SPS-08 is a new generation of Eco-friendly high performance polycarboxylate ether superplasticizer powder developed by our company with DD-908 (HPEG 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) SPS-08 Polycarboxylate ether superplasticizer powder with solid content : 97% min. It is specially optimized for plastification and water reduction of construction chemicals.

2) Having a good thermostability to 100℃ (one hundred degree celcius centigrade).

3) Provides an excellent development of early strength.
(4) With a good dispersion, an excellent adaptability to different cements, and good water-reducing properties.
