| description | The invention discloses preparation of cement material self-repairing microspheres and application of the self-repairing microspheres in cement concrete. The microsphere preparation comprises the following steps: selecting repairing liquid with good repairing performance for cement and concrete; designing and screening self-repairing microsphere functional monomers; selecting cross-linking agent and porogen, and polymerizing the obtained functional monomers and the repairing liquid into microspheres with self-repairing function under proper conditions by using a molecular self-assembly technology; preparing self-repairing microspheres from the repairing liquid, the monomers, initiator, cross-linking agent, porogen and emulsifier under certain conditions in a certain proportion; and mixing the prepared cement material self-repairing microspheres in the cement and cement concrete to repair the material. By mixing the self-repairing microspheres, the breaking strength and compression strength of the cement concr |
