(Concrete Engineering) A penetration device used to determine the setting characteristics of hydraulic cements.
(english) A cutting tool in which the tool bit,the boring bar and in some cases the tool holder are incorporated.
(Environmental Engineering) The amount of molecular oxygen dissolved in water.
(english) A very general term that may be applied to a material or a structure. In a material, strength refers to a level of stress at which there is a significant change in the state of the material, e.g., yielding or rupture. In a structure, strength refers to a level of level of loading which produces a significant change in the state of the structure, e.g., inelastic deformations, buckling, or collapse.
(english) The tendency of an object at rest to remain at rest, and of an object in motion to remain in motion.
(english) The standard steel pipe used in plumbing. Heated skelp is passed continuously through welding rolls, which form the tube and squeeze the hot edges together to make a solid weld.
(english) A force considered to act along a single line in space. Concentrated forces are useful mathematical idealizations, but cannot be found in the real world, where all forces are either body forces acting over a volume or surface forces acting over an area.
(english) A three-roll cluster used to control line tension at strategic locations on the line.
(english) A cavity which was produced during the solidification of metal by evolved gas, which in failing to escape is held in pockets.

(Concrete Engineering) A sand used as a standard in testing hydraulic cements by means of mortar test specimens. Sand is produced by processing silica rock particles obtained by hydraulic mining of the orthoquartzite situated in open-pit deposits near Ottawa, Illinois; naturally rounded grains of nearly pure quartz.
(Environmental Engineering) Water which is contained in lakes, rivers, and oceans.
