ZM - 1 Aliphatic Superplasticizer

This product is formedby polycondensationof sulfonated acetone and small monomer, characterized by high dispersibilityand non-air entrainment, it effectively improves compactibility of concrete,enhances anti-permeability, and lowers water-binder ratio at the same time toincrease the strength of concrete. It satisfies requirements for first-rateproduct in the Concrete Admixture (GB8076-2008) and the TJS [2005] No.160 Standard and has been widely applied to precast and cast-in-place concrete,reinforced concrete and pre-stressed concrete used in industrial and civilconstruction, water conservancy, transportation, ports and municipalengineering, etc.

I.  Property

1.    Appearance: brownish red liquid

2.    PH value: 11-13

3.    Active ingredient: 28—37%

4.    Density: 1.16-1.25

II.      Main technical performance

1.    Mixing amount: 1.2%-2.0%, water-reducing rate: 18%-25%, slump ofthe concrete mixture can be increased considerably. Bleeding can be reduced toimprove workability of concrete. Excellent molding performance keeps thepre-mixed concrete in good workability after long-term transport.

2.    With the same water-cement ratio, it cangreatly enhance fluidity, cohesiveness, pumping performance and stability ofconcrete and increase mechanical properties of the hardened concrete.

3.    This product can increase strength ofconcrete for 20-50% under the same condition, improve compressive strength andflexural strength of concrete and has good compatibility with other admixtures.Besides used for conventional concrete, it can also be used for high-strengthconcrete over C60 and freezing-thawing concrete over 200 times.

4.    This product is economical and can save10-20% cement with workability of concrete mixture and strength of hardenedconcrete unchanged.

5.    Increase durability, workability,anti-permeability, anti-freezing and rustproof capacity of concrete, improvethe internal structure of hardened concrete and lower water-binder ratio.

6.    It can be combined with other materials toprepare compound admixtures and contains no chlorine salt, having no corrosionon steel.

III.     Usage and precautions

1.    Recommended mixing amount: 1.2-2.0% of thetotal gelled materials

2.    Method for mixing: mixing with concrete andthen stirring; adding this mixture after concrete being mixed with water willbe better. For other requirements, please operate according to provisions inthe Technical Code for Application of Admixture in Concrete(GB50119—2003).

3.    Precaution

(1)   The concrete trial-mix test shall beconducted before using it.

(2)   Please pay attention to the accuracy of test measurementand temperature effect on the concrete performance.

(3)   Enhance the early-stage maintenance onconcrete. It is forbidden to eat.

IV.     Package and storage

1.    This product is non-ignitable, anti-freezingand pollution-free and ensures safety during transport, storage and usage.

2.    Shelf life: 2 years.
