High range water reducing admixture naphthalene superplasticizer contains 5%, 10%, 18% three different specifications due to different Na2SO4 content. Because of its stable performance, non-poisonous, odorless, non-flammable, non-corrosive to steel bars and much better than Sodium ligno and calcium ligno series product, it is more and more popular in construction industry. The main properties is high-efficient water reducing, increasing cement paste fluidity, and improving concrete strength etc.
Main Specifications:
Appearance: Brown powder
pH: 7-9
Sulfate content: 5-18%
Chloride: 0.3-0.5%
Solid content: 93%
Features:
- The concrete strength and slump in substantially the same, can reduce the amount of cement 10-25%.
- In the same water/cement ratio, the concrete initial slump raise more than 10cm and water reducing ratio of 15-25%.
- The concrete has a significant early strength, the reinforcing effect, the strength of improved rate of 20-60%.
- To improve the workability of concrete, improve the physical and mechanical properties of concrete.
- Good adaptability to various cement, and other various types of concrete admixtures compatibility is good.
- Is particularly suitable for use in the following concrete projects: flowing concrete, plastic concrete, steam curing concrete, impervious concrete, waterproof concrete, nature conservation precast concrete, reinforced and prestressed concrete, high strength ultra-high strength concrete .
- When the loss of a large concrete slump, slump loss of nearly half an hour to 40%.High water reducing rate (15% ~ 25%), not bleed air, small influence on the setting time, and cement adaptability is relatively good, can be used with other complex admixture of, the price is relatively cheap
