What is the difference between pressure slurry and the filling material

What is the difference between pressure slurry and the grouting material is necessary to strictly control before the construction of the grouting material and mud. Water/cement ratio and water/cement ratio should be associated with the normal use of products and product features. Share of grouting material and water mix in 13. 5 - 14 ( Add water) 。 Water addition should be based on product's width, length and grouting layer manipulation. In general, add water activity, less water, intensity is small. According to the specification and water but also necessary. Pressure slurry mixing ratio is commonly 0. 28. The share is not enough to manipulation of the grouting material. Claim construction company things ready before mixing amount, and formulate precise share. Construction method: mix 1 for a long time. When mixing cement grouting materials, should add water according to product requirements. 2. Cement-based grouting materials should be mechanical mixing. About 3 min and mixed two-thirds water mixture, and for the rest of water, mixing evenly. If the product have a mixture of special requirements, should be mixed according to the requirements. 3. Mixing address should be close to the grouting. This is the construction of mixing way to directly refer to. Why do we need to add water to 2/3? This is due to chemical reaction in water in the grouting materials to reach the function of grouting materials, they are used in transpiration. Transpiration is mainly must strength the grouting materials arrived. In addition, 20% of the water be used to reflect water, 80% of the water used for evaporation. Grouting the seam an agent mixing technology requirements ( 1) Construction equipment cleaning: clean the equipment should not have residue, after water, the filter on the mixer Spaces should be less than 3 mm * 3 mm. （ 2) Slurry mixing operation order: first in the mixer mixing water consumption of 80 - to participate in practice 90%, start the mixer, evenly to all pressure slurry, and while mixing, mixing again after all powder for 2 min, finally take part in the 10 - allowance The mixing water, 20% for mixing 2 min can be used. （ 3) Motion experiment: every 10 plate motion experiment testing on a site, its activity meets the requirements, can enter the store through filter material tank, slurry in the material storage tank should be continued for mixing, in order to ensure the activity of the slurry. （ 4) Under normal circumstances should not rated water add activity in construction process.
