Viscosity modifiers are a new generation of rheology modifiers, also known as anti-segregation agents or viscosity modifiers. LEAD® A600 has good compatibility with aqueous solution, and the viscosity of the solution does not increase significantly. When LEAD® A600 is used as a viscosity modifier and anti-segregation agent, it enhances the coherence between concrete components, especially during high-pressure long-distance pumping, and can prevent mortar and aggregate from separating from concrete. At the same time, reducing the laitance of concrete is also of great help to the problem of concrete segregation resistance and improving the quality of concrete structure.
Why is the viscosity modifying agent also called anti-segregation agent
As a rheology modifier, the main function of viscosity modifier is to enhance the coherence between concrete components, especially to prevent the separation of mortar and aggregate from concrete during high-pressure long-distance pumping. Therefore, viscosity modifiers are also called anti-segregation agents.
Performance characteristics of viscosity modifying agent
1. Minimize concrete bleeding and material separation
2. Can be directly mixed into admixture
3. No effective delay
4. Under long-distance high-pressure pumping, it can effectively prevent segregation and delamination
5. Excellent segregation resistance
6. Good thermal stability and alkali resistance
7. Does not affect the hardening strength of concrete and plaster
8. Good compatibility with other admixtures such as polycarboxylate superplasticizer
9. Make concrete a Newtonian liquid
10. Reduce the sensitivity of the mix to changes in sand and aggregate grades
