The widely application of the grouting material have what advantages

grouting CGM high-strength non-shrinkage grouting material produce high strength grouting material 1, grouting material is rich in raw material origin, grouting guess accounted for about 80% of aggregate sand, stone, sand, stone for local materials, local materials for moderate price. 2, mixing grouting material has excellent plasticity, according to the construction plan of the grouting material to reinforce the requirement of the engineering structure pouring into various shapes and grouting material structures of arbitrary size. 3, manufacturing flexibility and good adaptability. By changing the proportion of the grouting material composition material and variety, it can be made of different physical and mechanical properties of grouting material, to meet the needs of different projects. 4, high compressive strength. Grouting material its compressive strength after hardening in 20 ~ 40 mpa commonly, can be as high as 80 ~ 100 mpa, which is very suitable for used as structure materials. 5, and have very good bond between steel bar, and grouting material and reinforced basic same, linear expansion coefficient of the composite reinforced grouting material, can guarantee to work together, and then greatly expanded the use of grouting material. 6, good durability. Under normal circumstances, the grouting material does not need special protection and maintenance, low cost of protection. 7, good fire resistance. Fire resistance of grouting material is far better than wood, steel and plastic, can a few hours of high temperature resistant effect and still maintain its mechanical properties, fire fighting and rescue. With the development of the modern grouting material science and technology, the deficiency of grouting material has been greatly improved. If choose light aggregate can reduce weight of grouting material and improve the heat preservation and heat insulation performance; Grouting guess doped polymer and fiber, greatly improve the brittleness of grouting material; With early strength the seam an agent can advance grouting material such as early strength, shorten the construction period. It is these characteristics of grouting materials, grouting materials widely used in industrial and civil building, water conservancy engineering, underground engineering, highway and railway, Bridges and national defense construction.
