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.
This process can cause the self-healing of fractures in particular conditions. Fagerlund [ 10 ] (2000) determined that, “About 15% of the lime has to be dissolved before strength is affected. This corresponds to about 10% of the cement weight, or almost all of the initially formed Ca(OH) 2 .”
The fracture energy of a living building material compared with two controls: one with no cyanobacteria, and one with no cyanobacteria and a high pH. [2]Self-replicating concrete is produced using a mixture of sand and hydrogel, which are used as a growth medium for synechococcus bacteria to grow on.
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

Ricotta forte (lit. ' strong ricotta ') is a very traditional soft cheese of Basilicata and Apulia, in southeastern Italy.It is creamy, spicy and slightly bitter. [1]Its preparation is similar to the Greek cheese called "kopanisti": [2] the milk is fermented by bacteria and yeast which contribute to the spicy taste and to the very intense aroma.
Ricotta (Italian:) is an Italian whey cheese made from sheep, cow, goat, or Italian water buffalo milk whey left over from the production of other cheeses. Like other whey cheeses, it is made by coagulating the proteins that remain after the casein has been used to make cheese, notably albumin and globulin .
Microbiologically induced calcium carbonate precipitation (MICP) is a bio-geochemical process that induces calcium carbonate precipitation within the soil matrix. [1] Biomineralization in the form of calcium carbonate precipitation can be traced back to the Precambrian period. [ 2 ]
