Concrete admixture raw material Naphtalene based Superplasticizer
Naphthalene superplasticizer is non-air entraining superplasticizer by chemical synthesis. Chemical Name: naphthalene sulfonate formaldehyde condensates, having a strong dispersion on cement particles and a good use of effects on preparation of the crowd of concrete, in-situ concrete and prefabricate components that requires high-early strength and high strength, fully enhance and improve various properties of concrete. Product Features
1. When the concrete strength and slump are substantially the same time, it can reduce the amount of cement 10-25%.
2. When water-cement ratio is unchanged, raise the concrete slump initial more than 10cm.
3. Significant high-early-strength and enhance effects on concretes, its strength is increased by 20-60%.
4. Improve the workability of concrete, well improve the physical and mechanical properties of concrete.
5. Good adaptability to various cement, and other various types of concrete admixtures good compatibility.
6. Particularly apply for use in the following concrete works: flowing concrete, plastic concrete, steam curing concrete, permeability of concrete, waterproof concrete, nature conservation precast concrete, reinforced and prestressed concrete, high strength and ultra high strength concrete.
