Portland Cement is a hydraulic binder in the form of a finely ground inorganic dark gray powder. When mixed with water, it forms a paste that sets and hardens by means of hydration reactions and processes and which, after hardening, retains its strength and stability, even under water.
Portland Cement, appropriately batched and mixed with water, aggregates and sand, results in concrete or mortar, used widely and universally in the building and construction industry.
There are various kinds of Portland Cement designed for different construction and building specifications. The differences are mainly based on the strengths developed by the cement and the speed with which these strengths are reached.
