In the concrete industry, legal disputes might occur when a built structure performs worse than it was supposed to during design phase. When dealing with underperformance of self-healing (e.g., no regain water tightness after cracking), these likely be related questioning if healing agents were actually included in material or not. this study, methodology based on Gas chromatography is proposed...

In the current study, experiments were carried out to investigate structural performance of reinforced concrete (RC) beams with a self-healing cover zone. The zone consists 1.5-cm-thick layer bacteria-embedded strain hardening cementitious composite (SHCC) for combination crack width control and healing. aim is bring together two emerging technologies (i.e., strain-hardening) that show great po...

Extreme environments are aggressive for concrete structures, hence a performance-based design is crucial to guarantee the durability during service life. Nonetheless, there knowledge gap regarding influence of cracks on standard and self-healing concrete. This research focuses monitoring cracked with two commercial healing agents: bacteria-based agent (BAS) crystalline admixture (CA). After cra...
