[Naphthalene superplasticizer] in our lives is more common, that naphthalene superplasticizer and other water-reducing agent so nothing? Then we will give you a detailed introduction:
Naphthalene superplasticizer than other water-reducing agent water reduction rate is higher, GB8076 rules of naphthalene superplasticizer water reduction rate of greater than or equal to 14%, while other water-reducing agent is greater than or equal to 8%. Naphthalene superplasticizer not only has a super-lax function, and can inhibit the loss of concrete slump, is the current research and development of water-reducing agent points. Naphthalene superplasticizer and the different cement have a relatively good adaptability, in the low water ratio is more likely to show its low viscosity and slump adherence function, so it is widely used in Europe and Japan.
In addition, naphthalene superplasticizer has the characteristics of low dosage, high water reduction, low slump loss, good volume stability, no corrosion of steel and other characteristics, its functional quality indicators: low dosage, water reduction high. Solid content of 20% of the water-reducing agent mother liquor, the amount of 1.0% (amount of gelling material), the water reduction rate can reach 26-30%. Has a high price.
