Clinker is a solid material produced in the manufacture of Portland cement as an intermediary product. Clinker is ground to a fine powder and used as the binder in many cement products.
Description:
Our Cement Clinker (EN 197-1 CEM 1 52.5 N) is engineered for high-performance cement production, adhering to international standards. This clinker is characterized by its optimized chemical and mineral composition, ensuring superior strength, workability, and durability in cement formulations. It is ideal for producing Ordinary Portland Cement with high early strength, making it suitable for demanding construction projects.
Clinker cement is the main ingredient in the production of cement. It is formed by heating limestone, clay, and other materials in a kiln at high temperatures, resulting in hard, nodular material known as clinker. When ground with gypsum, clinker produces cement, which is widely used in construction for making concrete, mortar, and other building materials. It is essential for the strength and durability of construction projects.
Clinker consists of various calcium silicates including alite and belite. Tricalcium aluminate and calcium aluminoferrite are other common components. These components are often generated in situ by heating various clays and limestone.
Portland cement clinker is made by heating a homogeneous mixture of raw materials in a rotary kiln at high temperature. The products of the chemical reaction aggregate together at their sintering temperature, about 1,450 C (2,640 F). Aluminum oxide and iron oxide are present only as a flux to reduce the sintering temperature and contribute little to the cement strength. For special cements, such as low heat (LH) and sulfate resistant (SR) types, it is necessary to limit the amount of tricalcium aluminate formed.
The major raw material for the clinker-making is usually limestone mixed with a second material containing clay as source of alumino-silicate. Normally, an impure limestone which contains clay or silicon dioxide (SiO2) is used.
The calcium carbonate (CaCO3) content of these limestones can be as low as 80%. Second raw materials (materials in the rawmix other than limestone) depend on the purity of the limestone. Some of the second raw materials used are: clay, shale, sand, iron ore, bauxite, fly ash and slag. The clinker surface and its reactions in different electrolytic solutions are investigated by scanning electron microscope and atomic force microscopy.
Portland cement clinker is ground to a fine powder and used as the binder in many cement products. A little gypsum is sometimes added. It may also be combined with other active ingredients or chemical admixtures to produce other types of cement including: ground granulated blast furnace slag cement.
Cement clinkers is our first product in our cement manufacturing process. Some of our clients prefer our cement clinkers due to its adherence to stringent quality standards during its manufacture - as a result, they do not have to worry about producing superior quality cement as their end product.
Cement, our main product of our cement manufacturing process, is widely used in various types of construction projects - industrial or domestic alike. Our clients prefer our superior quality cement because of our adherence to quality standards.
