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.
Cast Earth is a proprietary natural building material developed since the mid-1990s by Harris Lowenhaupt and Michael Frerking [1] based on the earlier Turkish Alker, which is a concrete-like composite with soil of a suitable composition as its bulk component stabilized with about 15% calcined gypsum (plaster of Paris) instead of Portland cement.
Hempcrete is easier to work with than traditional lime mixes and acts as an insulator and moisture regulator. It lacks the brittleness of concrete and consequently does not need expansion joints. [3] Typically, hempcrete has good thermal and acoustic insulation capabilities, but low mechanical performance, specifically compressive strength. [4]

Alternative natural materials are natural materials like rock or adobe that are not as commonly used as materials such as wood or iron. Alternative natural materials have many practical uses in areas such as sustainable architecture and engineering. The main purpose of using such materials is to minimize the negative effects that built ...
In a later work, Du Plessis furthers the definition for sustainable construction to touch on the importance of sustainability in social and economic contexts as well. [33] This is especially relevant in construction projects in the Global South, where local value systems and social interactions may differ from the western context in which ...
The environmental impact of concrete, its manufacture, and its applications, are complex, driven in part by direct impacts of construction and infrastructure, as well as by CO 2 emissions; between 4-8% of total global CO 2 emissions come from concrete. [1]
The ruins of a Han dynasty (202 BCE – 220 CE) Chinese watchtower made of rammed earth in Dunhuang, Province of Gansu, China, at the eastern end of the Silk Road.. Rammed earth is a technique for constructing foundations, floors, and walls using compacted natural raw materials such as earth, chalk, lime, or gravel. [1]
