Naphthalene water reduction comes in four forms: powder, brown yellow powder, liquid, and brown viscous liquid. Double-layered packing with inner plastic film and outside woven bag, each weighing 25kg or 40kg; Liquid: in iron drums (250kg per barrel); Place in a well-ventilated and dry area to avoid rain and dampness. The validity span is three years, and it can be utilized even after passing the concrete test.
Water Conservancy Science and Technology (first-level discipline); Engineering mechanics, engineering structure, and building materials (secondary discipline); and Water Conservancy Building Materials (tertiary discipline). Naphthalene superplasticizer is a non-air entraining superplasticizer produced by the chemical industry.
Chemical name: naphthalene sulfonate formaldehyde condensate, which has a significant dispersion impact on cement particles. For the preparation of big flow concrete, cast-in-place concrete and prefabricated components with early strength and high strength requirements have a strong application effect and may fully improve and improve various concrete qualities.
Usage Method:
1. The dose range for blends is 0.5-1.2%. Based on the project object and the materials utilized in the construction procedure. Choose the right mixed dose.
2. FDN powder is indicated in solution. It can be used dry, but be sure to combine it. The concrete should be fully mixed.
3. The water reduction and dispersion impact is improved when the product is mixed using the dead water or post mixing methods.
4. This product can be made using several types of concrete admixtures. It can be combined with fly ash, crushed slag, etc. The admixture is "double mixed," although the mixing amount must be estimated using the whole amount of cementitious ingredients.
5. When the product is utilized for the first time or the cement variety changes, it must be based on the materials and building methods used on-site. Concrete trial mix is necessary. Adjust the construction mix proportion based on the test results.

Applications of Concrete Naphthalene Water Reducer

It is widely utilized in highways, bridges, dams, ports and wharfs, tunnels, electric power, water conservation, and industrial and civil construction projects, as well as prefabricated components that are steam cured or naturally cured.

Characteristics of Naphthalene Water Reducer:
1. The primary components are β-Cai sulfonic acid formaldehyde condensate, sodium sulfate (≤5% and 10%, 18% and 23%). four. There are three major categories.
2. Good dispersion, water reduction, and early strength effects. It can accelerate the turnover of formwork and site, as well as construction. Progress and shorten the completion cycle. It is appropriate for concrete with early strength, high performance requirements, and other purposes. Concrete with increased strength and improved long-term performance.
3. Increase the slump and fluidity of concrete, making it appropriate for ready-mixed concrete and pumped concrete. High fluidity concrete, grouting materials, and so on.
4. No air bleed. It applies to all grades of concrete under both steam and natural curing conditions.
5. The reinforcement shall be corrosion-free. It applies to precast concrete, cast-in-situ concrete, and reinforced concrete in diverse projects. Soil, prestressed reinforced concrete, etc. Using Portland cement, conventional Portland cement, slag Portland cement, fly ash Portland cement, etc. Good compatibility. Fdn-05 Portland cement, ordinary Portland cement, and slag Portland cement. Fly ash and Portland cement are highly compatible. Key performance and quality indicators.
