Self-healing concrete through microencapsulated calcium nitrate is a novel approach to enhance durability and decrease the costs associated with maintenance and repairs. However, to fully assess the potential of this technology, there are many questions to be answered, ranging from identifying the microcapsule properties that are successfully carry the healing agent, to the effect of the microcapsule size, concentration (by weight of cement), and morphology have on the intrinsic concrete material properties and self-healing potential. Hence, the objectives of this study were to: (a) Develop a microencapsulation procedure for calcium nitrate as the healing agent; (b) Measure the short-term healing …

Durability of reinforced concrete structures depends highly on the integrity of the concrete which protects the structure from the environment. However, concrete is a brittle material and as such it is prone to cracking which allows for detrimental agents to penetrate the structure and produce early deterioration. Embedding microcapsules with chemical healing agents in concrete materials for self-healing applications as well as implementing SMAs as reinforcement of concrete structures for self-closing of cracks are both state-of-the-art techniques with enormous potential for enhancement of concrete infrastructure durability. In this work, both techniques are combined as an alternative for superior self-healing of …
