Key Lecture - Self-Healing Capacity for a Sustainable High Performance Fiber Reinforced Cementitious Composite
Session
Civil Engineering, Infrastructure and Environment
Description
Challenges that civil engineering industry is facing nowadays have changed compared on what had to be faced in the past decades. Sustainability, economic aspects and life cycle of construction materials represent now important requirements, as highlighted in the new Model Code 2010. New solutions are being developed to provide an answer to the newest code requests. Self-healing/repairing materials can perform an accomplishments of these challenges by introducing an innovative way of thinking for materials, the concept of “bio-mimicking”. Different studies confirmed the self-healing capacity of cementitious composites, depending in the type of activated mechanisms. Microscopic and chemical investigations allowed the observation of different sealing/healing mechanisms, as due e.g. to continuing hydration of un-hydrated cement/binder particles, crystallization of calcium carbonate or the improvement of the bond between fibers and matrix. This paper will try to light up the way through which these mechanisms can promote crack sealing or healing capacity.
