Research Abstract

Some types of self-healing FRCCs (fiber reinforced cementitious composite) were studied and developed. It was confirmed that FRCCs using proper raw materials, e.g. synthetic fibers and/or other admixtures, had great capability of the self-healing function via microscopic observation and other performance tests. Such self-healing process was also confirmed under various curing conditions. Application of self-healing FRCCs was suggested for example 'maintenance free waterproof layer' of buildings.
