Fosroc Conbextra HF Cementitious Grout Powder (25 kg)

Fosroc Conbextra Tie Rod Grouting Compound — Fosroc Conbextra HF — is a high-flow, non-shrink, cementitious precision grout designed for structural grouting and anchoring in construction projects. It's manufactured by Fosroc, a global construction chemicals company.📌 What It Is Conbextra HF is a ready-to-use cementitious grout supplied as a dry powder that becomes a highly fluid grout when mixed with clean water. It's formulated to flow easily into narrow gaps between structural elements and does not shrink as it cures, ensuring full contact with the substrate. 🔧 Key Features High flowability: Very fluid grout that can fill gaps and voids effortlessly. Non-shrink: Dimensionally stable with controlled expansion to compensate for shrinkage in both plastic and hardened states. High early and long-term strength: Achieves strong mechanical performance after setting. Chloride-free: Safe for use where corrosion of reinforcement is a concern. Suitable for pumping: Can be applied by pumping or pouring. Mixes easily: Just add a measured amount of water — no complex additives needed. Low bleeding/segregation: Maintains uniform consistency. 🏗️ Common Uses Conbextra HF is typically used for free-flow grouting of structural gaps and precision applications such as: Grouting of large stanchion base plates and machinery bases. Grouting joints in precast concrete panels. Anchoring reinforcing steel bars and tie bars. Applications where access for pouring is limited. Pumped grouting where extended flow is needed. 📏 Technical Standards Conbextra HF conforms to international standards including: BS EN 1504-3 Class R4: Structural repair and precision grouting. BS EN 1504-6: Anchoring of reinforcing steel bars. ASTM and U.S. Corps of Engineers specifications for non-shrink grout in many regions. 🧪 Typical Performance (Indicative) Gap thickness: 10 – 100 mm (up to ~125 mm depending on region). High compressive strength: Often 60-77 MPa after 28 days (varies with mix). Hydrogen-free expansion: Helps avoid cracking and voids. 💡 In summary: Conbextra HF is widely used where a flowing, high-performance, non-shrink grout is required to reliably fill and bond structural gaps or anchor steel elements in concrete and machinery bases.
