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

Abstract

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.
