silica fume 3

Silica fume for wire pole base grout,It can be added to the grout used to grout the base of large utility poles to increase the corresponding properties of the grout.Increased densification, silica ash for commercial concerete particles are fine enough to fill in the pores between cement particles. The dense accumulation of particles can reduce water secretion, reduce the average pore size of the capillary pores, and reduce the amount of water required. Microsilica can get good mixing effect when the dosage is 5%~10%. Improve the grout, BY grout segregation and water secretion performance, after pouring concrete, often produce water from the grout separated from the phenomenon, that is, in the surface layer of the formation of a water film, also known as floating grout, so that the upper layer of grout distribution is not uniform, affecting the quality of construction. Silica fume mixed in more and more, the grout material is more difficult to have been segregation and water secretion. When the replacement rate reaches 15%, the grout slump even if it reaches 15~20cm, also almost does not produce segregation and water secretion; When the replacement rate reaches 20%~30%, the grout will be put directly into the tap water is also not easy to produce segregation. Because of the silica fume on the grout, BY grout segregation and water seepage performance improvement, so that mixed with silica fume grout can be used as a harbour, tunnels, and other underwater works.
