ZM-5 Retarding Superplasticizer (Setretardersuperplasticizer）

This product iscompounded by water-reducing, retarding ingredients and other ingredients,characterized by good dispersibility on cement particles, high water-reducingrate, retarding and low air entraining content. It does not contain chlorinesalt, without corrosion effect on reinforcing steel and has good adaptabilityto cement. It can be widely applied to foundation engineering, highways, dams,wharfs, commodity concrete and large-volume concrete.

I.  Property

II.      Main technical performance

1.    Mixing amount: 1.2-2.5%, powder mixingamount: 0.6-1.2%, water-reducing rate: 15-25%.

2.    Under the normal temperature, final setting timecan be prolonged for 2-8h.

3.    Under the same mixture ratio and same slump,3d and 7d strength of concrete can be increased by 20-40% and 28d strength by20%.

4.    Under the same strength and the same slump,10-20% cement consumption can be saved.

5.    Light slump loss of concrete, which isbeneficial to transport of commodity concrete and construction of large-volumeconcrete.

6.    With good adaptability to concrete, it canbe applied to all kinds of concretes that satisfy the national standard.

7.    Satisfy GB8076—2008 and TJS [2005] No. 160Standard.

III.     Scope of application

Commodity concrete,pumping concrete, large-volume concrete, pile foundation concrete, pre-stressedconcrete, especially concrete under construction in summer and in hot areas.

IV.     Usage and precautions

1.    It shall be added with mixing water

2.    The setting time can be adjusted accordingto different mixing amount, which can be appropriately increased under hightemperature.

3.    Independent use is not suitable under lowtemperature and it shall be mixed with early strength agent.

V.       Package and storage
