In this study, wasted glasses from structural glass walls up to 45 wt.% were added into clay mixtures in brick manufacturing process. Physical and mechanical properties of clay bricks were investigated as functions of the wasted glass content and the firing temperature. The results indicated that with proper amount of wasted glasses and firing temperature, clay bricks with suitable physical and mechanical properties could be obtained. The compressive strength as high as 26-41 MPa and water absorption as low as 2-3% were achieved for bricks containing 15-30 wt.% of glass content and fired at 1100 degrees C. When the glass waste content was 45 wt.%, apparent porosity and water absorption was rapidly increased.
