Chemical Concrete Mortar Admixture Sulfonated Naphthalene Formaldehyde 93%

Product Description:

Sodium naphthalene sulfonate is a high range water reducer, commonly referred to as a super plasticizer, also named Naphthalene Sulphonate Formaldehyde Condensate (short name: SNF, PNS, FDN, etc…)
SNF is made from naphthalene, sulfuric acid, formaldehyde and liquid alkali, through sulfonation, hydrolyzation, condensation and neutralization reaction and then drying to powder. SNF-A5% contains very small chloride. Thus, it meets the requirements of chemical admixture specifications for concrete: ASTM Designation C 494 as a Type F admixture, GB8076-2008 and GB50119-2003.

Features:

The mixing amount suggested is between 0.5% to 1.0% of cementing materials, and this can reduce the cementing amount by 20 to 30%. This product, when mixed with concrete, can keep the strength intact, enabling cement saving by 15 to 20%. Note that the solid content should be 0.7%, and slump will experience an increase of 10cm by mixing the product. It is suitable for high strength, early strength, flowing, prefabricating, prestressing force concretes, etc.

Furthermore, this agent can be mixed with other externally applied agents after the successful completion of pilot devement or laboratory experiment.

Applications:

To provide initial workability especially with low water cement ratio.
To significantly improve the initial workability of site mixed concrete without increasing water demand.
To provide improved durability by increasing ultimate strengths and reducing concrete permeability.
To have high slump retention with early setting time.

Feature:

1. When the concrete strength and slump are basically the same, the amount of cement can be reduced by 10-25%.
2. When the water cement ratio remains unchanged, the initial slump of concrete is increased by more than 10cm, and the water reduction rate can reach 15-25%.
3. It has obvious early strength and strengthening effect on concrete, and its strength is increased by 20-60%.
4. Improve the workability of concrete and comprehensively improve the physical and mechanical properties of concrete.
5. It has good adaptability to all kinds of cement and good compatibility with other types of concrete admixtures.
6. It is especially suitable for the following concrete projects: flowing concrete, plasticized concrete, steam curing concrete, impermeable concrete, waterproof concrete, natural curing precast member concrete, reinforced and prestressed reinforced concrete, high-strength and ultra-high-strength concrete.
