SNF-A Sodium Naphthalene Formaldehyde Sulphonate Superplasticizer Powder

Product Specification

Sodium Naphthalene Formaldehyde SNF-A is used as concrete additive

Naphthalene series superplasticizer is made of sulfonation, hydrolysis and condensation of industrial naphthalene. Chemical name naphthalene sulfonate formaldehyde condensates, it has a strong dispersion of cement particles. Effectively improve the concrete compactness, enhance the impermeability, at the same time can reduce the water binder ratio, greatly improve the early and late strength of concrete. For the preparation of flow concrete, the cast-in-place concrete and prefabricated components with early strength and high strength requirements have a good use effect, which can comprehensively improve and improve various properties of concrete.

Main technical performance:

1, in the concrete strength and slump is basically the same, can reduce the amount of cement 10-25%.

2. When the water-cement ratio is unchanged, the initial slump of concrete is increased by more than 10cm, and the water reduction rate can reach 15-25%.

3. It has significant early strength and enhancement effect on concrete, and its strength increases by 20-60%.

4. Improve the workability of concrete and comprehensively improve the physical and mechanical properties of concrete.

5. Good adaptability to all kinds of cement and good compatibility with other types of anionic concrete admixtures.

6, especially suitable for use in the following concrete projects: fluid concrete, plasticized concrete, steam curing concrete, impervious concrete, waterproof concrete, natural curing precast concrete, reinforced and prestressed reinforced concrete, high strength and ultra-high strength concrete.

Scope of application

1, admixture factory preparation of various anionic compound concrete admixture.

2, high strength, large volume, large mobility and other kinds of concrete.

Matters needing attention

1. Recommended dosage: 1.2-2.0% of the total amount of cementing material.

2, mixing method: this product and water mixed into concrete mixing use; If the concrete after adding water to add this agent, the effect is better; For other requirements, please follow the relevant provisions of GB50119-2003 Technical Specifications for Application of Concrete Admixtures.

3. Precautions

(1)  Compatibility test of concrete mixture should be carried out before use or when combined with other admixtures;

⑵  Attention should be paid to the accuracy of measurement and the influence of temperature on the early concrete performance in construction.

(3)  Concrete compatibility test should be carried out in advance when cement varieties change or concrete raw materials fluctuate greatly.

(4)  Strengthen the early curing of concrete, this product is forbidden to eat.

Packaging and storage

1. Powder products are made of chemical fiber woven bags, lined with plastic film bags, each bag net weight (40±0.2kg) or (25±0.2kg) or (750±0.2kg), can also be customized according to customer requirements.

2. Powder products should be stored in dry and ventilated special warehouse, products such as damp caking can be crushed or dissolved into water agent use does not affect the actual effect.
