- increase of the initial and final compressive and flexural strength.
- increase of plasticity.
- increase of watertightness.
- decrease of shrinking during setting (no cracks)
- reduce of the cement amount.
- increased pumpability, improved pumping properties.
- increase of workability time.

CHEM BV-83, added to the concrete mass and cement mortar causes
- increase of the initial and final compressive and flexural strength.
- increase of plasticity.
- increase of watertightness.
- decrease of shrinking during setting (no cracks)
- reduce of the cement amount.
- increased pumpability, improved pumping properties.
- increase of workability time.
Advantages
- It does not affect the reinforcing steel or other building materials.
- It is non-flammable and non-toxic.
CHEM BV-83 is added to the mixing water in quantities from 0.2 to 0.6% on cement weight. The dosage can be raised, without side effects, after suitable trials. For normal conditions 0.4% on cement weight is recommended (habitual dosage).
CHEM BV-83 is compatible with the range of admixtures offered by our company.
