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.
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.
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 environments can have on the planet, while increasing the efficiency and adaptability of the structures.
By adopting sustainable construction, contractors would make the construction plan or sustainable site plan to minimize the environmental impact of the project. According to a study took place in Sri Lanka, [ 20 ] considerations of sustainability may influence the contractor to choose more sustainable, locally sourced products and materials ...
Construction block made from hempcrete Illustration of hemp concrete carbon emissions and sequestration, with a net emissions balance indicating carbon negativity. Hempcrete or hemplime is biocomposite material, a mixture of hemp hurds and lime, [1] sand, or pozzolans, which is used as a material for construction and insulation. [2]
In modern rammed earth buildings, the walls are constructed on top of conventional footings or a reinforced concrete slab base. Contemporary slip formwork in use. The construction of an entire wall begins with a temporary frame, the "formwork", which is usually made of wood or plywood, as a mold for each wall section's desired shape and dimensions.
A small cob building with a living roof Porch of a modern timber framed home. Natural building or ecological building is a discipline within the more comprehensive scope of green building, sustainable architecture as well as sustainable and ecological design that promotes the construction of buildings using sustainable processes and locally available natural materials.
Bamboo construction involves the use of bamboo as a building material for scaffolding, bridges, houses and buildings. Bamboo, like wood , is a natural composite material with a high strength-to-weight ratio useful for structures. [ 1 ]
