RHEOMAC® VMA 450
Rheomac VMA 450 organic, viscosity-modifying admixture (VMA) is a premier ready-to-use, liquid admixture specially developed for producing concrete with enhanced viscosity and controlled rheological properties. Concrete containing Rheomac VMA 450 admixture exhibits superior stability and controlled bleeding characteristics, thus increasing resistance to segregation and facilitating placement.
Features Increased viscosity
- Thixotropic properties
- Improved stability during transport and placement
- Controlled bleeding
Benefits - Reduced segregation, even with highly-fluid concrete mixtures
- Enhanced pumping and finishing
- Reduced sagging helping plastic concrete maintain its shape on slopes and arches
- Facilitates production of highly-fluid concrete mixtures such as Rheodynamic® SCC
- Superior and predictable in-place concrete properties
- Enhances surface appearance
- Uniform appearance in high coarse aggregate content and exposed-aggregate architectural concrete
- Provides flexibility in mixture proportioning
