Since ancient times, people have used hydrated lime to build houses and high buildings. Today, the massive architectural works and high-rise buildings are constructed more and more. Why appear firm architectural construction? That is cement â??important hydraulic binder in building process, helping to link projects together, forming a solid mass. With modern advanced machines and science, abundant human resources. 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 non-specialty grout. It 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. Several types of Portland cement are available with the most common being called ordinary Portland cement (OPC) which is grey in color, but a white Portland cement is also available.
Cement is a crucial building material used in construction to bind other materials together. It is a powder made from a mixture of materials, such as limestone, clay, shells, silica, and iron ore There are several types of cement, each with its own specific properties and uses. The most common types include like portland 32.5/42.5/52.5
PORTLAND CEMENT TYPE I/II Low Alkali ASTM C150 Mill sheet will be provided upon request. 52.5 and 42.5 Monthly capacity: 52.5 - 150000.0 MTs 42.5 - 500000.0 MTs
Type 2 OPC cement, a variant of Portland cement, possesses moderate heat of hydration and sulphate resistance. Its balanced properties make it suitable for general construction applications, providing durable and stable structures in environments with moderate sulphate exposure. Pozzolan cement is a blend of Portland cement and pozzolanic materials, such as fly ash or silica fume. It enhances concrete properties by improving workability, durability, and reducing heat of hydration. Pozzolan cement offers sustainable construction solutions and reduces the environmental impact of concrete production. Clinker Cement clinker is the intermediate product produced during the cement manufacturing process. It consists of finely ground materials, such as limestone, clay, iron ore, and shale, heated to high temperatures in a kiln. Clinker forms the basis of various types of cement when combined with gypsum and other additives.
