Self-Healing Concrete
Introduction Concrete is one of the most widely used construction materials on earth. But concrete has a flaw, its low tensile strength. It needs to be reinforced with the help of steel or iron rods to compensate for its low tensile strength. In turn, concrete protects the steel from corrosion. But when cracks form in concrete, the rods come in contact with the atmosphere, and their corrosion harms the structure's integrity. Here comes the idea of self-healing concrete because if we fill the cracks formed in the concrete, then the next step of corrosion of rods will not occur. This self-healing will not lead to harm to the structure's integrity. First let’s see about concrete’s own self-healing properties Autogenous self-healing concrete Concrete in itself processes naturally specific autogenous healing properties. The healing activity in this method initiates because of the hydration of the clinker's minerals present in it. Here the unhydrated cement particles work as a h...
