Experimental Investigation on the Effect of Cement in Abrasion Resistance and Microstructure of Glassrubcrete

Rubber concrete is a new construction materials which is widely used in material science and civil engineering works. Most countries around the world already device ways of recycling wastes products to partially replace and conserve natural resources used in producing concrete. This paper give the performance of glass rubber concrete subjected to chemical resistance. Cement, water, fine sand, gravel, crushed glass of 4.75 mm and shredded tyre of 19 mm were used as partial replacement in the composition of mix ratio of 1:2:4 with 0.50 water/cement ratio. 0% was the control and partial replacement was 5%, 10%, 15% and 20% by volume. Grade 25 concrete in (100x100x100) mm cube was produced and cured for 28 days. Physical, chemical properties, compacting factor test, density, abrasion resistance and SEM-EDS were carried out. Results show that compacting factor (CF) decreases gradually and 5% partial replacement produced high resistance to abrasion. Therefore, rubber glass concrete shows potential in becoming an additional sustainable solution for waste management.
