It contains almost methyl cellulose(MC) of all the performance, your first choice for production of high quality building materials additives.To meet the needs of environmental protection, Our product with high water retention, dispersion, good fineness, good work ability, easy dissolution characteristics.It suitable for dry mortar building, both inside and outside wall putty powder milk (cream), adhesives, caulks, interface agents, coatings, self-leveling agent of new building materials
A cement is a binder, a chemical substance used for construction that sets, hardens, and adheres to other materials to bind them together. It is most widely used material in existence and is behind only water as the planet's most-consumed resource.
Property Kol-rtd m cem can absorb on the surfaces of cement hydrate to inhibit contact with water and on the surfaces of crystal nucleis to prevent their increase. So it can retard hydrating of cement slurry.

White cement
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.
Microsilica (silica fume) is a by-product from silicon metal or ferrosilicon industries, is an amorphous silicon dioxide SiO2. This product reacts chemically with the calcium hydroxide in the cement paste which yields a calcium silicate hydrate gel that significantly enhances strength and durability. The super fine microsilica fills the voids between cement particles creating a very dense, less permeable concrete. White Cement advantages: Sustainability: Solar Reflectance Index (SRI): Floors finished with white or pastel color concrete will have a much higher SRI than floors with gray concrete, therefore they will reflect light better, and generate energy savings for the lifetime of the floors. Reduction of Heat Island effect: By constructing buildings with white concrete roofs or light-colored roof tiles, the Heat Island Effect is reduced from surfaces generating less heat and improved reflectivity. Architectural Concrete: White Portland Cement is ideal for decorative concrete and Architectural Concrete applications, Masonry and Cementitious Building Products. A key advantage of using white cement for these applications is that it provides a base color that can be tinted to custom colors to meet any color spectrum demand.

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
