Introduction
Poly-carboxylate (PC) based water reducer is a new generation superplasticizer, mainly used in cement concrete. In chemistry, PC is an organic and polymeric electrolyte. It belongs to a polymer surfactant. It can also be applied in other paste materials such as gypsum products and ceramic products to reduce water content.
PC is a weak electrolyte. It can only be fully dissolved in an alkaline solution. It can complex with cations in cement/water system to control the cement hydration process and thus to reduce the slump loss of concrete. PC achieves its water reducing effect through the yield of electrostatic repulsion and steric hindrance when it is absorbed to the cement particles. It is a much more superior dispersant over naphthalene based or melamine based types as water reducer for cement, gypsum and ceramic materials.
Poly-carboxylate superplasticizer has a very high water reducing capacity. It is a most effective type of water reducer, plasticizer and disperser for use to promote high strength, excellent flowability, pumpability and workability, and efficient dispersion for cement, gypsum and ceramic materials and products.
The broad range of applications of PC today is a result of its unique properties and universality. Comparing to naphthalene and melamine based water reducers, PC has superior characteristics:
- High-efficient water reduction up to 30%
- Excellent stability, providing long working time
- Unique homogeneous plasticizing property,thus preventing segregation and bleeding
- Good disperser for various types of cement and gypsum and minerals.
