Band Wareroom

(english) A storage area in Strip Steel used for storing hot bands (coil made from slab).

Strength:

(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.

Sack

(Concrete Engineering) A quantity of cement: 94 Ibs. in the United States, 87.5 Ibs. in Canada, for portland or air entraining portland cement, or as indicated on the sack for other kinds of cement.

Pozzolan (ASTM C 618)

(Concrete Engineering) A siliceous, or siliceous and aluminous material, which in itself possesses little or no cementitious value but will, in a finely divided form, such as a powder or liquid and in the presence of moisture, chemically react with calcium hydroxide at ordinary temperatures to form permanent, insoluble compounds possessing cementitious properties.

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.

Screen (or Sieve)

(Concrete Engineering) A metallic sheet or plate, woven wire cloth, or similar device, with regularly spaced openings of uniform size, mounted in a suitable frame or holder for use in separating material according to size.

Receiving water quality standards

(Environmental Engineering) Standards which require a discharger to maintain a certain quality level in the receiving water.

Abrasion-Resistant Steels

(english) A family of steel products developed for those applications involved in sliding and/or impact abrasion.

Carbonaceous biochemical oxygen demand (CBOD)

(Environmental Engineering) The amount of oxygen required to oxidize any carbon containing matter present in a water.

Total solids

(Environmental Engineering) (TS) is the amount of organic and inorganic matter which is contained in a water.

Truck Mixer

(Concrete Engineering) A concrete mixer capable of mixing concrete in transit when mounted on a truck chassis.

Scalar:

(english) A mathematical entity which has a numeric value but no direction (in contrast to a vector).
