Ordinary Portland cement results from the calcination of limestone and silica in the following reaction. Limestone + silica (1450oC) = Portland cement + carbon dioxide 5CaCO 3 + 2SiO 2 (3CaO, SiO 2) (2CaO, SiO 2) + 5CO 2 The production of 1 tonne of cement produces tonnes of chemical CO 2, in a reaction that takes place at 1450oC. An

8 Main Cement Ingredients Their Functions. Almost every construction work requires cement. Therefore, the composition of cement is a matter of great interest to engineers. For understanding cement composition, one must know the functionality of Cement ingredients. By altering the amount of an ingredient during cement production, one can achieve the desired cement quality.
Our product process is supported by strict process and product quality control. A passion for accuracy ensures that the line of operations in our plant is at par with strict local and international standards. The process uses high grade limestone that in return gives us high grad Ordinary Portland Cement (OPC).

Type I and II are the most common types of Portland cement in the US. Together, they account for more than 92% of the total cement production. Portland cement, contrary to popular belief, is not a brand of cement, but the most common type which is used as an ingredient in concrete and mortar all around the world.
Ordinary Portland Cement is the most common cement used in general concrete construction when there is no exposure to sulphates in the soil or groundwater. Tiger Cement Limited is one of the best maintained companies for exporting Ordinary Portland Cement from Pakistan and is managed by qualified and expert cement field specialists.
Portland cement is the most common type of cement in general use around the world, used as a basic ingredient of concrete, mortar, stucco and most nonspecialty is a fine powder produced by heating materials in a kiln to form what is called clinker, grinding the clinker, and adding small amounts of other materials.

presence of fluorine during the clinkering process. It was observed in the laboratory simulated production of fluoride cement, that the clinkering temperature is much lower (around 1 170 °C) compared to that for the production of ordinary Portland cement. The other observed differences were attributed to the different mineralogical composition as a
Cement Production Process and Reactions. Each step of cement manufacturing, physical conditions and reactions occurred are explained here. Mixing Clay and Limestone.

2 emission during manufacture of Portland cement clinker Ordinary cement, often called by its formal name of Portland cement, is a serious atmospheric pollutant. Indeed, the manufacture of Portland cement clinker involves the calcination of calcium carbonate according to the reaction: 5CaCO 3 + 2SiO 2 → (3CaO,SiO 2)(2CaO,SiO 2) + 5CO 2
In the cement manufacturing process, most material must be broken, such as limestone, iron ore, clay and coal etc. Limestone is the main raw material for cement production, each producing a ton of clinker needs about tons of limestone, more than 80% of raw material is limestone.

Portland cement is a hydraulic cement, hence it derives its strength from chemical reactions between the cement and water. The process is known as hydration. Cement consists of the following major compounds (see composition of cement): Tricalcium silicate, C 3 S; Dicalcium silicate, C 2 S; Tricalcium aluminate, C 3 A; Tetracalcium aluminoferrite, C 4 AF; Gypsum, CSH 2; Chemical reactions during .
Manufacturing Process of Ordinary Portland Cement (OPC) The manufacturing process of Ordinary Portland cement is made primarily from calcareous and argillaceous materials, such as limestone or chalk, and from aluminium oxide, silica oxide, ferric .
There are four stages in the manufacture of portland cement: (1) crushing and grinding the raw materials, (2) blending the materials in the correct proportions, (3) burning the prepared mix in a kiln, and (4) grinding the burned product, known as "clinker," together with some 5 percent of gypsum (to control the time of set of the cement).

HYDRATION OF CEMENT. It is the reaction (s eries of chemical reactions) of cement with water to form the binding material. In other words, in the presence of water, the silicates (C3S and C2S) and aluminates (C3A and C4AF) form products of hydration which in time produce a firm and hard mass the hydrated cement paste.
