Concrete Viscosity Modifier
Key words
Concrete, viscosity modifier, polycarboxylate superplasticizer, tackifier, concrete viscosity modifying admixture
Concrete viscosity modifier refers to chemical admixtures that can increase the plastic viscosity of cement paste and improve the workability of concrete.
Performance advantage
Effectively improve the working performance of fresh concrete and the mechanical properties and deformation properties of hardened concrete. It has the functions of anti-cracking, reducing permeability and improving durability.
Performance characteristics
High cohesion, high fluidity, low shrinkage, high cohesion, good water solubility and stability.
application
It is mainly used to adjust the viscosity of concrete and improve the rheology of concrete; improve the viscosity of concrete by compounding with polycarboxylate superplasticizer, and solve the poor performance of concrete segregation and bleeding.
type
Traditional: Polyacrylamide and cellulose ether based VMA viscosity modifiers
Modified: HPEG, acrylic, acrylamide and other modified viscosity modifiers with both tackifying and low sensitivity.
Application examples
Self-compacting concrete, pumped concrete, etc.
