Products Description
pce concrete admixture superplasticizer is a new generation of Eco-friendly high performance polycarboxylate ether superplasticizer flake developed by our company with EPEG 912 with M.W.: 3000 as main raw material.
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.
Advantages/Characteristics:
1.Polycarboxylate ether superplasticizer flake with solid content: 97% min. (Completely soluble in water. If it is used for ready mix concrete or precast concrete, please add PCE flake to water to get a solution with solid content 20% or 10% before use ).
2.pce concrete admixture superplasticizer 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.
Having a thermostability to 50℃ (fifty degree celsius centigrade).
