Glass Powder As Partial Replacement Of Cement In Concrete

Appropriate quantity of glass powder was blended with cement in a separate container and then incorporated into the aggregate matrix mixed earlier.

Glass powder as partial replacement of cement in concrete.

To judge the utility of glass powder as a partial replacement of cement in concrete. This move can serve 2 purposes. Glass is principally composed of silica. Thus 15 percent gp content is recommended as optimum.

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. Once waste glasses are reused in creating concrete product the assembly price of concrete can go down. 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. We are also trying to find the percentage of marble powder replaced in concrete that makes the strength of the concrete maximum.

Firstly stone chips and sand were dry mixed for a minute. At 15 percent replacement of cement by glass powder the concrete gives maximum strength which is about 88 22 percent of the control mix. 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. 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.

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. Mix proportion of concrete is shown in table 6. Use of milled ground waste glass in concrete as partial replacement of cement could be an important step toward development of sustainable.
