Rapid railway little tunnel repair special grouting material The superfine cement grouting material of fujian

CGM high-strength non-shrinkage grouting material manufacturer CGM high-strength non-shrinkage grouting material construction in the downtown railway little tunnel is often more traffic, we often meet the railway little tunnel pavement damage under serious situation, repeated over a period of time under repair will appear this or that problem again, this kind of problem often appeared in the choice of patching materials, so we should how to choose repair materials? Traditional patching material is usually concrete and overall repair effect is general, materials of inferior, low intensity in use after a period of time will appear crack, honeycomb pitting surface problems, such as more than a vehicle traffic in the process of concrete pavement will gradually appear the rutted influence to traffic. Railway little tunnel construction site of new building materials grouting material will solve this problem, the grouting material is special high strength cement grouting material in tons for combining the seam an agent, selected for aggregate high strength material, supplemented by high flow, micro expansion, made from materials such as anti segregation. （ 1 day 22 or higher compressive strength & # 12316; 27 mpa, three days compressive strength p 38 & # 12316; 45 mpa, 28 days compressive strength of 70 mpa or higher) or higher It is enough to show the superiority of grouting material material construction, is beyond than concrete. New building materials, grouting materials in the future will gradually applied in the anchor bolt anchorage, runway gusu brand grouting material of robbery, nuclear power equipment is fixed, road and bridge engineering, machine base, steel structure and foundation with mouth, secondary grouting equipment foundation, buried, buried steel reinforced concrete structure and transform, old concrete structure crack control, mechanical and electrical equipment, under the rail and steel structure installation, the static pressure pile engineering pile, wall of zhengzhou where there is selling grouting material structure of thickening and leakage of water seepage repair, various foundation subsidence grouting and various repair engineering such as grouting material life is far greater than traditional concrete in the later development will enter more areas.
