Self-healing concrete has emerged as one of the prospective materials to be used in future constructions, substituting conventional with view extending service life structures. As a proof concept, over last several years, many studies have been executed on effectiveness addition self-healing agents crack sealing and healing mortar, while level are still rather limited. In most cases, mix design...

Self-healing is an ideal mechanism for concrete to achieve self-repair of microcracks . While extensive efforts have been invested in capsule-based autonomous self-healing, the dilemma between capsules’ survivability during mixing and their rapture upon cracking release healing agents remains unsolved. This study aims address this challenge by investigating a lignin-based capsule system with tu...

Self-healing concrete has shown excellent potential in improving the durability of (reinforced) structures and reducing need for their repair maintenance. This been further substantiated by several successful full-scale demonstrator projects. Nevertheless, industrial uptake technology is lagging behind, mainly due to higher initial cost compared traditional concrete. In addition, it well known ...

As an alternative to the usage of axenic bacteria achieve microbially induced calcium carbonate precipitation (MICP), this study evaluates two non-axenic biomasses as self-healing agents. A fungi-based consortium (Yeast) and heterotrophic nitrifiers (HTN) were harvested from incubation agricultural side streams. The characteristics identified through flow cytometry, total suspended solids volat...
