TL;DR: In this article, the results of a series of self-healing experiments conducted on reinforced mortar beams containing adhesive-filled glass reservoirs were presented, showing that both primary and secondary healing occurs during the first and second loading cycles respectively.

TL;DR: This state of the art provides a comprehensive and critical review of the experimental methods and techniques, which have been employed to characterize and quantify the self-sealing and/or self-healing capacity of cement-based materials, as well as the effectiveness of the different self- Sealing and or self- healing engineering techniques, together with the methods for the analysis of the chemical composition and intrinsic nature of the self,healing products.

TL;DR: In this paper, a wide range of concretes was evaluated to determine the influences of constituents on the stress distributions at the matrix-aggregate interface, around the aggregate and in the matrix close to the aggregate.

TL;DR: In this article, a crack-closure system for cementitious materials using shrinkable polymer tendons is presented, which is achieved by thermally activating the shrinkage mechanism of the restrainable tendons after the material has undergone initial curing.

TL;DR: In this article, a thermodynamically consistent plastic directional-damage-contact model for concrete is proposed, which uses planes of degradation that can undergo damage and separation but which can regain contact according to a contact state function.
