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.
Description: Portland Cement 42.5N (EN 197-1 CEM I) is a top-grade cement, ideal for a range of general and heavy-duty construction projects requiring strong compressive strength and dependable quality. With a 28-day compressive strength of 48.3 MPa, this cement is perfect for residential buildings, roads, pavements, and other infrastructure applications. It meets international quality standards, providing durability and consistency to ensure long-lasting construction results.

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

We supply the Required Grade and Type of Cement that have been procured from the Top Brands made available to the customers at the required Specification for the best prices in the Bulk quantities required. It is obvious that Cement is a very useful binding substance in construction. The usage of cement over diverse fields of construction has made it a very significant civil engineering material. Cement mixed with water and fine aggregate produces mortar, sand and gravel to create concrete. It is the most-consumed resource and is widely available in the market.
