Products Description
High quality concrete admixture pce is a new generation of Eco-friendly high performance polycarboxylate ether superplasticizer powder developed by our company with EPEG 912 with M.W.: 3000 as main raw material.
Advantages/Characteristics:
1.Polycarboxylate ether superplasticizer powder with solid content: 97% min. (Completely soluble in water. If it is used for ready mix concrete , please add PCE powder to water to get a solution with solid content 20% or 10% before use ).
2.With a good slump retention ability, enhance cohesion, without concrete segregation.
3.With a good dispersion, an excellent adaptability to different cements, and good water-reducing properties.
4.Having a thermostability to 50℃ (fifty degree celsius centigrade).
Technical Principle：
The main chains of the high performance polycarboxylate water reducing agent molecular are absorbed onto the surface of the cement granules, which can effectively hinder the hydration, enhance fluidity retention ability, the branch chains surrounded by the cement granules, play dual roles of steric hindrance and electrostatic repulsion, it is totally different from conventional water reducing agents, so the high performance polycarboxylate water reducing agent has better dispersion and water reducing effect.
