(english) "Fine particles of limestone (flux) and iron ore are difficult to handle and transport because of dusting and decomposition, so the powdery material usually is processed into larger pieces. The raw material's properties determine the technique that is used by mills. 1) SINTER Baked particles that stick together in roughly one-inch chunks. Normally used for iron ore dust collected from the blast furnaces. 2) PELLETS Iron ore or limestone particles are rolled into little balls in a balling drum and hardened by heat. 3) BRIQUETTES Small lumps are formed by pressing material together. Hot Iron Briquetting (HBI) is a concentrated iron ore substitute for scrap for use in electric furnaces.
(Concrete Engineering) Having cement-like, cementing, or bonding type properties. Material or substance producing bonding properties or cement-like materials.
(Concrete Engineering) Method of maintaining sufficient internal humidity and proper temperature for freshly placed concrete to assure proper hydration of the cement, and proper hardening of the concrete.
(english) (1) A semi-finished section hot rolled from a metal ingot, with a rectangular cross section usually ranging from 16 to 36 in., the width being less than twice the thickness. Where the cross section exceeds 36 in., the term “bloom” is properly but not universally used. Sizes smaller than 16 in. are usually termed “bars”; a solid semi-finished round or square product which has been hot worked by forging, rolling, or extrusion. (2) A semi-finished, cogged, hot rolled or continuous-cast metal product of uniform section, usually rectangular with radiused corners. Billets are relatively larger than bars.

(Concrete Engineering) A property of a solid that indicates its ability to withstand bending.
(english) A force-displacement relationship which is both linear and elastic. For a structure, this means the deformation is proportional to the loading, and deformations disappear on unloading. For a material, the concept is the same except strain substitutes for deformation, and stress substitutes for load.
