Development of the outer wall repair method of concrete buildings using three-dimensional fiber material.

Part 4: Verification of long-term durability of the developed repair method

Abstract

The authors developed an outer wall repair technology of concrete buildings using the three-dimensional fiber material before.We have examined the long term validity of the new technique using an outer wall specimen repaired with the technique and placed in outdoors for 14 years.We have successfully confirmed the validity from the evaluation test.Regarding the proof stress of the net holding tiles of outer walls, it was recognized that no deteriorating change occurred by aging.
