Experimental Investigation of Mechanical Properties and Durability of Sustainable Concrete Using Glass Waste

This research aims to study some of the properties of concrete containing with glass wastes in the fresh state and the hardened state. Concrete mixtures containing glass waste powder (GP) with size less than 0.075 mm as an addition to the cement weight by 10%, 20% and 30%, glass waste fine aggregate (GF) passed through a 1.18 mm Sieve as a partial replacement of sand with the same ratios and also make a concrete mixture containing GP and GF together at a ratio of 20%. Chemical additions and mineral additives were used by 0.6% and 5% of the weight of the cement materials respectively. The results of the research showed that specimens with glass waste have a better workability compared to the control mixture. The compressive strength (fc) of the control mixture reaches 43 Mpa, at the age of 28 days for GF, there is an improvement in fc up to 5% at 10%, above this ratio the strength decreased compared to the control mixture. For GP, there is a decrease in fc compared to the control mixture at all ratios. While at the age of 56 day, there is an increase in fc of GF concrete up to 24.7% and 11.6 at 10% and 20%, respectively, then after which there was a decrease in fc compared to the control mixture. For GP, there is an increase in fc reached 3%, 6.5% at the percentage of addition 10%, 20%, respectively, then a decrease occurred compared to the control mixture. The indirect tensile strength (ft) of the control mixture reaches 3.98 Mpa, ft of GP and GF concrete decreases significantly, reaching 113% and 98%, respectively, compared to the control mixture. For Specimens with GP and GF together with ratio 20%, it was found that there a decrease in fc and ft compared to the control mixture. The porosity and absorption of GP and GF concrete increased by an average of 70% and 90% compared to the control mixture, respectively. The density of GP and GF concrete is lower compared to the density of the control mixture.
