A Review of Self-healing Concrete Research Development

Self-healing concretes are being widely recognized as a remedial technique to improve the durability of concrete. Although, few review papers on self-healing concrete were published, a strong review on all aspects of self-healing concrete cannot be found. In this paper, natural, chemical and biological processes of self-healing concrete technologies were completely reviewed. The main focus of the study is for the biological processes. The review presents a new insight into the research for the treatment of unexpected cracking of concrete. The information presented in this paper can be considered significant for biotechnologists and bioprocess engineers to have comprehensive updates on the current status-quo of selfhealing concrete.
