Know the workability of grouting material - Gravity of mortar and grouting material

grouting material manufacturer early strength grouting grouting material usage the workability of grouting material is actually a name of a comprehensive technical index, workability mainly include liquidity, cohesion and water retention. Workability mainly measure the quality of construction and operation of grouting material performance, to put it bluntly workability is the quality of grouting material workability is sailing.     Liquidity of grouting materials related to the cement paste rheological parameters. Casting conditions also affect concrete grouting material workability. Good workability of concrete grouting material should be neither exudation or segregation. Concrete grouting material unit water consumption is larger, the greater its slump.     Mixed with water reducing beautiful seam an agent and air-entraining beautiful seam an agent grouting material workability of concrete is greatly improved, and it can realize the big liquidity concrete, pumping concrete grouting material and grouting self-compacting concrete grouting material. In general, anyang grouting material factors influencing the workability of concrete grouting material including cement slurry plasticity, coarse aggregate level and the biggest size and high strength grouting material construction technology of distribution, morphology and surface characteristics of the aggregate. Sometimes, concrete grouting material mixing plant or construction unit used more coarse aggregate, water absorption in concrete grouting material slump after the loss is too fast, the unknown situations, tend to think the rg grouting concrete grouting material chemistry and beautiful seam an agent does not adapt with cement. In fact, if added coarse aggregate within 1 ~ 2 h absorbed water, concrete grouting material workability remain normal.
