ZM-4 Polycarboxylate Superplasticizer

This Polycarboxylate superplasticizeris the new-generation innovative and environmentally-friendly product wedeveloped, has excellent slump-retaining performance and certain mud resistancewith high water-reducing rate, good strength and small shrinkage and can bewidely applied to various high-grade and high-performance concrete engineering.

I.  Property

1.    Appearance: transparent and brownish redliquid

2.    Specific gravity: 1.06—1.10(under 20℃)

3.    PH value: 5-7

4.    Active ingredient: 40±2, which can beadjusted according to clients’ requirements.

II.      Main technical performance

1.    High water-reducing rate will greatlyimprove concrete strength, and it is especially applicable to high-strength andhigh-performance concrete of more than C50.

2.    With good dispersibility and self-compactness,it can be used to prepare superfluid self-compacting concrete with differentstrength grades.

3.    Strong corrosion resistance and aging resistanceallow little or no shrinkage to concrete.

4.    Good plasticity-retaining performance allowstime extension of the transport of commodity concrete and the residence at thesite so as to ensure workability of concrete. Its setting time delays comparedwith that of the reference concrete.
