(english) Steel melted in a furnace with an acid bottom and lining and under a slag containing an excess of an acid substance such as silica.
(Concrete Engineering) Microscopic air bubbles intentionally incorporated in mortar or concrete, to improve workability and durability (usually imparting a higher degree of resistance to freezing and thawing).
(Software Engineering) a named element of the problem domain containing data and processing
(Software Engineering) testing only a selected set of program paths and data inputs
(Software Engineering) a comprehensive diagrammatic notation for the analysis and design of software
(english) A small core-blowing machine, utilizing a removable sand magazine and blow heat.
(english) Steels in which the deoxidisation is controlled to produce an intermediate structure between a rimmed and killed steel, Sometimes referred to as semi-killed steels, they possess uniform properties throughout the ingot and amongst their applications are boiler plate and structural sections.
(english) Copper base alloys in which zinc is the principal alloying element. Brass is harder and mechanically stronger than either of its alloying elements copper or zinc. It is formable and ductile; develops high tensile strength with cold-working and is not heat treatable.
(english) Steel melted in a furnace with a basic bottom and lining and under a slag containing an excess of a basic substance such as magnesia or lime.
(english) Hardened, tempered, polished and blued or yellow flat steel with dressed edges. Carbon content about 1.00. Material has to possess good flatness, uniform hardness and high elasticity.
(Concrete Engineering) Method of maintaining sufficient internal humidity and proper temperature for freshly placed concrete to assure proper hydration of the cement, and proper hardening of the concrete.
(english) The addition of boron in the range 0.0005-0.005% to certain steels increases the hardenability. A range of boron steels is now listed in the current BS 970 and are widely used for the production of cold headed fastenings.
