quarry dust at 0%, 5%, 10%, 15%, 20%, and 25% replacement levels. Three cubes were cast at each replacement level and the average compressive strength gotten at a given curing age. The curing of the concrete was by complete immersion in water. Table 1 below shows the batching of the materials at different replacement levels.

Now place the sand pouring cylinder on the calibrating container and open the slit hole to drop the sand in the container. Once the sand fall has over, close the slit & remove the cylinder. Now the sand has filled over the calibrating container in a cone shape. Now take the weight of the cylinder, which contains the remaining sand as W 2.
