What circumstance with early strength type, high strength grouting material

Early strength type, high strength grouting material type high strength grouting material early strength, high strength grouting material factory to help use the unit more clear understanding of the application scope of different type grouting material, to master more knowledge of grouting material, here we go into more detail about under what circumstances should choose the type of super early strength, high strength grouting material? For the following industries we touched, both the owner and installation company of technical personnel, when meet the following seven kinds of circumstances, it is recommended to use super early strength type, high strength grouting material, put an end to use ordinary grouting material, so as not to appear a series of unnecessary trouble. : civil industrial equipment foundation grouting without shrinkage requirement, especially under the condition of high load and impact delivery charge; Two kind of situations: rolling mill of anchorage steel and aluminium industry, punching machine, wire drawing machine and finishing mill; Three conditions: the anchoring turbine, generator, pump and turbine centrifugal compressor; Four kind of situations: the anchoring H section steel column, steel pipe; Five kinds of situations: the transportation rail, crane rail bolt in the transportation sector, the runway lights; Five kinds of situations: industrial conveyor bearings, pipes, bearings in construction industry; Seven kinds of circumstances: used in coal mine conveyor belt, transmission tower in the energy industry. Meet the above five kinds of circumstance, if use normal grouting material, strength reach, loading too quickly, the intensity of grouting material rise slowly, even after the rise, loss is big, appear section of concrete damage, the serious problem such as craze, cause safety accidents, it is absolutely not allowed.
