CGM high-strength non-shrinkage grouting material strength secret place - Henan grouting material base

CGM high-strength non-shrinkage grouting material CGM high-strength non-shrinkage grouting material of xi 'an CGM high-strength non-shrinkage grouting material CGM high-strength non-shrinkage grouting material product features & # 8195;       1 - after early strength, high strength casting More than 3 days strength up to more than 30 mpa, shorten the construction period.         Their state field just add water mixing, directly into the equipment foundation, mortar gravity, free vibration of construction, ensure no vibration, long grouting construction.         Micro expansion use for a long time without shrinkage casting body, ensure the close contact with the equipment, and no shrinkage between base and foundation, and the expansion of the appropriate compressive stress to ensure the long-term safe operation of the equipment.           Oil anti-permeability in oil soak 30 days after its strength increased more than 10%, molding, dense, impermeability, adapt to the base oil environmental protection.             The durability of fatigue test 2 million times, 50 times of freeze-thaw environment test intensity has no obvious change.           - good weathering resistance 40℃〜 600 ℃ long-term security using the & # 8195;         Low alkali corrosion strictly control the alkali content of raw materials, applicable to alkaline Aggregate reaction inhibition of requirements engineering. What is the distinguishing feature of CGM high-strength non-shrinkage grouting material: the & # 8195; The strength of the CGM high-strength non-shrinkage grouting material in the final analysis, from gelled material hydration hardening as cement stone. Gelled material after hydration material generated, leaving is not a grain of a grain of cement particle swam toward liquid matrix, but immediately bonded interweave each other, become a three-dimensional network structure, the strength and there is still a deformation capacity of the network structure of the material, on the intersection in a solid key link, which was formed which gave CGM high-strength non-shrinkage grouting material strength - the basic units Gelation. On the part of the intersection of solid direct close contact with a solid, van der Waals force is so powerful that during can be compared with the chemical bonds. But once touch off, that is, don't use of CGM high-strength non-shrinkage grouting material to be able to contact again.       This interaction can be referred to as the solid keys, intersection point can be called a consolidation. In another part of the intersection, there may be a small liquid mediation layer, van der Waals force by the liquid, when stress may be a slow slip.     On u pull, you can disable it ( Disconnect) , on the contrary, if the pressure, regardless of size, can cause damage. In aqueous gelling fundamental influence on strength at the same time, don't suddenly xuzhou high-strength CGM high-strength non-shrinkage grouting material slightly an important factor, which is the dense particles fill, fill the space to form a high strength is important.     For multiphase material CGM high-strength non-shrinkage grouting material, the microstructure of each component phase of porosity affects the strength of the CGM high-strength non-shrinkage grouting material. General dense and hard natural aggregate, and cement matrix and interface transition zone between coarse aggregate porosity usually decides the ordinary CGM high-strength non-shrinkage grouting material strength.
