A novel taxanomy on self-healing concrete research development

Abstract

Self-healing concrete has beenwidely recognized as remedial technique to improve the durability of concrete.Some review papers have been published on self-healing concrete. Yet thehierarchical structure foritsclassificationneeds to be reviewed. This study presents a novel taxonomy making use of advances inknowledgefor self-healing concrete. The study addresses the general taxonomy of self-healing concrete to beclassified into three categories i.e., natural, chemical and biological processes. The focus is on the study ofthe biological processes.The review and taxonomy presents a new insight into the research on treatment ofunexpected cracking of concrete. The information presented in this paper is significant for biotechnologistsand bioprocess engineers to have comprehensive updates on the current status-quo ofself-healing concrete.
