Sodium Naphthalene Sulphonate (SNF)
This product is a naphthalene series water reducer with chemical synthesis, conforms to national standards of GB8076-2008 concrete admixtures, it is with high performance as non-air entraining superplasticizer, and also has strong dispersion effect to cement particles and high water reducing rate, to save a large amount of cement, meanwhile improving the compressive strength significantly, has a obvious improvement on the concrete frost resistance, impermeability and other indicators.
Main performance:
-
Recommended dosage is 0.5-1.0%, water reducing rate is 12-25%
-
On the condition of constant water cement ratio, increase the concrete slump value more than 10cm
-
At the appropriate dosage, it can improve the concrete R3, R7, R28 strength 40-60%, 30-40%, and 20% respectively
-
Wide adaptability to cement, suitable for ordinary Portland cements, slag cement, etc.
-
Can be used in combination with other admixture, to produce various features concrete admixture
