A SELF REPAIRING CONCRETE CONTAINING MICROCAPSULES OF UREA FORMALDEHYDE RESIN AND PRODUCING METHOD THEREOF

摘要

A self-repairing concrete includes urea-formaldehyde resin polymer micro-capsules, in which the urea-formaldehyde 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 urea-formaldehyde 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, 1/3 volume for each time, vibrating, and air exhausting; until the paste filling mold.
