Double layer packaging with inner plastic film and outer woven bag, 25kg or 40kg each; Liquid: in iron drums, 250kg per barrel; Rain proof and moisture-proof, place in a ventilated and dry place. The validity period is three years, and it can still be used after passing the concrete test.
Discipline: Water Conservancy Science and Technology (first level discipline); Engineering mechanics, engineering structure and building materials (secondary discipline); Building materials (water conservancy) (tertiary discipline).
usage method:
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.
Characteristics of naphthalene water reducer:
1. The main components are β - Cai sulfonic acid formaldehyde condensate, sodium sulfate ≤ 5% and 10%, 18% and 23%. four
There are 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.
