Microbial calcium carbonate has been widely investigated to self-heal concrete cracks.
However, the issue revolving around the efficacy of crack self-healing remains important. In …

It is a well known fact that concrete structures are very susceptible to cracking which allows
chemicals and water to enter and degrade the concrete, reducing the performance of the …

Calcium carbonate precipitation, caused by the metabolic activity of bacteria, is a good idea
to improve concrete performance. This study was aimed at investigating the effect on using …

Crack occurrence in reinforced concrete should be minimized for both durability and
economical reasons as crack repair is costly. Autogenous repair, or self-healing, of concrete …

Micro-cracks are the main cause to structural failure. One way to circumvent costly manual
maintenance and repair is to incorporate an autonomous self-healing mechanism in …

Self-healing concrete is regarded as a promising solution to reduce the high maintenance
and repair cost of concrete infrastructure. Due to the limited autogenous healing capacity of …

With time, the development of micro-cracks in concrete is a frequently reported problem in
the structures due to the ingress of harmful substances, leading to the degradation of its …

Microbial induced carbonate precipitation (MICP) has become one of the most attractive
strategies to achieve self-healing of concrete cracks in recent decades. In order to provide a …

Evidence of microbial involvement in carbonate precipitation has led to the exploration of
this process in the field of construction materials. One of the first patented applications …

The self-healing (SH) of cracks in concrete using bacteria without the need for manual
involvement is a viable answer to the problem of long-term concrete sustainability. When …
