Portland cement properties and varieties

What is Portland cement

Portland cement is one of the main materials used for the manufacture of solutions, concrete, tiles, reinforced concrete products.

 Portland cement, unlike air lime, is a hydraulic binder and gains strength and hardens not only in the air but also when connecting with water.

As a result of firing before sintering the raw material mass consisting of limestone and clay, a clinker is obtained. The most important characteristics of cement depend on the quality of the clinker, which we will consider in detail below. Then, with joint grinding of the clinker and gypsum with or without mineral additives, Portland cement is obtained.
