It offers high strength development allows early tensioning of cables.

Details

Fosroc Conbextra CB Grout is a highly flowable high strength grout which can be used for various void fill applications including, backfilling behind concrete tunnel segments, bottom up cable bolt grouting applications and general civil applications. It offers high strength development allows early tensioning of cables. A gaseous expansion system compensates for shrinkage in the plastic state, and it has excellent pumpability over both flowable and thixotropic consistencies.

Features:

  • High strength development allows early tensioning of cables
  • Gaseous expansion system compensates for shrinkage in the plastic state
  • Develops early high strength without the use of chlorides
  • Excellent pumpability over both flowable and thixotropic consistencies
  • Ideal for:

  • Various void fill applications including backfilling behind concrete tunnel segments
  • Bottom up cable bolt grouting applications
  • General civil applications
  • APPLICATION

    Surface Preparation:

    Ensure holes are clean and free from debris. Install cable taking care not to kink the breather tube in the process. Ensure grout tube is correctly positioned and secured at the bottom of the hole. It is recommended to flush water through the grouting lines and up the hole to provide lubrication and to prevent water being absorbed into the strata.

    Mixing:

    A forced-action mixer is essential. Larger quantities will require a high shear vane mixer. Do not use a colloidal impeller mixer. For a thixotropic consistency, use 3.85 - 4.35 litres of water, or for a flowable consistency, use 4.35 - 4.75 litres. Slowly add Conbextra CB powder. The total contents of the Conbextra CB bag should be slowly added and continuously mixed for around 3 minutes. If powder addition is too fast, large lumps will Form and final mix will be slow reaching uniformity. Mix until lump free.

    Placement:

    Continuous flow of grout is essential, therefore ensure that sufficient grout is available to completely fill the hole. Stop pumping when air ceases to bubble out of breather tube. Ensure grout tube is folded and tied off to prevent seepage from the hole.

    Clean Up:

    Remove from tools and equipment immediately after use with clean water. Cured material can be removed mechanically.

    Storage:

    Shelf life of 24 months if kept in a dry store in sealed bags.

    Yield:

    15 kg bag will yield approximately 9 - 10 litres.
