                           003.jpg                           004.jpg



 The main component of CP-53 is micro silica fume which is a kind of ultra-fine siliceous powder body material which is formed by the rapid oxidation and condensation of SiO2, Si gas and oxygen in the air at a high temperature of above 2000℃.



CP-53 is able to fill the pores between cement particles.At the same time, CP-53 generates gel with hydration product and or with alkaline material Magnesium Oxide. CP-53 can be used to appropriately increase water cement ratio, effectively reduce the density of cement slurry; can increase the compactness of cement paste, significantly improve the compressive, flexural, anti permeability, corrosion resistance; can effectively extend the life of using an explicit of the oil and gas wells.
