CEMENT GROUTING MATERIAL
Cementitious Grout. This high-performance modified grout features organic and inorganic additives for early high strength, zero shrinkage, and exceptional durability.
Features
-
This product offers excellent workability with self-leveling properties and extended open time, resulting in a smooth, flat finish. It effectively overcomes common defects of traditional mortar, such as unevenness, cracking, peeling, and powdering.
Ideal for emergency repairs, bearing anchoring, and secondary grouting of heavy/precision equipment bases, anchor bolts, and steel-to-concrete joints. It is specifically optimized for high-speed rail, passenger lines, and highway bridge bearing grouting.
- Ensure the substrate is clean and firm, free of oil, dust, and debris; bolts and nuts must be thoroughly cleaned.
- Mix with water at a 1:0.12 – 0.14 ratio until the desired consistency is achieved.
- Stirring Time: Stir for 3-5 minutes for dry-pack/plastic consistency, or 7-9 minutes for flowable consistency to ensure a lump-free mix.
Meets the technical requirements of the JC/T 986-2018 “Cementitious Grout” standard.
Flowability – mm:
| Initial | 30min |
