Sodium Naphthalene Sulfonate Condensate

1.Physical itemi
Sodium sulphatei 5%max 10%max 20%max (three kinds)
Solid content : light browner powder
Appearance : 92%min
Chloride i 0.3%max
Water inside : 7%max
pH i 7.5-8.5

2.Enhance the effect of the concrete as following:
* 15-20% of cement can be reserved under the condition of the same caving in and same strength
** Non-poisonous, odorless, non-flammable and non-corrosive to steel bars.
* Suit for blend for the C30-C60i 32MPA-80MPA i concrete
* Degree of collapses(Degree of fluidity): 180 mm- 280 mm
* Reducing ratioi 18%-30%
* As the condition of the material and the climate where amount of cement and collapsibility are fixed aforehand, mixing water can be decreased by 18-28% when it is mixed with reinforced concrete at 0.5-1.2%. Statistically, compression strength on the lst day, the 3 rd day and the 28 th day after single application is increased by 60-100%, and 30-60% respectively when it is added at standard blend dosage. The compression strength, tensile strength, buckling strength and modulus of elasticity will be improved.

3. Scope of application
* Apply to Natural curing concrete and aerated concrete
* Apply to compound lean concrete and high strength concrete
* Apply to all types of Portland cement

4. Application method
* The quantity scope to be mixedi 0.4i 1.2i of the weight of cement, better performance will be given if the scope could be controlled by 0.6-1.0%.
