| 3-day compressive strength: | Mp |
|---|---|
| Operable time: | 1 |
| Place of Origin: | Changsha |
| Functions: | The grouting agent (material) has the excellent properties of micro expansion, non shrinkage, large flow, self compaction, extremely low bleeding rate, high filling degree, small diameter of foam layer, high strength, rust prevention, low alkali and chlorine free, high adhesion, and environmental protection. It contains no oxides, chlorides, sulfites, nitrites and other harmful components of steel bars. It is a kind of grouting agent refined from high-performance plasticizer, surfactant, calcium silicate micro expansion agent, hydration heat inhibitor, migration type rust inhibitor, nano-sized mineral silicon aluminum calcium iron powder and stabilizer or a kind of grouting material refined and compounded with low alkali and low heat Portland cement. |
| Specifications: | 25kg/ bag |
| 28 day compressive strength: | Mp |
| Scope of application: | The grouting material used for filling the post tensioned prestressed pipeline, preventing the anti-corrosion of the prestressed steel, ensuring the effective stress transfer between the prestressed tendon and the concrete structure, making the slurry in the duct full and dense, maintaining a certain pH value range, completely wrapping the prestressed steel, the slurry has higher strength and elastic modulus, expansion, non shrinkage and adhesion after hardening. It is suitable for filling grouting of post tensioned prestressed pipeline, anchoring grouting of ground anchor system, continuous wall head leakage prevention grouting and curtain grouting; equipment foundation grouting, base plate grouting and beam column joints, engineering rush repair and bolt anchoring, no need for vibration, self compaction, micro expansion, oil permeability resistance, corrosion resistance, frost resistance and seepage resistance; it is used for pore grouting of high-strength steel prestressed concrete components, road and bridge girder addition. It can be operated 24 hours after fixation, and it is firmly bonded with hardened concrete, without obvious traces of repair, and the setting time of slurry is controllable, i.e. moderate. |
