High-Strength Repair Grouting Mortar
TC-MRZ
This product is a dry powder composed of polymer, ordinary Portland cement, ultrafine admixtures, expansive agents, ultrafine aggregates, and special admixtures. It is a novel composite material with high adhesion and durability. It is specifically designed for rapid repair, reinforcement, and grouting of concrete structures. Its high strength, high fluidity, and durability make it suitable for repair projects subjected to heavy loads or vibration. It can be applied on damp substrates, ensuring health and environmental protection.
The product's performance indicators meet the requirements of the Q/WTC 001-2025 "High-Strength Repair Grouting Mortar" standard.
Product Features
1. Excellent Mechanical Properties: Bonds firmly to concrete, offers high compressive strength, and provides reinforcement and strengthening.
2. Excellent Adhesion and Low Shrinkage: Bonds securely to concrete without cracking or shedding.
3. Excellent Flexibility and Impact Resistance: Resists deformation caused by external forces, reduces internal stress in the system, and improves the material's adaptability.
4. Chemically Stable: Offers excellent corrosion and weather resistance, including resistance to seepage, salt and alkali, and mild acid corrosion, and exhibits strong adhesion to a variety of materials.
5. Easy to Prepare and Use: Simply add water and mix on-site for use. The product offers excellent workability, resists sagging, and facilitates easy application. Scope of Application
1. Repair and reinforcement of damaged components, beams, slabs, columns, and stairways in reinforced concrete structures.
2. Repair of concrete honeycombs, holes, chipping, weathering damage, and micro-cracks on the surface of concrete structures.
3. Repair and emergency repair of damaged areas on airport runways and highway lanes.
4. Repair and emergency repair of damaged concrete floors in industrial plants.
