Project on Partial Replacement of Cement with Marble Powder

Project on Partial Replacement of Cement with Marble Powder

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. We are also trying to find the percentage of marble powder replaced in concrete that makes the strength of the concrete maximum.

And it happens fast usually within minutes. The Portland cement sets up and the larger volume of the mixture is locked in place permanently. Can You Slow the Setting Time? Ice water will slow down the setting time of hydraulic cement. You can even freeze the hydraulic cement powder before mixing it to get a few more minutes working time.

A ratio by weight of water, 1 cement, 3 sand, and 3 gravel should make a fine concrete, although a little less water ( by weight) would make stronger concrete. The same by volume ( ie. buckets) is a good ratio as well, 1/2 to 1 to 3 to 3 (or a little less water too much water weakens the concrete, and there will always be some water ...
