The Future of Construction: Self-Healing Concrete

Revolution in of the construction materials with the emergence of self- healing concrete may be discussed as the example of transformative invention that may seriously affect the industry.

This cutting-edge material, inspired by the regenerative capabilities of living organisms, offers a groundbreaking solution to one of the most persistent challenges in construction, like crack initiation and the process of material failure.

Self-healing concrete is a kind of concrete with the added realization of self-mitigation by adding special materials in the concrete mixture and this in turn increases the life cycle and sustainability of structures.

The principle of operations of the self-healing concrete is as simple and efficient as it can be. Fibers or microcapsules filled with adhesive liquids like, bacteria, polymers or other chemical agents are incorporated in the concrete mixture. Healing agents are prepositioned in the structure when a crack occurs, and when the crack happens, they break free and do their job as assigned.

When these agents come into contact with air or moisture, they gain the ability to perform a chemical reaction which expands and then seals the crack. It not only prevents crack propagation, but also rebuilds the concrete material, in a certain sense, to repair the concrete itself.

This is a relatively profound implication of this technology. Normal reinforced concrete, as good as it may be in the field of strength, durability, flexibility, etc, is vulnerable to cracking as a result of either environmental change or operational loads. These cracks thus, if not well managed, will lead to more developments on the structure and thus incur a lot of funds for repairs.

It is a fact that when cracks are sealed before it causes considerable damage self-healing concrete helps structures like buildings, bridges, roads and other constructions to have longer life span and usually require less maintenance and repair.

From a sustainability point of view, the advantages of self-healing concrete are just as impressive. The construction industry is one of the most marked industries that have led to the depletion of the environment, and the cutting of trees and the preparation of concrete are known to emit at least 5% of the total CO2 in the world. Thus, self-healing concrete prolongs the lifespan of structures and, therefore, reduces the requirement for new material, hence addressing environmental problems associated with construction and demolition.

Till date, self-healing concrete is more of a concept than a reality but the initial attempts that have been performed show a lot of hope. There are a wealth of case studies and pilot schemes that have shown that this will radically transform construction practices.

When research is advanced further, the extent of the incorporation of this advanced material for developments is set to increase, making the future built environment more resistant and sustainable. Therefore, this concept represents an effective and ecological approach to address some of the problems of maintenance and durability of infrastructures.

With the advancement toward a revolutionary world where there is a thrust for lowered environmental impacts, self-healing concrete can be seen as a virtue sign, which will mark a revolution in the construction industry for years to come.
