Addition of VMA to concrete mix increases the plastic viscosity of concrete and leaves a slight increase in yield point. Yield point is another rheological property of concrete which should also be optimized along with the plastic viscosity in
A commercial powdery viscosity modifying admixture (VMA) and another commercial admixture named polymer emulsion (PE) were used in the mixtures. The infra-red

Viscosity Modifiying Admixture (VMA) for Concrete Countertop Mixes. The following seminar excerpt explains what viscosity modifying admixtures do. VMAs are used to reduce the slump of concrete, essentially performing the opposite
The viscosity and there by cohesiveness of SCC can be modified using Viscosity Agents (resins, colloidal matter). II. Optimum dosage is the minimum dosage of super-plasticizer (SP) that

The water content of PCE was considered during the correction for mixing water. Similarly, a commercial aqueous solution of the high-molecular-weight synthetic copolymer
But there would be a limitation to it. The limitations can be overcome by adding Viscosity Modifying Agent (VMA) with the superplasticizers to improve the dispersion and
