Chemical Uses:
1. The concrete strength and slump in substantially the same, can reduce the amount of cement 10-25%.
2. In the same water-cement ratio, the concrete initial slump raise more than 10cm water reduction rate of 15-25%.
3. The concrete has a significant early strength, the reinforcing effect, the strength of improved rate of 20-60%.
4. To improve the workability of concrete, improve the physical and mechanical properties of concrete.
5. Good adaptability to various cement, and other various types of concrete admixtures compatibility is good.
6. 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 .
7. 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.
Precautions:
1.The powder is 0.8 ≤ 2% and the liquid is 1.5 ≤ 3.0%.
2.According to the engineering requirements, the dosage can be adjusted after the test.
3.It is generally added to the mixer at the same time as the mixing water. If the lag admixture or concrete is added before pouring, the effect of mixing and plasticizing is the best.
4.In order to ensure the best use effect, it is suggested that the user should determine the optimum content and method according to the specific situation of the project before using this product for the first time or changing the cement variety in the project.
