Viscosity Modifying (+ consistence controlling)
Viscosity modifying admixtures (VMA) for Self-compacting concrete …
Self-compacting concrete (SCC) is a very high fluidity concrete that uses special mix designs and superplasticizers. With a low fines content in the concrete it may also require a Segregation Control or Viscosity Modifying admixture (VMA) to prevent settlement within the mix.
