How do gray cement pavement from the concrete floor from the sand solution: No matter what kind of cause ground from the sand, the total sentence is the strength and hardness of the concrete floor is not enough, then how we can increase the strength and hardness of the ground it, is proud to introduce a BC-type concrete pavement patching material. Cement pavement repair materials Products: Cement pavement patching material is a colorless, transparent, non-toxic, odorless, non-flammable water-based environmentally friendly materials for industrial and civil construction joints in concrete, cement mortar substandard materials, construction methods does not regulate the cracks, sand, pockmarked face and hollowing other quality defects of products developed by the bridge expansion joints potholes treatment, it can deeply penetrate the pores of the concrete surface, through a chemical reaction with the concrete and penetration and its surrounding calcareous chemical reaction, and then from the inside out to enhance the density and hardness of the concrete to prevent the ground from the sand to reach a dusting purposes. How to solve concrete shallow potholes fine hairline cracks called cracking: cracking mostly hexagonal pattern. Depth is less than 10 .. 1.2 broken concrete pavement potholes (1) concrete slab pavement pothole: Located base plate surface crack repair bridge expansion joints, small shape, shallow depth of more irregular shape stripping. (2) pit road sector seams: in between two plates repair damaged joints bridge expansion joints, cracks along the line of broken or bad, the development of fast (also known as the broken edge potholes). (3) Slab Corner potholes: Located base plate plate angle triangular shape development in the corner of the plate. (4) bridge expansion joints potholes: Located on both sides of the bridge expansion joints, the width is about the width of concrete expansion joints installed anchor cry, accompanied by key muscle exposed. (5) the bridge pavement pothole: Located on deck pavement depth of deck pavement layer thickness, irregular shape. Deck repair damaged joints | Meeting to bridge (certified) | joints can be provided by the Department of Road and Bridge Technology Co., Ltd., Henan.
