MVN Powder CFA-500
MVN Powder CFA-500 is a ready to use injection aid in powder form, chloride free additive. MVN Powder CFA-500 causes the cement mixture to expand in whole setting state. The expanding is caused by the formation of densely distributed very small gas bubbles. Water reduction and good workability.
FEATURES AND BENEFITS
- Gaseous expansion system compensates for shrinkage and settlement in the setting state;
- Reduce the bleeding from the grout mixture;
- No Chloride and other ingredients of corrosive nature;
- Pumping and injection aid.

- Workability retention.
- Good strength and adherence properties.
- Expansion and Shrinkage compensation.
- Durable and dense filling of all cavities
MIXING AND APPLICATION
Preparation
- Sand used for grout should be cleaned, well grade and dry. If the sand is wet, the moisture of sand should be determined for every batch, or average moisture of every lot of sand should be apply before using.
