Antifreeze Pump Retarder Sodium Naphthalene Sulphonate Formaldehyde

Antifreeze Pump Retarder Sodium Naphthalene Sulphonate Formaldehyde
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.

Recommended range of dosage
Normal dosage is 0.5-1.2%,the dosage is 0.75%,can make best dosage by test.

Packing
Powder 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.

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.

Matters needing attention
1-First use this product,should make test to make best dosage.
2-When add liquid,please deduce the water in the admixtu
