Wang, J.Y. (author), Van Vlierberghe, S. (author), Dubruel, P. (author), Verstraete, W. (author), De Belie, N. (author)Self-healing concrete is regarded as a promising solution to reduce the high maintenance and repair cost of concrete infrastructure. Due to the limited autogenous healing capacity of concrete as such, additives are needed to enhance its self-healing properties. Among various strategies, microbial-based self-healing has gained increasing...conference paper 2013

Chen, Z. (author), Xu, Z. (author), Wang, G. (author), Li, H. (author), Chen, B. (author), Zeng, X.C. (author), Tan, L. (author)Crystalline solids are solid materials whose constituent atoms, molecules, or ions are arranged in a highly regulated fashion. Due to lack of rotational freedom in their stacking, they have been known as fragile materials. Even though some efforts have been dedicated to bind or mend defects/cracks in amorphous materials like concrete or polymers...conference paper 2013

Van Tittelboom, K. (author), Snoeck, D. (author), Wang, J. (author), De Belie, N. (author)While the Japanese researchers Ohama et al. [1] already mentioned in 1992 that a self-healing effect was noticed when polymer-modified concrete without hardener was made, the real pioneer in the research on self-healing concrete is Carolyn Dry from Illinois. The first time she proposed the use of encapsulated polymers to obtain self-healing...conference paper 2013

Rong, M.Z. (author), Zhang, M.Q. (author), Yuan, C.E. (author), Wang, F. (author)Generally, intrinsic self-healing polymers based on reversible covalent bonds scission and reconnection would lose their load bearing capability as a result of molecular cleavage during healing process. This shortcoming also results in creep deformation of the products. To solve the problem, we introduce a novel healing mechanism by using...conference paper 2013
