8. Waterproof Portland Cement: Waterproof cement is prepared by mixing with ordinary or rapid hardening cement, a small percentage of some metal stearates (Ca, Al, etc) at the time of grinding. This cement is used for the construction of water-retaining structure like tanks, reservoirs, retaining walls, swimming pools, dams, bridges, piers etc.

manufacturing of cement mixing grinding Construction Waste Crusher Construction waste refers to the construction, construction units or individuals to construct, lay or demolish all kinds of buildings, structures and pipe networks, etc., and generate the spoil, spoil, waste, residual mud and other wastes generated during the repairing process.
When cement is mixed with water, a chemical reaction takes place called hydration. Hydration is responsible for the setting as well as the hardening of cement mortar/concrete. Setting is quite different from hardening. In this article, we have mentioned differences between the setting & hardening of cement/ mortar/concrete.
It is manufacture by inter grinding Calcium Chloride with rapid hardening portland cement. Normally, calcium chloride with 2 percentage by weight of rapid hardening cement is mixed. Since Extra rapid hardening cement is very sensitive, concrete should be transported, placed, compacted, and finished within 20 minutes after mixing.
Extra rapid hardening cement is obtained by intergrinding calcium chloride with rapid hardening Portland cement. The normal addition of calcium chloride should not exceed 2 percent by weight of the rapid hardening cement. It is necessary that the concrete made by using extra rapid hardening cement should be transported, placed and compacted and ...

Grinding. The clinkers as obtained from the rotary kiln are finely ground in ball mills and tube mills. During grinding, a small quantity, about 3 to 4 percent, of gypsum is added. The gypsum controls the initial setting time of cement. If gypsum is not added, the cement would set as soon as water is added.

The 3 days strength of rapid hardening cement is equivalent to the 7 days strength of OPC when the water-cement ratio for both the cement is taken to be same. The increased rate of strength is due to the fact that higher proportion of tri-calcium silicate (C 3 S) is contained in RHC along with finer grinding of the cement clinker.
