Concrete air-entraining water reducing admixture
1.Improve the workability
2.Lower the concrete surface tension
3.Low-alkali

Good freezing-thawing resisting for concrete air-entraining water reducing admixture

Concrete air-entraining water reducing admixture is developed by our scientific research

staffs with reference to domestic and foreign advanced technology formula.

The technical performance of concrete air-entraining water reducing admixture as follows:

Test item		The factory technical indicators	National standard(first-class)
Water-reducing rate,%		≥15	≥12
Bleeding ratio ,%		≤40	≤100
Air content,%		3.0-5.0	3.0
The difference between the setting time(min)	initial set	-60~+120	-90~+120
	final set
Compressive strength rate,%≥	3days	125	115
	7days	120	110
	28days	110	100
Ratio of shrinkage,%	28days	≤120	≤135
Index of relativ durability,%,200times,≥		90	80
Effect on steel corrosion		None
Outward appearance		yellowish-brown powder
Cement paste fluidity(mm)		200min
Application		Applicable to the port, wharf, water conservancy project, highway pavement, freeze resistance, anti-corrosion and seepage control engineerings require a certain air content of concrete.

This product should be in accordance with the requirements of air content(3~5%), After deploy ,find out the optimum dosage amount of admixture in 0.5~1.5%,water-reducing rate:13~20%.

Advantages

1.This product has characteristics of no chlorine, low alkali,delayed coagulation,low slump loss, etc.

2.Right amount added to the product can obviously reduce the concrete surface tension,improve the workability of concrete, reduce bleeding and segregation, improve the impermeability, frost resistance and concrete durability of harmony and so on.

3.This product in concrete can produce small bubbles that is uniform and stable and not easy to damage.

4.After added to this product ,the thermal diffusion, heat transfer coefficient of concrete is reduced. Can improve the volume stability of concrete and various outdoor durability of structure.

5.Can be used for the preparation with requirements of freezing-thawing resistence, test to

determine slump loss before use or Require manufacturers to adjust.

6.Applicable to the preparation of C20-C50 ordinary concrete, Lean concrete, Hydraulic concrete,

Flow of concrete, Commercial concrete, Especially for concrete engineerings with antifreeze and durability requirements.
