1. The main components are β - Cai sulfonic acid formaldehyde condensate, sodium sulfate ≤ 5% and 10%, 18% and 23%.  three main types.
2. Good dispersion, good water reduction and early strength effect. It can speed up the turnover of formwork and site and speed up the construction Progress and shorten the completion cycle. It is suitable for concrete with early strength and high performance requirements and other needs Concrete that enhances strength and improves long-term performance.
3. Increase the slump of concrete and improve its fluidity, which is suitable for ready mixed concrete, pumped concrete High fluidity concrete, grouting materials, etc.
4. No air bleed. It is applicable to all grades of concrete under steam curing and natural curing conditions.
5. The reinforcement shall be free of corrosion. It is applicable to precast concrete, cast-in-situ concrete and reinforced concrete in various projects Soil, prestressed reinforced concrete, etc.With Portland cement, ordinary portland cement, slag Portland cement, fly ash Portland cement, etc Good compatibility. Fdn-05 and Portland cement, ordinary portland cement, slag Portland cement Fly ash and Portland cement have good compatibility. Main performance and quality indicators.

usage instruction:
1. The dosage range of blends is 0.5-1.2%. According to the project object and the materials used in the construction process
Select the appropriate mixed dose.
2. FDN powder is recommended in solution. It can be used in a dry state, but be sure to mix with it,The concrete shall be fully mixed.
3. If the product is used by dead water mixing method or post mixing method, the water reducing and dispersion effect is better.
4. This product can be prepared with other kinds of concrete admixtures. It can be mixed with fly ash, ground slag, etc
    The admixture is "double mixed", but the mixing amount shall be calculated according to the total amount of cementitious materials.
5. When the product is used for the first time or the cement variety changes, it shall be based on the materials and construction methods adopted on site Concrete trial mix is required. Adjust the construction mix proportion according to the test results as the guidance of construction mix proportion.
