Experimental Study of the Effect of Partial Replacement of Cement with Glass Powder on Concrete Properties
This experimental research aims at investigating the possibility of utilizing local glass waste in the production of concrete for construction. Experimental program is conducted to study the effects of using glass powder (GP) obtained by crushing of local glass waste as partial replacement of cement on the fresh and hardened properties of concrete. Five percentages of GP were used: 0%, 10%, 15%, 20%, and 25% by weight of cement. For all concrete mixes, slump test was made for fresh concrete and tests were made for hardened concrete to evaluate compressive strength, splitting tensile strength and flexural strength. The experimental results show that workability increased by increasing GP content. Concrete compressive strength was reduced for all mixes with glass powder, but is improved by time. The positive effect of using GP as cement replacement extends to 20% on concrete tensile strength. The results showed that as the amount of GP increases the flexure strength. The use of 20 % glass powder as cement replacement decreased concrete compressive strength by 3.2% at 56 days, achieved better tensile strength at 28 days, increase flexure strength by 18.6% at 28 days and showed good performance compared to all other mixes.
