A comparison of potential healing agents for vascular-based self-healing concrete

Vascular self-healing concrete is an innovative technology that can potentially improve the durability and longevity of structures. However, limited research available concerning this type compared to intrinsic or capsule-based healing. As rheology curing properties a healing agent dictate optimal design configuration vascular network, series testing procedures for evaluating agents further explored. In study, suitability various commercially considered using network system in mechanical loading water absorption test set-ups. particular configuration, high sealing efficiencies were obtained most used, polyurethanes epoxy resin studied showed load regain values. This work provides methodology select terms its regain, efficiency, rheology, properties, be used determine suitable applications.
