To improve the durability of CGM high-strength non-shrinkage grouting material - main measures and requirements Hainan grouting material

CGM high-strength non-shrinkage grouting material CGM high-strength non-shrinkage grouting material price CGM high-strength non-shrinkage grouting material manufacturers will stir the large dosage of water as a manipulation of the durability of CGM high-strength non-shrinkage grouting material quality requirements of a symbol, than with a water/cement ratio is more appropriate. Because of relying on the water/cement ratio control cannot solve grouting guess too many slurry, which caused shortened and the negative effect of hydration heat is added. In high-performance grouting guess, cuts in plasma volume, increase aggregate proportion, and improve CGM high-strength non-shrinkage grouting material permeability resistance or resistance to chloride ion dispersion. If control mixing water consumption, and manipulation of the dosage of slurry ( The bone than) , it is possible to meet the requirement of durability from multiple aspects. For low water-binder ratio of CGM high-strength non-shrinkage grouting material should not be commonly beyond 150 kg/m&sup 3; 。 The water-binder ratio in 0. 42 the CGM high-strength non-shrinkage grouting material, water generally should be control in the 170 kg/m&sup 3; The following. Urumqi epoxy CGM high-strength non-shrinkage grouting material; Manipulation of the CGM high-strength non-shrinkage grouting material can manipulate unilateral water grouting guess gelling material dosage, conducive to drop the permeability of CGM high-strength non-shrinkage grouting material, and cut short the quantity, so you must have a higher dosage of constraints. About the low water-binder ratio of CGM high-strength non-shrinkage grouting material gelation materials dosage, the past is always on the high side, and even up to 550 kg/m&sup 3; Above, the main reason is because aggregate quality owe good, so you must put special emphasis on the CGM high-strength non-shrinkage grouting material of aggregate gradation and aggregate grain shape. To stir to cut the intention of the amount of water and cement slurry, main way; 1, selects the outstanding distribution and grain shape of coarse aggregate 2 seam, adding high efficiency water reducing agent, mixed with low ratio of mineral admixtures. 4, falling water solid ratio ( W / S) And the bone than. For CGM high-strength non-shrinkage grouting material on the whole, falling water and stir add component of solid materials, is advantageous in high-performance CGM high-strength non-shrinkage grouting material advocated water solid ratio ( W / S) ≤0. 08. Control the bone than at lower levels, such as low level of CGM high-strength non-shrinkage grouting material in 0. Below 32, high-grade CGM high-strength non-shrinkage grouting material in 0. Below 35.
