Silica fume for tower crane base grout

Silica Fume for tower crane base grout is a silica fume specially added to the base grout for tower cranes.Silica ash for grouting material can improve the strength of grout, when the siliceous dust for grouting material and efficient water reducing agent used in conjunction, the micro-silica powder and hydration product Ca (OH) 2 reaction to generate hydrated calcium silicate gel, fill the gaps between the cement particles, improve the interfacial structure and adhesion, the formation of a dense structure, thereby significantly improving the strength of grout. General micro-silica powder dosage of 3% to 8%, can be formulated with compressive strength of 100MPa super-high strength grout.(silica power for grouting material)
