Viscosity Modifier Additive-Plastit® VMA

Plastit VMA organic, viscosity-modifying admixture (VMA) is a ready-to-use, liquid admixture developed for producing concrete with enhanced viscosity and controlled rheological properties. Concrete with Plastit VMA admixture exhibits superior stability, thus increasing resistance to segregation and facilitating placement

Controls bleeding
 Reduces segregation, even with highly fluid concrete mixtures
 Enhances pumping and finishing
 Reduces sagging, helping plastic concrete maintain its shape on slopes and arches
Facilitates production of highly fluid concrete mixtures such as SCC
 Facilitates placement of pervious concrete mixtures
 Superior and predictable in-place concrete properties
 Enhances surface appearance
 Flexibility in mixture proportioning
 Provides concrete stability during transport and placement

 Concrete containing “gap-graded” aggregates
 Lean concrete mixtures
 Concrete as a pumping aid
Concrete as a finishing aid
 Self-Consolidating Concrete (SCC)
 Self-Consolidating Grout

The optimum dosage Plastit VMA to meet specific requirements should always be determined by trials using the materials and conditions that will be experienced in use. The normal dosage range is between 0.4 to 1.5 kg/100 kg of cementitious material

Appearance Colorless liquid
Specific gravity 1.01 ± 0.01 gr/cm3 at 20°C
 Chloride  Nil to BS5075 

Packaging
 Plastit VMA is available in 20 kg containers and 200 kg drums 
Storage
 Plastit VMA has a minimum shelf life of 12 months provided the temperature is kept within the range of 5°C to 35°C
