Choose size large aggregate can increase the flow of the grouting material degree?

grouting material the size of the void fraction of the particle size is not decided, but aggregate gradation, aggregate gradation, porosity is small. The space between the aggregate particle size is smaller, the more, the more need of cement grout epoxy. The area of the surface area is the surface of each stone. Surface area is large, you need more epoxy grout to package the stones, the smaller the particle size, the greater the surface area. In grouting material practice, according to the site, there may be a graded poor, was making, 2 kinds of aggregate, the dosage of admixture is how all need to do the experiment, the stones of the grain size distribution, find out a best.
