CHEMIUM VMA is an ideal novel admixture for self-compacting and prestressed concretes. In parallel to the improvement of pumpability it also achieves high consistence of fresh concrete.

• Possibility of achievement of self compactability for concretes without a very low W/C ratio, not being affected by the quality fluctuations of the aggregates.
• It is added and dosed easily, due to its extremely low viscosity.
• It increases watertightness of concrete, due to the high uniformity of concrete.
• It renders the concrete durable to vibration and pumping.
• It ameliorates the surface texture and finish of concrete.
• It reduces shrinking cracking.

CHEMIUN VMA is added to concrete containing superplasticizer of CHEMIUM range, after mixing raw materials. It is not recommended to premix it with other admixtures.

For normal conditions from 0.1 to 0.3% on cement weight. The dosage depends on the temperature, the quantity and quality of cement and aggregates, the quantity of superplasticizer, the W/C ratio, etc.

CHEMIUM VMA is effective only in combination with superplasticizers of the CHEMIUM range, nevertheless it is compatible with all the admixtures offered by our company, except the SPL range.
