A non-shrink, high-strength, self-leveling, cement-based, polymer-modified, single-component grout mortar.
Applications
- Anchoring steel columns to foundations.
- Installing prefabricated concrete elements.
- Securing industrial machinery (e.g., energy turbines, generators, compressors, pumps) to bases.
- Concrete repair.
- Suitable for indoor and outdoor conditions.
Features and Advantages
- Applicable up to 150mm thickness in a single pour.
- High adhesive strength.
- High compressive strength.
- Non-shrink and crack-resistant.
- Resistant to freeze-thaw cycles.
- Weather-resistant.
- Waterproof.
- No segregation or bleeding.
- Easy to apply with a fluid, self-leveling consistency.
Application
Surface Quality: Surfaces must be clean, smooth, sturdy, and free of dust, oil, grease, rust, mold release agents, detergents, or other adhesion-inhibiting substances. Cracks or voids in floors or walls must be repaired using suitable Aktiwex repair mortars. Wait 3-4 days before applying Aktiwex 405-GH.
Surface Preparation: Remove cement laitance and weakened sections. Ensure surfaces are free of oil, dirt, or rust. Pre-moisten highly absorbent surfaces, but avoid standing water or droplets.
Mixing Process:
- Add 3-4 liters of clean, room-temperature water to a clean container.
- Gradually pour the 25 kg bag of Aktiwex 405-GH powder into the water.
- Mix with a low-speed mixer until homogeneous and lump-free (minimum 1 minute).
- Immediately place the mixed grout. Do not add water or remix after the material reacts.
- The prepared mixture must be placed within 2.5 minutes, depending on ambient temperature and water content.
- For enclosed voids, pour Aktiwex 406-GH from one side to expel air and prevent voids. Use a long rod to guide the flow if needed.
- Pouring Thickness: Apply in single layers of 10-40mm. For small-diameter cylindrical anchors, conduct a preliminary test.
Aggregate Addition (for applications >60mm):
Add 5-12mm diameter aggregate at a 90:30 ratio (material to aggregate) using either method:
- Mix aggregate directly into the grout until homogeneous.
- Spread aggregate on the substrate, then pour Aktiwex 406-GH over it. The self-leveling grout will encapsulate the aggregate, forming high-strength concrete.
