Research Projects

Concrete roads and pipelines are prone to cracking, leading to premature unserviceability and failure. To mitigate crack propagation and ensure self-healing, replacements and additives have been suggested. However, the research is still in its research phase. The present researcher aims to study the mechanical and durability behavior of self-healing concrete, as well as its microstructure. The incorporation of self-healing agents allows concrete to heal its cracks autonomously, resulting in sustainable concrete. This could be the next generation material for roads, as they are largely prone to cracking. The methodology includes a literature survey, procurement of materials, experimentation with various specimens, and analysis of results and comparative studies. The expected impact is that using different calcite precipitating bacteria, minerals, and polymers as additives will result in self-healing of cracks in concrete, resulting in sustainable concrete suitable for highly prone to cracking structures like roads and pipelines. The self-healing additives significantly improve the mechanical properties of concrete. An economical approach to self-healing concrete will be proposed for road construction. Technical details of outcomes include the mix proportion of self-healing concrete, mechanical properties, durability properties, and fracture mechanics properties of self-healing concrete.
