Suggested Key Words: Cementitious Composites, Cement, Self Healing
Abstract: Cementitious composites engineered for self-healing, combining selfcontrolled
tight crack width and extreme tensile ductility. Self-healing takes place
automatically at cracked locations without external intervention. In the exemplary
embodiment, fiber-reinforced cementitious composites with self-controlled tight
crack width less than 50µm and tensile ductility more than 2% are prepared.
Self-healing in terms of mechanical and transport properties recovery of predamaged
(by pre-cracking) composite is revealed in a variety of environmental
exposures, include wetting and drying cycles, water permeation, and chloride
submersion.
