were found at 30% content of waste glass and firing temperature at 1100°C. The results also implied that it is possible to make bricks with compressive strength of 96.37 MPa and water absorption of 5.93%. Finally, based on the results of this study, use of waste glass as a brick additive is recommended
