Naphthalene Sulfonate Formaldehyde Condensate Chemical Additive For Cement And Concrete
Product Performance characteristics
- The product has a high water reduction rate of 15-30% and can significantly increase the strength of concrete at various ages.
- Adding this product with the same construction conditions and design strength can save 10-20% of cement.
- It has good adaptability to Portland cement, ordinary Portland cement, slag Portland cement and fly ash Portland cement.
- It can significantly improve the durability of concrete impermeability and antifreeze.
- 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.
- 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.

Scope of application
This product is widely used in building,road,airport,seaport and premix concrete project.
Recommended range of dosage
Normal dosage is 0.5-1.2%,the dosage is 0.75%,can make best dosage by test.
PackingPowder package by plastic bag lined or woven inside,paper bag net weight 25 To 40 kg,liquid used plastic barrel,metal barrel,net weight 200kg,1000kg,Also can be used transport tankers in bulk transport tanker.Transport should prevent moisture,The drum should prevent leakage or evaportation drying.Matters needing attention
Storage conditions and period of validity
Powder should be stored in a dry,ventilated warehouse.When it trun to block in storage,should make it to liquid if passed validity,should test before use. The validity is 2 years.
Method of use
When it is powder,mix well of cement sand and stone then put in water last step in admixture is better.
When it is liquid,put admixture in last step is best one.
1-First use this product,should make test to make best dosage.
2-When add liquid,please deduce the water in the admixture.
1-This is a little alika liquid,no toxic,no corrosion,when torch it,shouldclear in water to hospital when possible.
2-The powder is thickness,please wear mask and glove when use it.
When the admixture is a powder, the cement, sand, stone and admixture are added together to the mixer, and after being stirred uniformly, the mixing water is added and stirred for 2-3 minutes. Conditional lag is better for mixing water.
When the admixture is a liquid, the cement, sand, and stone are added together to the mixer, and after stirring uniformly, the mixing water is added, and the mixture is stirred for 2-3 minutes. Conditional lag is better for mixing water.
1. When the user first uses the product, or when the material such as cement changes, it is necessary to pass the concrete experiment to determine the optimum dosage.
2. When mixing liquid products, the amount of water in the water reducing agent should be deducted from the concrete mix ratio..
Security protection tips
1. This product is a weakly alkaline solid, non-toxic, non-corrosive, but not edible. When it comes into contact with the human body, it should be clear with clear water as soon as possible. If it causes allergies, it should be treated promptly..
2. This product has a fine powder and is prone to dust when used. Wear masks, gloves and other protective equipment.
