Mo-Sai
Mo-Sai is a method of producing precast concrete Cladding (construction), cladding panels. It was patented by John Joseph Earley in 1940. The Mo-Sai institute later refined Earley's method and became the leader in exposed aggregate concrete. The Mo-Sai Institute, an organization of precast concrete manufacturers, adhered to the Mo-Sai method of producing the exposed aggregate precast concrete panels. A pivotal development in this technique occurred in 1938, when the administration buildings at the David Taylor Model Basin were built with panels used as permanent forms for cast-in-place walls. This was the first use of the Mo-Sai manufacturing technique produced in collaboration with the Dextrone Company of New Haven, Connecticut. Working from this background, the Dextone Company refined and obtained patents and copyrights in 1940 for the methods under which the Mo-Sai Associates, later known as Mo-Sai Institute Inc. The Mo-Sai Institute grew to include a number of licensed manufactu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Precast Concrete
Precast concrete is a construction product produced by casting concrete in a reusable molding (process), mold or "form" which is then cured in a controlled environment, transported to the construction site and maneuvered into place; examples include precast beam (structure), beams, and wall panels for tilt up construction. In contrast, cast-in-place concrete is poured into site-specific forms and cured on site. Recently lightweight expanded polystyrene foam is being used as the cores of precast wall panels, saving weight and increasing thermal insulation. Precast stone is distinguished from precast concrete by the finer construction aggregate, aggregate used in the mixture, so the result approaches the natural product. Overview Precast concrete is employed in both interior and exterior applications, from highway, bridge, and hi-rise projects to tilt-up building construction. By producing precast concrete in a controlled environment (typically referred to as a precast plant), ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cladding (construction)
Cladding is the application of one material over another to provide a skin or layer. In construction, cladding is used to provide a degree of thermal insulation and weather resistance, and to improve the appearance of buildings. Cladding can be made of any of a wide range of materials including wood, metal, brick, vinyl, and composite materials that can include aluminium, wood, blends of cement and recycled polystyrene, wheat/rice straw fibres. Rainscreen cladding is a form of weather cladding designed to protect against the elements, but also offers thermal insulation. The cladding does not itself need to be waterproof, merely a control element: it may serve only to direct water or wind safely away in order to control run-off and prevent its infiltration into the building structure. Cladding may also be a control element for noise, either entering or escaping. Cladding can become a fire risk by design or material. Description Cladding in construction is material applied over ...

Dextrone Company
Diquat is the ISO common name for an organic dication that, as a salt with counterions such as bromide or chloride is used as a contact herbicide that produces desiccation and defoliation. Diquat is no longer approved for use in the European Union, although its registration in many other countries including the USA is still valid. Synthesis Pyridine is oxidatively coupled to form 2,2′-bipyridine over a heated Raney nickel catalyst. The ethylene bridge is formed by the reaction with 1,2-dibromoethane : History Diquat's herbicidal properties were recognized in 1955 in the Imperial Chemical Industries (ICI) laboratories at Jealott's Hill, following its first synthesis at ICI's Dyestuffs Division in Blackley, England. It was active on test plants at application rates as low as 0.1 lb/acre. It was found that only those quaternary salts which were capable of being converted by reducing agents to radical cations had herbicidal activity and another of these was paraquat, which ...

David Taylor Model Basin
The David Taylor Model Basin (DTMB) is one of the largest ship model basins—test facilities for the development of ship design—in the world. DTMB is a field activity of the Carderock Division of the Naval Surface Warfare Center. History In 1896, David Watson Taylor designed and supervised construction of the Washington Navy Yard's Experimental Model Basin which was at that time the best facility in the world. That facility was a significant design testing capability before, during, and after World War I. Inadequacies in that facility led the navy to look for a new model capability. The new navy modeling facility – named for David Taylor – was built in 1939 in today's community of Carderock just west of Bethesda, Maryland in Montgomery County. The Carderock facility contains multiple test basins (towing tanks for models) designed for a variety of testing capabilities. DTMB has strongly influenced naval architecture for 70 years.
