Polycarboxylate as a high-performance water-reducing agent, in the construction industry, which is very wide applications, but also can be used as a dispersant concrete, then we in the production process should pay attention to what time it?
    The first point: we use this product in the production of concrete, we should put them to the blender with water washed away when the water red car if you want to recycle, we should pool their individual design a recovery.
    The second point: control the mixing time. According to the survey indicated that the time we finalized within a half a minute to two minutes, but for those who, when mixed with a large amount of polycarboxylate water reducer, we have relatively less time stirring 10-20 seconds. We also need to be controlled according to the different types of stirring time, generally used may be stirred long time.
    The third point: water reducer stirring when released from reducing effect is very slow. We can process into two at the time assigned, the first one: under water is small, all kinds of cementitious materials will soon wrap the particles, which can cause larger operating current mixer, concrete in dry and hard state; second: is Polycarboxylate water-reducing effect of the release, so you can make good fluidity concrete manifestations.
    The fourth point: if we put a good concrete from the mixer were stirred to come up, the naked eye can be seen dry hard concrete, once falling into the car which you will find has good mobility, this phenomenon is polycarboxymethyl acid superplasticizer exhibited high water reducing rate and low water caused.

Up:None!
