On the other hand, concrete may be altered to provide self-healing capabilities for cracks. There are many solutions for improving autogenous healing by adding the admixtures, such as mineral additions, crystalline admixtures, and superabsorbent polymers. [6] Further, concrete can be modified to built-in autonomous self-healing techniques.
Calcium is a binding agent in Roman concrete, which makes it remarkably strong. Figuring out where it came from was the key to solving this architectural mystery.
Intrinsic self-healing materials do not have a sequestered healing agent but instead have a latent self-healing functionality that is triggered by damage or by an outside stimulus. [57] Extrinsic self-healing materials can achieve healing efficiencies over 100% even when the damage is large. [58]
Concrete is a composite material composed of aggregate bonded together with a fluid cement that cures to a solid over time. Concrete is the second-most-used substance in the world after water, [1] and is the most widely used building material. [2] Its usage worldwide, ton for ton, is twice that of steel, wood, plastics, and aluminium combined. [3]

Self-healing concrete is a type of innovative concrete designed to repair cracks autonomously that form over time. The self-healing concrete market is rapidly growing due to several reasons. The advanced material incorporates healing agents, such as bacteria, capsules, or other chemical compounds, which activate upon crack formation.
These lime clasts have a brittle structure that was most likely created in a "hot-mixing" technique with quicklime rather than traditional slaked lime, causing cracks to preferentially move through the lime clasts, thus potentially playing a critical role in the self-healing mechanism. [1] Concrete and, in particular, the hydraulic mortar ...
A living building material (LBM) is a material used in construction or industrial design that behaves in a way resembling a living organism.Examples include: self-mending biocement, [1] self-replicating concrete replacement, [2] and mycelium-based composites for construction and packaging.
