Grouting material fluidity big is not necessarily good1

In choosing grouting material, many users will need big fluidity of CGM grout material products, the demand is greater than 350 mm of fluidity, believes that after the fluidity big, can full access to the basic underlying, reduce the occurrence of voids, the idea of structure more closely, is not actually correct ideas, it is one-sided. If the pursuit of CGM grouting material fluidity big, caused the CGM grout material at the time of use, water consumption increased, plasma bone than increased. CGM grout material pulp in bone proportion increase means the possibility of shrinkage cracking caused by increasing. Due to the large mobility of grouting material, easy to operate, easy to make the workers operation is not standard, instead affects its uniformity; And after grouting material casting molding to the front of the grouting material initial setting, because the CGM grout material slowly sinking under the weight of the aggregate, water floating, floating pulp phenomenon. Grouting material on the surface of the substrate without the presence of the aggregate, turned into a pure water slurry, this case is absolutely no compressive strength. And the strength of the rise is slow, need to the surface, after the evaporation of grouting material can be fully cured, increase the strength of the slow problem. And very prone to surface on the matter of powder. In addition, the aggregate of sinking within the CGM grout material is uneven. In reinforcement project, the need to cooperate with steel skeleton structure reinforcement processing, big fluidity of grouting material in casting process is very easy to appear along the reinforcement in reinforced grouting material under the below the sink, reinforced grouting material was reinforced topside, make the surface grouting material along the reinforcement rib fracture. The problem is very serious. Caulking agent manufacturers in this respect, guangzhou building materials factory has many years of engineering experience, with a number of key engineering projects construction, casting brilliant quality, we have been trying to. . .
