Glass Powder As Partial Replacement Of Cement In Concrete

Results revealed that the concrete compressive strength was not decreased by the cement substitution after 28 days because of the pozzolanic reaction between glass powders and cement hydration.

Glass powder as partial replacement of cement in concrete.

In this study finely powdered waste glasses fly ash and their combination are used as a partial replacement of cement in concrete and compared it with conventional concrete. Appropriate quantity of glass powder was blended with cement in a separate container and then incorporated into the aggregate matrix mixed earlier. In this project our main objective is to study the influence of partial replacement of cement with marble powder and to compare it with the compressive and tensile strength of ordinary m20 concrete. Once waste glasses are reused in creating concrete product the assembly price of concrete can go down.

We are also trying to find the percentage of marble powder replaced in concrete that makes the strength of the concrete maximum. At 15 percent replacement of cement by glass powder the concrete gives maximum strength which is about 88 22 percent of the control mix. Firstly stone chips and sand were dry mixed for a minute. The glass powder replacement in cement was varied 0 25.

To judge the utility of glass powder as a partial replacement of cement in concrete. Efforts have been made in the concrete industry to use waste glass and fly ash as partial replacement of cement. The concrete mixes using brick or glass as 10 replacement of cement exhibited enhancement in compressive strength about 6 4 7 and 2 0 and 7 2 5 6 and 2 at age 7 28 and 90 days. Mix proportion of concrete is shown in table 6.

To check and compare the performance standard concrete and glass powder concrete. Experiment were conducted on concrete prepared by partial replacement of cement by waste glass powder of particle size 75µm the the waste glass powder was replaced by 10 20 30 and 40 of the binder and the mix design was prepared. Use of milled ground waste glass in concrete as partial replacement of cement could be an important step toward development of sustainable.
