Polycarboxylate superplasticizer is one kind of the most advanced water-reducing agents in the world with the most advanced technology, the best application prospect and the best comprehensive performance.
The use of this product as follow:
(1) Prior to the addition, according to the concrete design requirements, the water consumption or sand rate is adjusted experimentally, to find amount of water reducing agent that meet the requirements of slump,strength and condensation conditions;
(2) After determining the amount of addition, determine the appropriate mixing technology and obtain a certain amount of experimental data. The flow performance of the produced concrete be meets the construction requirements, and the concrete strength should have a certain margin coefficient, uniform feeding, accurate measurement, convenient adjustment and adding proportion;
(3) polycarboxylate be added after 0.5 to 1.0 minutes of the stirring water during the stirring process;
(4) During the mixing process, the flow rate of the peristaltic pump is adjusted according to the different equipment and requirements, to ensure the best effect of the product.
You need to spray the mixture of polycarboxylate superplasticizer and concrete immediately.
If the mixed liquid is kept too long, it will not only affect the quick setting performance, but also affect the strength of the concrete.
