Papercrete
Papercrete is a building material that consists of re-pulped paper fiber with Portland cement or clay and/or other soil added. First patented in 1928, it was revived during the 1980s. Although perceived as an environmentally friendly material due to the significant recycled content, this is offset by the presence of cement. The material lacks standardisation, and proper use therefore requires care and experience. Eric Patterson and Mike McCain, who have been credited with independently "inventing" papercrete (they called it "padobe" and "fibrous cement"), have both contributed considerably to research into machinery to make it and ways of using it for building. Manufacture The paper to be used can come from a variety of sources, including newspaper, junk mail, magazines, books. A mixer is used to pulp the mix. Depending on the type of mixer, the paper may be soaked in water beforehand. Standardization and commercial acceptance As of 2007, papercrete lacks approval from the Inte ...

Fiber Cement
Fibre cement is a composite building and construction material, used mainly in roofing and facade products because of its strength and durability. One common use is in fiber cement siding on buildings. Material description The term "cement" originates from the Latin word "''Caementum''", which signifies chopped stone. Cement describes a substance which will react chemically with water and develop into a material as hard as stone. In fibre cement there is a fibre reinforcement, which contributes to making the fibre-cement material even stronger. Together with a carefully planned production process, fibre cement makes it possible to develop strong and long lasting construction materials. Today fibre cement is considered as a material physically suited for construction products such as cladding and roofing. It is primarily due to its function, performance and commercial value. Fibre cement flat sheet classified, by accredited laboratories, as Category A according to BS EN 12467:20 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pykrete
Pykrete is a frozen ice composite, originally made of approximately 14% sawdust or some other form of wood pulp (such as paper) and 86% ice by weight (6 to 1 by weight). During World War II, Geoffrey Pyke proposed it as a candidate material for a supersized aircraft carrier for the British Royal Navy. Pykrete features unusual properties, including a relatively slow melting rate due to its low thermal conductivity, as well as a vastly improved strength and toughness compared to ordinary ice. These physical properties can make the material comparable to concrete, as long as the material is kept frozen. Pykrete is slightly more difficult to form than concrete, as it expands during the freezing process. However, it can be repaired and maintained using seawater as a raw material. The mixture can be moulded into any shape and frozen, and it will be tough and durable, as long as it is kept at or below freezing temperature. Resistance to gradual creep or sagging is improved by lowering ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Fibro
Asbestos cement, genericized as fibro, fibrolite (short for "fibrous (or fibre) cement sheet") or AC sheet, is a building material in which asbestos fibres are used to reinforce thin rigid cement sheets. Although invented at the end of the 19th century, the material was adopted extensively during World War II to make easily-built, sturdy and inexpensive structures for military purposes, and it continued to be used widely following the war as an affordable external cladding for buildings. Advertised as a fireproof alternative to other roofing materials such as asphalt, asbestos-cement roofs were popular, not only for safety but also for affordability. Due to asbestos-cement's imitation of more expensive materials such as wood siding and shingles, brick, slate, and stone, the product was marketed as an affordable renovation material. Asbestos-cement faced competition with the aluminum alloy, available in large quantities after WWII, and the reemergence of wood clapboard and viny ...

California State Polytechnic University, Pomona
California State Polytechnic University, Pomona (Cal Poly Pomona, CPP, or Cal Poly"Cal Poly" may also refer to California Polytechnic State University, San Luis Obispo in San Luis Obispo. See the '' name'' section of this article for more information.) is a public polytechnic university in Pomona, California. It is one of three polytechnic universities in the California State University system. Cal Poly Pomona began as the southern campus of the California Polytechnic School (today known as Cal Poly San Luis Obispo) in 1938 when the Voorhis School for Boys and its adjacent farm in the city of San Dimas were donated by Charles Voorhis and his son Jerry Voorhis. Cal Poly's southern campus grew further in 1949 when it acquired the University of California, W.K. Kellogg Institute of Animal Husbandry from the University of California. UC's W.K. Kellogg Institute of Animal Husbandry was located in the neighboring city of Pomona, California and had previously belonged to Will Keit ...

Sustainable
Specific definitions of sustainability are difficult to agree on and have varied in the literature and over time. The concept of sustainability can be used to guide decisions at the global, national, and individual levels (e.g. sustainable living). Sustainability is commonly described as having three dimensions (also called pillars): environmental, economic, and social. Many publications state that the environmental dimension (also called "planetary integrity" or "ecological integrity") is the most important, and, in everyday usage, "sustainability" is often focused on countering major environmental problems, such as climate change, Biodiversity loss, loss of biodiversity, loss of ecosystem services, land degradation, and Air pollution, air and water pollution. Humanity is now exceeding several "planetary boundaries". A closely related concept is that of sustainable development, and the terms are often used synonymously. However, UNESCO distinguishes the two thus: "''Sustainabili ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Rebar
Rebar (short for reinforcing bar), known when massed as reinforcing steel or reinforcement steel, is a steel bar used as a Tension (physics), tension device in reinforced concrete and reinforced masonry structures to strengthen and aid the concrete under tension. Concrete is strong under Compression (physics), compression, but has weak tensile strength. Rebar significantly increases the tensile strength of the structure. Rebar's surface features a continuous series of ribs, lugs or indentations to promote a better bond with the concrete and reduce the risk of slippage. The most common type of rebar is carbon steel, typically consisting of hot-rolled round bars with deformation patterns embossed into its surface. Steel and concrete have similar coefficient of thermal expansion, coefficients of thermal expansion, so a concrete structural member reinforced with steel will experience minimal differential stress (mechanics), stress as the temperature changes.

Tensile Strength
Ultimate tensile strength (UTS), often shortened to tensile strength (TS), ultimate strength, or F_\text within equations, is the maximum stress that a material can withstand while being stretched or pulled before breaking. In brittle materials the ultimate tensile strength is close to the yield point, whereas in ductile materials the ultimate tensile strength can be higher. The ultimate tensile strength is usually found by performing a tensile test and recording the engineering stress versus strain. The highest point of the stress–strain curve is the ultimate tensile strength and has units of stress. The equivalent point for the case of compression, instead of tension, is called the compressive strength. Tensile strengths are rarely of any consequence in the design of ductile members, but they are important with brittle members. They are tabulated for common materials such as alloys, composite materials, ceramics, plastics, and wood. Definition The ultimate tensile streng ...
