Abstract
A self-repairing concrete includes carbamide resin polymer micro-capsules, in which the carbamide resin polymer micro-capsules are mixed for a fixed function of micro-cracks. The quality mixture ratio is: concrete/micro capsules/water=100:1-15:15-50. The manufacturing method is weighing a full amount of water in a container, adding carbamide resin polymer micro-capsules, stirring, until fully dispersed microcapsules; pouring the water into the mixing container, adding the corresponding quality of cement; stirring; adding sand and gravel filling materials, conducting worksite watering, ⅓ volume for each time, vibrating, and air exhausting; until the slurry filling mold.

A self-repairing concrete comprising:
- carbamide resin polymer micro-capsules, wherein a quality mixture ratio of the self-repairing concrete is:
- concrete/micro capsules/water=100:1-15:15-50.
A method for fabricating a self-repairing concrete comprising:
- (1) Weighing enough dose of water, adding in a proper portion of carbamide resin polymer micro-capsules, then stirring until fully dispersed;
- (2) Poring the above mixture to a mixing container, adding in a corresponding dose of concrete;
- (3) Slower stirring the concrete and then faster stirring;
- (4) Gradually adding concrete slurry, each time at ⅓ of total dose, vibrating and excluding bubbles until the third times of concrete slurry being added to fill in the mixing container.
A method for fabricating a self-repairing concrete comprising:

- (2) Poring the above mixture to a mixing container, adding in corresponding dose of concrete;
- (3) Slower stirring the concrete, and then faster stirring;
- (4) Gradually or step by step irrigating work pieces after vibrating the concrete mixture;
- (5) Putting the above mixture aside for 1-2 hours, scraping the concrete slurry overflowed from the mold, then laying aside for 21-26 hours;
- (6) Removing the mold and then transferring the sample to conservation container for 25-31 days.
