Haisen Chemical developed the new generation of concrete admixtures-polycarboxylate ether-based superplasticizers (PCEs). With a relatively low dosage (0.15–0.3% by cement weight) they allow a water reduction up to 40%, due to their chemical structure which enables good particle dispersion.
Haisen PCE Application
1) PCE is used to produce high performance, high strength and flowable concrete.
2) Dosage of PCE is determined according to the designated concrete mix through trial mixing.
3) PCE is dosed either together with water or after the addition of water. It shows more effective when Poly-carboxylate is dosed after the addition of water.
