(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.
(english) A number of standard tests determined by American Foundrymen's Society to evaluate molding and core sands.
(Concrete Engineering) The increase of concrete temperature caused by heat of hydration and heat from other sources.
(english) Developing a smooth finish on a metal by tumbling or rubbing with a polished hand tool.

(english) The ratio of shear stress divided by the corresponding shear strain in a linear elastic material.
(Concrete Engineering) The water in concrete which is irremovable by oven drying; chemically combined during cement hydration.
(Concrete Engineering) Area or portion of hardened concrete which is deficient in mortar and consisting primarily of coarse aggregate and open voids; caused by insufficient consolidation or separation during placement, or both; by leakage from form.
(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.
