MVN Powder CGA-5
MVN Powder CGA-5 is a ready to use injection aid in powder form. MVN Powder CGA-5 causes the cement mixture to expand in whole setting stage. 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

WHERE TO USE
MVN Powder CGA-5 is a special product for the grouting of pre-stressing cable ducts. The use of MVN Powder CGA-5 in the grouting mixture has the following effects:
- Workability retention.
- Good strength and adherence properties.
- Protective action against corrosion of the pre-stressing wires.
- Durable and dense filling of all cavities
MIXING AND APPLICATION
Preparation
- Clean all substrate surfaces free from dust and loose particles.
Mixing
- Add directly to the water and mix with cement.
- The mixture must be stirred continuously.
- For pre-stressed grouting work, batching of mixture is done in mechanical way, mixing time from 3 – 5 minutes together with a W/C ratio 0.40 – 0.45 %. General mixing sequence is Water – Cement – MVN Powder CGA-5. It is not recommended to add sand for pre-stressed grouting work.
- When grout containing sand is to be used the mixing sequence should be Sand – Cement – MVN Powder CGA-5 – Water
Placing
- Place the grout mixture within 15 minutes after mixing. The placing should be un-interrupt until completion
HEALTH AND SAFETY
- During use, avoid inhalation of dust and contact with the skin and eyes. Wear suitable clothing, gloves, eye protection and respiratory protective equipment.
