Transition region is the existence of the micro cracks grouting reinforcement material permeability of the main causes of big - Hebei bearing grouting material manufacturers

Reinforcement grouting reinforcement grouting reinforcement grouting material manufacturer price reinforcement grouting material is the main reason of the transition zone exists intensity difference exists microfracture, its quantity depends on the size and distribution of the aggregate, cement dosage, grouting material validity of water-binder ratio, a new mixed reinforcement grouting material compacted degree, curing conditions, humidity environment categories of the cement grouting material selection and the temperature of the grouting reinforcement material development.     Common grouting reinforcement material, reinforcement after compaction grouting material casting, large particles aggregate to form water around, especially in the case of a large number of exudation, form water sac at the bottom of the coarse aggregate. After that, the cement hydration ettringite and calcium hydroxide crystal production, coarse due to the aggregate surface in urumqi, epoxy grouting material glue water is bigger, so close to the crystallization of the coarse aggregate of these products is relatively bulky crystal, forming more than the cement paste or mortar pore structure.     另外，使用级配不好的骨料来配制加固灌浆料再捣实时易离析。 从亚微观结构层面看界面层可以清楚地看到，骨料下易形成水囊，在相同条件下，骨料粒径越大，水膜越厚。 In this case the formation of transition region due to the differences between aggregate and cement paste deformation, reinforcement grouting material is prone to cracking. That is to say, the grouting reinforcement material before load, transition region has micro cracks exist.     Transition zone characteristics also influence the durability of grouting reinforcement material, prestressed grouting reinforcement and steel reinforcement grouting material generally for reinforcement corrosion of the rebar corrosion rate to a large extent influenced by grouting reinforcement material permeability.
