Parex Cable Grout

Parex Cable Grout is a specially formulated Portland cement powder mix designed for the grouting of cables in post-tensioned concrete for EN 446(2007) and CARES Appendix PT10 procedures.

The mix design consists of a blend of fine and ultra fine cements plus a set of synergistic admixtures. The grout powder is packaged in 20kg durable, moisture resistant bags ready for onsite mixing. The material readily mixes with water to produce a particularly fluid flowing grout which will penetrate and fill fine voids within and around the cables then harden without shrinking 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 a powerful corrosion inhibitor 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 PT10.

Uses include:

• Grouting of cable ducts, voids and fine fissures.
• Support of cable anchor plates and ground anchors.
• To provide bearing or contact between structural elements.
• Grouting behind shafts and tunnel linings.
• Underpinning, loose floor and road slabs.StandardsCable Grout has been tested in accordance with the appropriate parts of the following Standards: EN445, EN446, EN447, EN196-1, EN196-3.CARES PT10 certificate number 080706 (copies available on request).
