TL;DR: In this paper, a review of the existing studies on recycling municipal and construction solid waste for the manufacture of geopolymer composites is presented, and the results indicate that although the inclusion of such waste might depress some of the attributes of these composites, proper proportion design and suitable treatment technique could alleviate these detrimental effects and further smooth the recycling progress.

TL;DR: In this paper, a review has been conducted on various healing agents, encapsulation techniques, as well as experimental approaches, basing on existing substantial studies, there is no consistent agreement on the effective criteria for evaluating encapsulation-based self-healing and mature solution for increasing the survival ratio of capsules during mixing.

TL;DR: In this paper, the effect of chloride environment containing various concentrations of chloride ion (Cl−) on self-healing performance of pre-cracked cementitious composite containing crystalline admixture (CA) and MgO expansive agent (MEA) was investigated under wet-dry cycles in chloride solutions.

TL;DR: In this paper, the authors focused on the effects of crack healing on crack closure and mechanical performance recovery of crack-healed cementitious composite, including flexural compressive behaviours, and found that the bonding interface dominated the flexural strength recovery, and therefore autonomous self-healing yielded the maximum selfhealing efficiency.

TL;DR: Based on the extended finite element method (XFEM) and cohesive surface technique, the interface cracks between healing agent and cementitious materials in the self-healing mortar beam under three-point bending are numerically investigated in this article.
