5. 85% Undensified Microsilica Fume Applications
Mainly used in unshaped refractory materials, construction, ceramics, pigments and chemical industrial, etc.
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.
