White Micro Silica (Silica Fume) ZSF 940
● Used in the construction of cement concrete: which can reduce the dosage of cement concrete, eliminating material segregation and improve the concrete strength, enhance the wear resistance and durability, improve corrosion of steel, etc.
● Used in monolithic refractories: which can effectively reduce the water addition, good thixotropy, and low temperature combination effect, is the ideal combination of agent, binder, additives and performance improvement of blending.
● Used in the unsteady casting of ladle: which can be used for high temperature and steel water insulation.
● Used in high alumina brick, magnesia brick, sliding water mouth brick, kiln and other high temperature equipment and other refractory materials: which can improve the products quality grade, acting as other ordinary refractory materials.
