PORTLAND CEMENT

Clinker the principle intermediate. manufactured product within cement production is typically produced from a combination of ingredients including. limestone (for calcium) coupled with smaller quantities of materials such as clay iron ore and sand (as sources of. alumina iron and silica respectively).

Gypsum Content - an overview | ScienceDirect Topics

Hydrophobic cement (IS 8043-1991): Hydrophobic cement is obtained by intimately mixing together calcareous and argillaceous and-or other silica- alumina- or iron oxide-bearing materials burnt at clinkering temperature and grinding them with natural or chemical gypsum with a small amount (say 0.1%–0.5%) of hydrophobic agent forming a film which is water-repellant around each cement grain. The film is broken out when the mixing together of cement and aggregate breaks the film.

Clinker is one of the two main ingredients of cement; Gypsum is the other ingredient. Clinker manufactured from limestone after heat treatment is in the form of hard rocks typically 2” in size. Grinding clinker uses more energy as compared to softer materials such as the additive limestone which is not heat treated.

Portland-Limestone Cement

Producers know that replacing some of the clinker in portland cement with ground limestone offers benefits the most important being that it reduces the embodied CO2 of the cement. Modifying a concrete mix design to replace higher carbon materials with lower carbon ingredients is an effective strategy to reduce its environmental footprint.

Portland cement - Wikipedia

Portland cement is the most common type of cement in general use around the world as a basic ingredient of concrete mortar stucco and non-specialty grout. It was developed from other types of hydraulic lime in England in the early 19th century by Joseph Aspdin and usually originates from limestone. It is a fine powder produced by heating limestone and clay minerals in a kiln to form clinker grinding the clinker and adding 2 to 3 percent of gypsum. Several types of Portland cement are avai
