Effects of Viscosity Modifying Admixtures on the Workability of Self-Compacting Concrete
Viscosity modifying admixtures (VMA), known as an important component, are water-soluble polymers that can increase the viscosity and cohesion of self-compacting concrete( SCC). This article presents the effect of four different types of VMA on the workability of SCC , which including flowability, filling ability, passing ability and segregation resistance ability of the fresh concrete. The results show that the low viscosity of VMA satisfies the workability requirement of fresh properties of SCC.
