Anticorrosion beautiful seam an agent and admixture affect the performance of early strength grouting material - Bearing grouting material

Early curtain grouting materials and grouting material manufacturer early strength grouting material price building materials research anticorrosive agent, admixture affect the performance of early strength grouting material basic, and the early strength of grouting material permeability performance of experimental research. Results show that the anti-corrosion beautiful seam an agent, water reducing beautiful seam an agent and fly ash, kuangfen more C35 early strength of composite grouting material of 28 d, 56 d mechanical properties and resistance to chloride ion permeability were significantly better than that of not adding antiseptic beauty seam an agent C35 dual permeability mineral early strength grouting material; And C35 dual permeability anticorrosive early strength grouting material 56 d of the resistance to chloride ion permeability index and C50 dual permeability mineral early strength of grouting material permeability resistance is very close, but also meet the chemical erosion H3, H4 and L2, L3 environment of electric flux index requirements.     In recent years, high-speed rail has achieved rapid development in our country, the biggest characteristics is a bridge the generation of high speed railway development road. Because a lot of Bridges in the corrosive environment, early strength grouting material durability research cause concern about the industry of railway Bridges. Many engineering by improving the early strength the strength of the grouting material to improve the early strength of grouting material durability.     How to enhance early high strength grouting material construction technology of curtain grouting material durability? How to select a variety of material has been our existence question & # 8195;   Experiments to find low strength grade early strength grouting material such as adding fly ash, slag powder admixture, by adding antiseptic beauty seam an agent, water reducing seam an agent, such as plus seam an agent to improve the early strength the basic performance and durability of the grouting material. On the premise of meet the requirement of engineering structural mechanics, by adding the plus the seam an agent to improve the strength of low early strength of grouting material for durable performance, reduce the engineering structure by using high strength grade early strength of grouting material and increase costs.     1, the test results show that the four levels of dual permeability mineral early strength grouting material mechanics performance is good, the chloride ion permeability is low. Adding antiseptic beauty seam an agent C35 early strength of grouting material the cube compressive strength is higher than C35 double mineral early strength grouting material, with C40 dual permeability mineral early strength grouting material.     2, although C35 dual permeability strong anti-corrosion early compressive strength of grouting material and C50 dual permeability mineral grouting material is quite different from the earlier, but its 56 d of the chloride ion dentsu quantity can meet the design structure of use fixed number of year for 100 electric flux of the early strength of grouting material requirements, but also meet the chemical erosion H3, H4 L2, L3 and chlorine salt environment requirement for electric flux.     Therefore, strength low early strength of grouting material after adding anti-corrosion beautiful seam an agent, can have good durability, high performance early strength can be used as resistance to chlorine salt grouting material, used for structures in the bad environment.
