High strength grouting material need what to problem note when pouring

High strength grouting material manufacturer high strength grouting material density high strength grouting material model 201 prestressed grouting material fluidity 5 years formal summer, the weather in Shanghai and many degrees of temperature, at the same time of high temperature began to spread, how to carry on the grouting construction in the heat? What are the problems should pay attention to? High strength grouting material deeply under the hot weather, this is because the temperature of the grouting material is higher. And in many cases the new mixing grouting material caused by evaporation speed increase. These problems related to the grouting material mixing, pouring and curing. High ambient temperature increase water grouting material, a new mixed high strength grouting material temperature, speed up and led to a slump loss and hydration reaction faster, which accelerates the grouting material setting, but long-term strength decreased. In addition, the rapid evaporation may cause plastic shrinkage and cracking, subsequent hardening grout sica grouting material strength grade material for cooling tensile stress is produced. Generally recognize high strength grouting material and how much water ratio, when the evaporation rate is greater than the secrete water rose to the surface when the rate of plastic shrinkage cracks, but has also been observed in a layer of water below also have cracks, and under the condition of dry become apparent. The evaporation rate per hour is more than one. 0 kg / ㎡ plastic crack is easy to appear.
