1. It is mainly used for: anchor bolt of foot bolt, cut and bury steel bar, and the thickness of grouting layer is 30mm, and secondary grouting of equipment foundation is used for the second time. Secondary grouting of equipment foundation with oil resistance requirement is called common grouting material.
2. It is mainly used for: secondary grouting of equipment foundation whose thickness of grouting layer is more than 150mm. Reinforcement and reinforcement of beams, plates, columns, foundations and floor of buildings (the thickness of repair is more than 40mm). Secondary grouting of equipment foundation with oil resistance requirement is called special grouting material for reinforcement project.
3. It is mainly used for: prestressed duct grouting, the grouting layer thickness of 10 mm < delta < 150 mm secondary grouting equipment, gap between Angle steel and concrete grouting strengthening concrete beams, the appellation of concrete crack repair special grouting material.
4. It is mainly used for: precision, large-scale and complex equipment installation; Concrete structure reinforcement and transformation, enhancement, rapid road repair, called high strength non-shrinkage grouting materials.
5. It is mainly used for: special grouting material under high temperature environment, volume stability under high temperature, good thermal shock resistance, equipment has long been at temperature of 500 ℃ high temperature radiation environment, 30 mm thickness of grouting layer < delta < 200 mm based secondary grouting equipment, appellation heat-resistant type grouting material.
6. It is mainly used for: the construction time is short, the strength reaches C20 within 2 hours, and the equipment can be operated immediately.
7. It is mainly used for: grouting needs of large volume, high precision and complex structure equipment, with no dead Angle at the grouting place.With good stability, it is called special grouting material for precision equipment and special grouting material for precision equipment.
8. It is mainly used for: the strength grows rapidly under negative temperature, and it is not affected by frost damage. The anchor bolt is bolted and embedded steel bar is planted. The secondary grouting of equipment foundation with anti-oil requirement is called anti-freezing grouting material.
