GB50448 - 2015 cement grouting material application technical specifications of the permeability resistance of high-strength non-shrinkage grouting material

High-strength non-shrink grout high-strength non-shrink grout material price. High-strength non-shrink grout material manufacturer high-strength non-shrink grout material permeability resistance refers to the high-strength non-shrinkage grouting material to resist the pressure of water penetration ability, it is decided to high-strength non-shrink grout material technical parameters of high-strength non-shrinkage high-strength non-shrink grout material durability fundamental factors. Reinforcement corrosion and alkali aggregate reaction, freezing and thawing cycle, sulfate corrosion which can cause of high-strength non-shrink grout material degradation (water can infiltrate into high-strength non-shrink grout material inside is broken condition, that is to say, water or directly support in guizhou high-strength non-shrink grout material cause swelling and cracking, or as a spread of corrosive medium in the carrier of high-strength non-shrink grout material inside.
