Parex Cable Grout

CARES approved 1-part cementitious grout for grouting of cables in post-tensioned concrete.

Parex Cable Grout is a one-part, cementitious, fluid, flowing grout which will penetrate and fill fine voids within and around the cables, then harden without shrinkage to give a high strength product. Particular advantages of the product include quick and easy mixing with water producing a flowing mix which promotes penetration into confined spaces. The grout is shrinkage compensated and contains powerful corrosion inhibitors to protect the cables.
Once hardened and cured, high compressive strengths are achieved giving resistance to static and dynamic stresses. Parex Cable Grout has a total chloride, sulphate and sulphide-ion content below that specified in EN 447 and CARES PT 10.

  • Shrinkage compensated.
  • High early compressive strength.
  • Excellent flowability.
  • Contains corrosion inhibitors.
  • CARES certified to PT 10: Pre-bagged grout complying with the requirements of BS EN 445, 446 and 447.

Yield

Application steps

MIXING

Measure the appropriate amount of water to achieve the desired grout consistency. For each 20kg bag of Parex Cable Grout, a maximum of 7 litres of water is required. For single bag mixes, suitable mixing may be achieved using a high torque slow speed drill with a grout stirrer. For larger mixes use a standard grout mixer such as the Groutmaster, Putzmeister or Colcrete series. Pour the required quantity of clean water into a clean mixing vessel. Slowly add the Parex Cable Grout to the water whilst continually mixing. Keep the mixed grout in a slow agitating holding tank prior to placing.

APPLICATION

Where Parex Cable Grout will be pumped into place, the grout pump should be of the positive displacement type capable of generating at least 10 bars of pressure. Up to 40 bars may be required to fill particularly long or high upward running ducts. The rate and continuity of placing should be controlled to encourage good penetration of grout into the voids within the duct and the expulsion of air from the duct. Do not disturb once grouting has been completed before the grout has hardened. Parex Cable Grout may be placed at temperatures between +5°C and +35°C.

 

CURING TREATMENT

After grouting has been completed, or when the formwork is removed, any exposed grout must be cured immediately with Sikafloor® ProSeal. During adverse weather conditions, such as high temperatures and drying winds, a second application of Sikafloor® ProSeal should be applied after the first application is dry.

CLEANING OF EQUIPMENT

Clean all tools and application equipment with water immediately after use. Hardened / cured material can only be mechanically removed.
