9084 06 4 Concrete Admixture Naphthalene Sulfonate Formaldehyde Water Reducing Agent Snf-A

Concrete Admixture Water Reducing Agent Sulfonated Naphthalene Formaldehyde SNF-A

Pns Snf Fdn Sulfonated Naphthalene Formaldehyde Powder CAS 9084-06-4 as Concrete Additives

JF SODIUM NAPHTHALENE SULFONATE POWDER (SNF-A)

Snf Sodium Naphthalene Sulfonic Acid Formaldehyde has a good adaptability to various cements and it is no erodent to reinforcing bar and nonpoisonous and pollution-free. SNF has been applied to the highway, bridge, tunnel, water conservancy hydroelectric project, port, quay, skyscraper, power engineering, industrial civil building, prestressing force component and high range concrete etc.

Product Performance Characteristics:

1. The product has a high water reduction rate of 15-30% and can significantly increase the strength of concrete at various ages.
2. Adding this product with the same construction conditions and design strength can save 10-20% of cement.
3. It has good adaptability to Portland cement, ordinary Portland cement, slag Portland cement and fly ash Portland cement.
4. It can significantly improve the durability of concrete impermeability and antifreeze.
5. Low alkali content, per cubic meter of concrete (the amount of cement is 400KG), the alkali content (combined Na2O) increased by adding this agent is less than 1KG.
6. In accordance with the use of aliphatic water reducing agent and sulfamate water reducing agent, the effect and plasticity of the product are obviously improved.

SNF/ NSF/PNS/FDN Usage:

SNF produces concrete with extremely workable characteristics referred to as high slump.
SNF also allows concrete to be produced with very low water/cement ratios at low or normal slumps.
SNF is ideal for use in pre stress, precast, bridge deck or any concrete where it is desired to keep the water/cement ratio to a minimum and still achieve the degree of workability necessary to provide easy placement and consolidation.
SNF will also fluidize concrete, making it ideal for tremie concreting or other applications where high slumps are desired.
SNF is compatible with Portland Cement, Normal Portland cement, Portland Slag Cement, Fly-ash Cement, Portland Pozzolanic Cement, etc.

Technical Features & Adaptability:

1. Mixing amount: 0. 5-1. 0% of cementing materials, reducing rate: 20-30%
2. Keeping concrete strength intact & mixing this product, cement saving amount can reach 15-20%
3. Mixing this product 0. 7% (solid content) , slump constant increases above 10cm
4. Adapting to high strength, early strength, flowing, prefabricating & curing and prestressing force concretes etc.
5. The agent can be combined with other externally applied agents if pilot devement or laboratory experiment succeeds.

Packing:

1. Packing: packing in woven fabric bag with plastic inner. Net weight:25kg ±0.2kg or 40kgs±0.2kg.
2.Cautions: Prevented from being torn by sharpended objects while packages are being transferred or delivered.When being contaminated by high humidity or moisture in case of leakage, it can be prepared in prescribed ways for further use without surrendering any effect.
3. It should be stored in a dedicated warehouse that is well ventilated and dry. If be affected with damp, just smash or melt it into solution without any bad effection.
