A collection of trivia about water reducing agents

1. The basic role of water reducing agent.
　　①Improve the compatibility, slump and fluidity of concrete. ②Improve the mechanical properties of concrete. ③Save cement and reduce cost. ④Improve the durability of concrete.
　　2. The principle of the action of water reducing agent.
　　Water reducing agent does not react chemically with cement, the role of water reducing agent on concrete mainly through the plasticizing effect of fresh concrete, so that the concrete in the case of maintaining the same amount of water, can increase the fluidity or in the case of slump remains unchanged, can reduce the water-cement ratio of concrete. Water reducing agents are mostly anionic surfactants, lignin sulfonates, Cai system, melamine sulfonate formaldehyde condensate, etc., anionic surfactants are more widely produced and used, lower cost, good plasticizing effect.
　　3. Advantages of polycarboxylic acid water reducing agent!
　　Compared with traditional high efficiency water reducing agent such as naphthalene, polycarboxylic acid high performance water reducing agent has many unique technical performance advantages.
　　① low admixture amount and high water reduction rate.
　　②good flow retention of concrete mixes; good compatibility with cement.
　　③Small shrinkage of the formulated concrete, which is conducive to improving the volume stability and durability of concrete.
　　④Environmentally friendly and pollution-free in the production and use process, which is a green and environmentally friendly admixture.
　　Based on polycarboxylic acid water reducing agent, JINDUN CHEMICAL has developed special water reducing agent represented by bright water reducing agent, which not only has the basic properties of water reducing, dispersing and slump preserving of common water reducing agent, but also can improve the defects of concrete such as apparent pores, pockmarks and water lines, reduce the porosity by 80%, and does not affect the strength, and the surface effect is no less than that of clear concrete!
