Product details

Silica fume for High-speed railway rpc cover plate ,this kind of silica fume is generally added in the rpc cover plate of high speed railway.Microsilica particle size are less than 1um, the average particle size of 0.1um or so, is the diameter of the cement particles 1/100, so the silica ash rail RPC can be highly dispersed in the concrete, filling in the cement particles and improve the degree of compactness, at the same time, micro-silica fume has a high degree of activity, can be faster and more comprehensive and the hydration of cement produced by the reaction of the oxygen and hydrogen compounds. Mixed into the concrete can be filled between the gaps in the cement particles, so that the paste is more dense, micro-silica powder volcanic ash activity index of up to 110, the effective substitution coefficient of 3-4, Dragon is generated after the hydration of the cement Ca (OH) 2 has a strong absorption, the formation of well-developed calcium silicate gel, and greatly improve the strength of the concrete.
