Silica fume for large pump base group,The main role of this silica ash is to be added to the grout for grouting the base of large pumps and other machines, to increase the grout's water resistance, corrosion resistance and viscosity.Accelerating the hydration of the cementitious material system, the exothermic hydration of the system is greatly increased by replacing an equal weight of cement with siliceous dust for grouting material. Need to control the early hydration exothermic grout project in the selection of materials should pay special attention to this point. Improve the strength of grout, when the silica fume and water reducing agent compound use, can make the grout water-cement ratio down to very low, between the cement particles are silica fume filling dense, grout compressive strength increased. Silica fume grout early strength is good, commonly used in repair works/high-level, playing the degree of mining, wear-resistant, anti-corrosion and other special projects. Water conservancy projects use silica fume high strength grout to improve the impact strength.
