Brinell Hardness Test

(english) A common standard method of measuring the hardness of materials. The smooth surface of the metal is subjected to indentation by a hardened steel ball under pressure. The diameter of the indentation, in the material surface, is then measured by a microscope and the hardness value is read from a chart or determined by a prescribed formula.

Blue Annealing

(english) Heating hot rolled ferrous sheet in an open furnace to a temperature within the transformation range and then cooling in air, in order to soften the metal. The formation of a bluish oxide on the surface is incidental.

Dry Rodded Weight

(Concrete Engineering) The weight of dry aggregate rodded into a cylindrical container of diameter approximately equal to the height, each of 3 layers rodded 25 times, and the excess aggregate struck off level with the top of the container

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.

Mixed liquor volatile suspended solids (MLVSS)

(Environmental Engineering) The volatile suspended solids concentration in the activated sludge tank.

Jacking Equipment

(Concrete Engineering) In prestress concrete, the device used to stress the tendons.

Mixed liquor suspended solids (MLSS)

(Environmental Engineering) The total suspended solids concentration in the activated sludge tank.

Stability:

(english) Stability is best defined as the opposite of instability, which is the occurrence of large structural deformations which are not the result of material failure.

Discrete settling

(Environmental Engineering) Settling in which individual particles settle independently, neither agglomerating or interfering with the settling of the other particles present. This occurs in waters with a low concentration of particles.

Nitrogenous oxygen demand (NOD)

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

Biogeochemical cycle

(Environmental Engineering) The cycle of elements through the biotic and abiotic environment.
