Rebound

(Concrete Engineering) Wet shotcrete or sand and cement which bounces away from a surface again at which pneumatically applied mortar is being projected.

Precast

(Concrete Engineering) A concrete unit, structure or member that is cast and cured in an area other than its final position or place.

Abrasive Wear

(english) The displacement and / or detachment of metallic particles from a surface as a consequence of being exposed to flowing fluids or gases.

Abrasive 2

(english) Natural – sandstone,emery,corundum,diamonds, or Artificial – silicon carbide,aluminum oxide – material used for making grinding wheels,andpaper,abrasive and lapping compunds.

Statically indeterminate:

(english) A statically indeterminate structure is one where there is more than one distribution of internal forces and/or reactions which satisfies equilibrium.

Oxidative phosphorylation

(Environmental Engineering) The synthesis of the energy storage compound adenosine triphosphate (ATP) from adenosine diphosphate (ADP) using a chemical substrate and molecular oxygen.

Bit, Tool (cutter)

(english) A hardened steel bar or plate that is shaped accordidng to the operation to be performed and the material to be machined.

Bright Basic Wire

(english) Bright steel wire, slightly softer than Bright Bessemer Wire. Used for round head wood screws, bolts and rivets, electric welded chain, etc.

Web engineering

(Software Engineering) the application of software engineering principles, concepts, and methods (or adaptations of them) to the development of Web-based applications or systems.

Bend Test

(english) Various tests which is used to ascertain the toughness and ductility of a metal product, in which the material is bent around its axis and/ or around an outside radius. A complete test might specify such a bend to be both with and against the direction of grain. For testing, samples should be edge filed to remove burrs and any edgewise cracks resulting from slitting or shearing. If a vice is to be employed, then you must line the jaws with some soft metal, to permit a flow of the metal in the piece being tested.

Black Oil Tempered Spring Steel Strip (Scaleless Blue)

(english) A flat cold rolled usually .70/.80 medium high carbon steel strip, blue-black in color, which has been quenched in oil and drawn to desired hardness. While it looks and acts much like blue tempered spring steel and carries a Rockwell hardness of C44/47, it has not been polished and is lower in carbon content. Used for less exacting requirements than clock spring steel, such as snaps, lock springs, hold down springs, trap springs, etc. It will take a more severe bend before fracture than will clock spring, but it does not have the same degree of spring-back.

Abrasive 1

(english) Material for grinding, polishing, blasting, either in loose form or bonded to form wheels, bricks, or files, or applied to paper and cloth by glue or resin. Natural abrasives include emery, corundum, garnet, sand, flint, etc. Metallic shot and grit are also used as abrasives in cleaning castings
