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.
The ancient Romans used a type of lime mortar that has been found to be self-healing. [8] The stratlingite crystals form along the interfacial zones of Roman concrete, binding the aggregate and mortar together and this process continued even after 2000 years and it was discovered by the geologist Marie Jackson and her colleagues in 2014.
In contrast, self-healing materials counter degradation through the initiation of a repair mechanism that responds to the micro-damage. [1]: 1–2 Some self-healing materials are classed as smart structures, and can adapt to various environmental conditions according to their sensing and actuation properties. [1]: 145

During the 1980s, Okamura and his Ph.D. student Kazamasa Ozawa at the University of Tokyo developed self-compacting concrete (SCC) which was cohesive, but flowable and took the shape of the formwork without use of any mechanical compaction. SCC is known as self-consolidating concrete in the United States. SCC is characterized by the following:
