Cement acts as the binder between aggregates (fine and coarse rocks) in the formation of concrete. While cement makes up only a small percentage of the mix (approximately 12 percent by volume), it is almost exclusively responsible for the resulting CO 2 emissions. In the cement-manufacturing process, raw materials are heated to high …
To make a 1:1:2 ratio concrete mix according to volume batching, one should take one bag of cement (35 litres), 1 gauge box of fine aggregate (35 litres) and 2 gauge boxes of fine aggregate (70 litres). If the water-cement ratio is 0.5, then half of the volume of cement, which is 25 litres of water, should be taken.
