Technical Information
Product Description

A high performance, expanding, shrinkage compensated anchoring grout. It is formulated to produce a fluid, non-blending, non-shrink grout with extended working time. It contains migratory corrosion inhibitors to provide corrosion protection for highly stressed steel cables, anchorage and rods. Its fluid characteristics allows the product to be pumped through small openings over long distances and placed into relatively inaccessible areas.

Advantages
  • Ready to use, requires only the addition of specified amount of water
  • Easy to pump or pour
  • Controlled expansion
  • Non-shrink performance provides excellent bearing
  • Flowable and self-leveling
  • High strength
  • Excellent cohesive properties
  • Resistant to water washout and dilution by water in wet ground conditions
  • Thixotropic properties reduce material loss in fractured ground
  • Reduced bleeding
  • Improved resistance to Sulphate attack
  • Very low permeability
Compiliance Standard
  • BS 8110, Part 1, Sec. 8, BS 4551
  • EN 445, 446 & 447
  • UNI 8147

Application Information
Instructions for use

Surface Preparation

The area / duct to be grouted should be cleaned with water before the application of grout. Any free water must be drained out. Cable anchorages should be sealed before the duct grouting is carried out.

Mixing

Add one 20kg bag of ESPANSIL CABLE FLOW into 6.5 to 7 Liters of potable water. For mixing small quantity use a slow speed drill fitted with a suitable paddle at 200-300rpm. For mixing large quantity, it is recommended to use proper grout vane mixer. Adding more water than the specified limits will result in loss of properties. Mix for 5 minutes till obtaining a homogeneous product, free from lumps.

Application

Place ESPANSIL CABLE FLOW by pouring or pumping into the area to be grouted in a continuous manner and do not allow air pockets to develop. The placing should be within maximum 20 minutes of mixing to gain benefit of the expansion process.

Ensure proper evacuation of air, filling process has to be started from one side till the grout flows at the other side.

ESPANSIL CABLE FLOW can be placed in annular gaps of up to 60 mm in thickness.

Cleaning

All used tools should be cleaned with water before the product cures. Cured materials should be mechanically removed.

Recommendations

For application during summer season, the following precautions should be considered:

  • Use cold water (20-23⁰C) for mixing the grout
  • Try to eliminate application during the peak temperature of the day
  • Mix enough grout that can be produced during the workable time
  • Store unused materials in a covered dry place
  • It is recommended to shade the working area during mixing and pumping the grout
