During the construction of the coarse aggregate particles on the pros and cons of high-strength non-shrink grout material - Yingkou high-strength non-shrinkage grouting material

High-strength non-shrink grout high-strength non-shrink grout material manufacturer high-strength non-shrink grout material price quotations in winter construction of high-strength non-shrink grout material thickness of aggregate level of construction intensity has a great influence. Aggregate porosity is very low, perhaps the capillary system is meet the number of large pore blocking, the aggregate itself no shrinkage and high strength not weak. High-strength non-shrinkage grouting material, however, in the aggregate particles can be seen as an airtight container, this is due to aggregate the slurry around low permeability, and water can't move to the porosity of agile. So when frozen, plumpness reached 91. More than 7% of the aggregate particles will be formed near the mortar damage.       If vulnerable aggregate located high-strength non-shrink grout material surface nearby, the aggregate may be abrupt out rather than near the damaged cement slurry.       Before mixing aggregate dry state of high-strength non-shrink grout material, Qingdao durability of high-strength non-shrink grout material can see, the influence of high-strength non-shrink grout material of gas or not, full aggregate, particularly, large particle size, may cause high strength non-shrinkage grouting material.       On the other hand, when mixing aggregate is not full, or to aggregate after pouring some boring, slurry in capillary string, it is hard to reach from the beginning, unless for a long time in cold climates. High strength without shortening after grouting material from wet, hardening cement than aggregate are more likely to be full, on the one hand is because the water can only be reached through the slurry aggregate appearance, on the other hand is due to construct more smaller slurry capillary attraction. Results the hardening cement slurry are more likely to suffer damage, but can through the bleed air way to make it from damage.       Slurry bleed air does not reduce the freezing of the influence of coarse aggregate particles. Even so, in order to rule out aggregate to cement steel structure near the grouting material is the influence of the durability, deal with air-entraining high-strength non-shrink grout material testing instructions pulp guess aggregate. Therefore conclude air-entraining high-strength non-shrinkage grouting material of antifreezing measures for the assessment of coarse aggregate with high-strength non-shrink grout material critical swell test method.       Aggregate is the soul of high-strength non-shrink grout material, the stand or fall of aggregate resolution quality in construction.
