How to avoid the powder issue of grouting material - Guiyang grouting material manufacturers supply

grouting grouting material manufacturer grouting material model for construction wrong, may cause grouting material on the matter of powder, in order to avoid this situation, we should in construction from the following several aspects: one, the grouting material itself to have better guizhou guiyang grouting material factory price of water retention, avoid severe bleeding in grouting material surface water cement ratio is too large. Starting from cooperate of materials selection, attention should be paid to control the water cement ratio shoulds not be too big, plus the seam an agent don't mix, retarded time to fit. Sand, stone aggregate to fit the national quality requirements, special attention should be paid to 0 in the sand. 315 mm below the particle concentration. & N pedestal grouting material cracking of BSP; Second, the setting time of cement is too long, specific surface area shoulds not be too small, grading shoulds not be too focused. Three, pedestal grouting material scale don't vibrating in the construction process, and prohibit excessive water; After construction also should pay attention to timely maintenance, both to avoid grouting material surface before hardening was washed off the surface water cement ratio of the grouting material is too big, also want to avoid grouting guess of the water lost before the strength of surface layer set up. In this paper, related terms explanation is grouting grouting slurry pressure to the fracture of hydraulic structure foundation, fault fracture zone or building itself, seams, cracks in the engineering. After grouting can progress by strata or permeability resistance and integrity of the building and improve the foundation condition, ensure the safety of hydraulic structures. Water cement ratio water-cement ratio English name: water cement thewire when mixing cement, mortar, concrete used in the water and the ratio of the weight of the cement. Water-cement ratio affect the function, cement slurry rheological aggregation structure of the concrete and its compactness after hardening, therefore in composition data of the given circumstances, water cement ratio is the resolution concrete strength, durability and other main parameters of a series of physical and mechanical features. For some kind of cement is one of the most suitable ratio, too big or too small can make strength, and other functions are affected. Water cement ratio according to the same kind cement fixation. Silicate cement, commonly Portland cement, slag cement is 0. 44. The ash cement, fly ash cement is 0. 46.
