A kind of prestress hole path pressure grouting agent with self-repair function

The invention discloses a kind of prestress hole path pressure grouting agent with self-repair function, this grouting agent is made up of the raw material of following weight percent: high efficiency water reducing agent 5 ~ 20%, adjustable solidification agent 0.2 ~ 1.0%, thixotropic agent 0.01 ~ 0.2%, plastic expansion component 5 ~ 20%, middle and later periods expansion component 40 ~ 70%, silicon ash 5 ~ 10%, calcium ion compensator 4 ~ 6%, inorganic salt crystalline deposit agent 5 ~ 20%, active catalyst 5 ~ 20%, redispersible latex powder 0.05 ~ 0.3%.Grouting agent prepared by the present invention is compounded with the function ingredients such as dispersion agent, adjustable solidification agent, thixotropic agent, penetrant crystalline composition material and cohesion modifiers on the basis of microdilatancy function, polyfunctional compound achieves the improved-type regulation and control to press mortar rheological property, improve the mechanical property of slurry volume stability and hardened paste, further enhancing the self-reparing capability of press mortar and achieve its permanent self-repair function.
