Do you need limestone powder for high speed or high grade roads?
Repair the highway, highway without limestone, but lime powder, is what we usually say of lime.When the limestone is calcined at high temperature, it is quicklime, and after the ball mill or Raymond mill is the lime powder
A friend to study the concrete into the 250 mesh powder filler, the conclusion is that it is best not to use or less use, the amount of 10%-15 significantly reduced the strength of concrete.High speed on the cement label requirements, more sloppy. I am a limestone mining industry technical personnel, limestone mine gravel can be used in the repair of high-speed road, powder does not recommend the use of a large number of.
Raw lime powder in the road is mainly mixed with the soil, layers of compaction roadbed, in order to improve the hardness, strength and other performance indicators
