What is Portland Cement? Portland cement is a generic term used to describe any type of hydraulic cement that is produced by heating a mixture of limestone and clay or limestone and shale in a kiln to a high temperature of 1,450 °C. Then the resulting clinker is ground to a fine powder which is known as Portland Cement.
Portland cement is a hydraulic cement (a binder that remains stable under water) that is used in construction works as a cementing or binding material. It is mostly used to make mortar or concrete. ... The consistency of cement can be determined by checking the flowability of cement mortar on a flow table. Benefits in Construction.
