Emerging Technologies in Cementitious Material Design: Autonomous Healing and Durability Enhancement Mechanisms
-
Parveen Kumar
Abstract
Cementitious materials provide the basis of most modern construction but are plagued with problems associated with durability, cracking and maintenance which could ultimately hinder the long-term performance and sustainability of construction structures. These problems can rarely be solved with conventional repair methods, and that is why new strategies for increasing the durability of these materials are required. The current innovational trends in various self-healingself-healing techniques including bacterial induced calcite precipitation, encapsulated healing agents as well as crystalline admixtures are evident solutions to the above challenges. These techniques are used to provide structure repair, seepage control, and extend the durability of cementitious structures up to several generations from the time of treatment without seeing or needing repairs again.
This review systematically discusses the most recent developments of self-healingself-healing systems with particular emphasis on their working principles, efficiency, and real-world usability. Self-healing strategies examined include bacterial autonomic systems that utilize microbial behaviour to fill the crack, encapsulation methods for using the crack to release the agent, and the use of nanotechnology for improvement in self-healing efficacy. This enables comparative analysis of these technologies side by favouring their duration enhancement capability environmental sustainability and scalability for industrial application aspects among others.
The results prove the generation shift of cementitious materials leading to self-healingself-healing and sustainable structures. However, practical difficulties including the stability of the healing agents and the cost-effectiveness of large-scale installation are complex issues of concern. It is therefore important to approach such issues through a multi-disciplinary research and development efforts in order to scale up the use of autonomous healing technologies in the construction industry. Potential future enhancements include the real-time monitoring of artificial intelligence and the Internet 34of Things and designing additional-agent structures using a combination of those powerful healing techniques in order to acquire better results.
