Rammed earth is a technique for constructing foundations, floors, and walls using compacted natural raw materials such as earth, chalk, lime, or gravel. [1] It is an ancient method that has been revived recently as a sustainable building method. Under its French name of pisé it is also a material for sculptures, usually small and made in molds.
Reduced embedded carbon. Post-tensioned stone causes the emission of <1/3rd of carbon dioxide greenhouse gas relative to concrete. [1] [15] Lower cost. A study of a 30-storey office block found that using PT stone floor panels was cheaper than concrete floors. [9]
Slab track with flexible noise-reducing rail fixings, built by German company Max Bögl, on the Nürnberg–Ingolstadt high-speed line. A ballastless track or slab track is a type of railway track infrastructure in which the traditional elastic combination of sleepers and ballast is replaced by a rigid construction of concrete or asphalt.
Fallingwater's asymmetrical floor plan was loosely derived from the cruciform plan of the Prairie houses. [98] It has a floor area of 5,330 square feet (495 m 2), [16] [91] of which 2,445 square feet (227.1 m 2) is composed of outdoor terraces. [77] [91] [297] The remaining 2,885 square feet (268.0 m 2) is indoors.
Due to its poor tensile strength, stone cannot be used for long spans, so (unlike reinforced concrete), architects and builders must switch modes during design and construction of horizontal and vertical components. MP stone can be used in conjunction with concrete floors, manufactured timber panels, and post-tensioned stone flooring units. [16]
Small-scale rooftop wind turbines have been known to be able to generate power from 10% to up to 25% of the electricity required of a regular domestic household dwelling. [17] Turbines for residential scale use are usually between 7 feet (2 m) to 25 feet (8 m) in diameter and produce electricity at a rate of 900 watts to 10,000 watts at their ...
One reason why the carbon emissions are so high is because cement has to be heated to very high temperatures in order for clinker to form. A major culprit of this is alite (Ca 3 SiO 5), a mineral in concrete that cures within hours of pouring and is therefore responsible for much of its initial strength. However, alite also has to be heated to ...
Shallow foundations of a house versus the deep foundations of a skyscraper. Foundation with pipe fixtures coming through the sleeves. In engineering, a foundation is the element of a structure which connects it to the ground or more rarely, water (as with floating structures), transferring loads from the structure to the ground.
