The perfect wet curing to important function that the grouting material craze - Imported grouting material

CGM high-strength non-shrinkage grouting material CGM high-strength non-shrinkage grouting material price CGM high-strength non-shrinkage grouting material manufacturer to the application of grouting material, greatly improving the quality of construction, promote the development of the technology of grouting material. Grouting materials including high strength grouting materials, with large amount admixtures grouting material, flow pumping grouting materials, grouting materials, grouting self-compacting self-leveling material and other modern grouting material. But construction units are often used to traditional construction maintenance experience, not too used to grouting of datong no shrinkage grouting material manufacturers use, grouting material early cracking problem is serious, some new problems for grouting material. Grouting material craze, make its ability to resist environmental harmful medium erosion, lower durability. To the change of the grouting material of proportion of raw materials and this year, is the important reason for the early cracking. But the engineering practice shows that, as long as 'timely and fully' the grouting material for wet curing, can make more efficient control of early cracking. Grouting material need timely and fully wet curing grouting material ontology once water loss, or internal defects in its surface. Early wet maintenance requirements from vibrating screeding to wet curing the early hardening process, the end of the grouting material in water loss. It has water loss if wet curing before, must carry on the processing of the grouting material surface, at the start of the wet curing, grouting material on the surface of basic there is no water loss defects. More and more engineering instance to send a clear warning; Grouting material need early wet curing. Under the same conditions, wet curing the closer to perfect, hardening properties of grouting material is better; Deviation from the perfect wet curing, early cracking of grouting material will be more serious, the lower the permeability performance also. 1, fight (poa pratensis) pulp need timely and fully wet curing. Resistance (poa pratensis) pulp if wet curing, inadequate, not in time in adverse climate environment, permeability performance will be greatly reduced. 2, pumping grouting material need timely and fully wet curing. Pumping mortar grouting material capacity is much, slump, contraction relatively large. C40 grouting material; Henan grouting material which strong 3, the high performance grouting material need timely and fully wet curing. High strength grouting material, high performance grouting material low water-binder ratio, less bleeding, concrete the internal migration is slow. 4, mass grouting material need good wet curing. In minimizing grouting material under the premise of internal temperature rise, maintenance of mass grouting material is a key work. The wet maintenance is the premise of engineering quality, the gold medal quality starts from wet curing.
