Self-repairing concrete having carbamide resin polymer micro-capsules and method for fabricating same

摘要

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.
