CGM high-strength non-shrinkage grouting material CGM high-strength non-shrinkage grouting material price CGM high-strength non-shrinkage grouting material construction first aspect: fluidity, fluidity is refers to the new mix of CGM high-strength non-shrinkage grouting material under the action of gravity or mechanical vibration, the ability to flow and evenly compacted fill the template. Fluidity directly affects the size of the construction difficulty and hardening of the quality of the grouting material, if too dry thickened, grouting is forming hard and dense, and easy to cause internal and surface defects such as holes; If the grouting material too thin, after get their grouting material mix proportion, prone to mud and water water buoyancy and quartz sand aggregate sinks such as stratified segregation phenomenon, affecting the quality of grouting material uniformity, forming the compactness.   The second aspect: the cohesion, cohesion sex refers to the new mix of CGM high-strength non-shrinkage grouting material between the composition of the material has a certain cohesion, to ensure not occur stratification and segregation phenomenon, enables the grouting material to maintain the overall uniform and stable performance. The poor cohesion of grouting material, easy to cause the separation of mud and aggregate, easy to appear the phenomenon such as honeycomb, empty after casting. Cohesion sex is too big, and can easily lead to grouting material fluidity, flow to the position of less than construction, can't contact with contact better close-grained, affect water quality.   A third area, water retention, water retention is zhengzhou equipment foundation CGM high-strength non-shrinkage grouting material refers to the grouting material has the ability to keep the internal moisture. Water retention good grouting material in construction process does not produce serious bleeding phenomenon. Grouting with poor water retention in department of c40 high strength grouting material water easy to precipitate from the inside to the surface, in the place where water seepage left many capillary channel, as the interior of the grouting material permeable channels in the future, the problems that affect the durability, easy to frost crack in winter.
