High water reducing rate concrete admixture is suitable for premixing, maintaining fluidity, high temperature slump, low slump and other projects with long construction time. This type of cementitious material can reduce the huge loss of concrete caused by high content of mud concrete, long conveying distance, high temperature and strong adsorption capacity. High water reducing concrete admixture can be used alone if it meets the requirement of water reducing rate. If necessary, when using high water reducing rate concrete admixture, it can be combined with other polycarboxylate superplasticizer, such as high performance superplasticizer, to improve the water reducing rate.
The concrete admixture with high water reducing rate can be completely dissolved in water, while the ordinary powder polycarboxylate superplasticizer can not be completely dissolved in water.
