(Concrete Engineering) The addition of water to the cement mix whether at the batch plant, during transit or at the jobsite to achieve the specified water to cement ratio.
(english) A eutectoid transformation product of ferrite and a fine dispersion of carbide, generally formed at temperatures below 840 to 930 F (450 to 500 C): upper bainite is an aggregate containing parallel lath-shape units of ferrite, produces the so-called feathery appearance in optical microscopy, and is formed at temperatures above about 660 F (350 C); lower bainite consists of individual plate-shape units and is formed at temperatures below about 660 F (350 C). Also, a slender, needle-like (acicular) microstructure appearing in spring steel strip characterized by toughness and greater ductility than tempered Martensite. Bainite is a decomposition product of Austenite best developed at interrupted holding temperatures below those forming fine pearlite and above those giving Martensite.
(Environmental Engineering) The depth at which an inflection point occurs in a lake temperature profile.
(Environmental Engineering) An organic compound with a carbonyl at one end of a hydrocarbon group.
(english) A three-roll cluster used to control line tension at strategic locations on the line.
(english) In hypereutectoid steel, the temperature at which cementite goes into complete solution with austenite.
(english) Machine located at each delivery reel to automatically place circumference bands around completed coils.
(english) Work done primarily at a bench with hand tools. Occasionlly suplemented by small power-driven tools.
(Software Engineering) a point at which manager or the customer decides whether the project should proceed
(english) In hypoeutectoid steel, the temperature at which transformation of ferrite into austenite is completed upon heating.
(english) Upper limit of normal stress of a beam at which fracture or excessive plastic deformation occurs.
(english) The intensity of deformation at a point in an object. See normal strain and shear strain.
