Expansible non-slump grouting mortar for fixing of anchor elements, sealing penetrations and defects in concrete structures with XYPEX ADMIX C-1000 admixture

Product Characteristics
A single-component dry mortar expansible mix containing expansive and sealing admixture XYPEX ADMIX C-1000. Meets the requirements of EN 1504-6 for anchoring and reinforcing concrete by steelreinforcing bars.

  • applied manually, it is thixotropic – doesn’t flow down
  • perfect adhesion to base
  • permanently water resistant
  • perfect mechanical properties
  • perfectly fills up holes and cavities due to controlled expansion
  • permanently seals filled holes and connections due to secondary crystallization in pore structure of the mortar and adjacent concrete against water, oil products, etc.
  • enhanced chemical resistance

SUPERFIX XP TH is a single-component expansible dry mortar mix on the Portland cement basis intended especially for anchoring elements fixation and filling up holes and cavities in concrete structures. SUPERFIX XP TH mortar ensures proper and permanent filling and monolithing of the concrete. It provides alkaline protection to anchoring elements. It is also practical for monolithing of joints in prefabricated or monolithic reinforced concrete structures. Filled up holes are sealed perfectly against water and variety of both aqueous and non-aqueous liquids, especially oil products.

Instruction for preparation and application.
Base. Any dust and incoherent particles shall be removed from the base before application. The concrete surface cannot be contaminated by substances, which can negatively affect adhesion of the mortar to the base (oil or other products). Before application of the prepared mortar, humidification of the concrete surface shall be properly and repeatedly performed for at least 120 minutes.

Preparation of mortar. SUPERFIX XP TH is prepared by mixing necessary amount of dry mortar with measured amount of water. The recommended mixing ratio is specified in the Table I. Optimum quantity of batching water can fluctuate in the given interval as it is usual with mortars containing a cementing binder.

Workability of the product is 50 – 60 minutes under 20 °C.
Neither temperature of base nor temperature of ambient air shall be below + 5°C and above + 30°C.

Mortar application. SUPERFIX XP TH grouting expansion mortar was developed especially for small volume repairs of passages and defects in concrete structures. SUPERFIX XP TH mortar can be applied mechanically or manually. Anchoring holes (resp. filled joints, passages and holes in general) shall be filled at once without any interruption so the filling won’t contain work joints.

Applied mortar treatment. Laid surfaces shall be properly treated immediately after completion. Use of the PE foil, moistened geotextile, etc. for coverage of laid areas or filled holes proved well.

Specific consumption
Specific consumption of dry mortar amounts to 1.8 ÷ 1.9 kg/dm3.
