Synopsis
A new retrofit of RC slab with high fluidity and high toughness mortar has been developed in order to relieve the problems in conventional methods of heavy equipments, low compactability and bond effects, difficulty of thin-layer construction and damages on waterproofing membrane due to steel fiber. Characteristics of the materials developed for the above mentioned retrofit is presented in this paper, and the results of the mock-up tests are also reviewed.
Keywords:
