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.
