Colloids

แปลว่า(Environmental Engineering) Small particles which have a negligible settling velocity. These particles have a very small mass so gravitational force is low compared to surface frictional forces. Typical colloidal sizes range from 10-3 mm to 1 mm.

Elastic:

แปลว่า(english) A material or structure is said to behave elastically if it returns to its original geometry upon unloading.

Bonderized Coating

แปลว่า(english) A thin film of phosphate pretreatment applied to a steel surface (bare or zinc coated) to enhance paintability.

Transit-Mixed Concrete

แปลว่า(Concrete Engineering) Concrete produced from a central-batching plant, where the materials are proportioned and placed in truck-mixers for mixing enroute to the job or after arrival there.

Temper

แปลว่า(Concrete Engineering) The addition of water to the cement mix whether at the batch plant, during transit or at the jobsite to achieve the specified water to cement ratio.

Carbonation

แปลว่า(Concrete Engineering) 1) Reaction between the products of portland cement (soluble calcium hydroxides), water and carbon dioxide to produce insoluble calcium carbonate (efflorescence). 2) Soft white, chalky surface dusting of freshly placed, unhardened concrete caused by carbon dioxide from unvented heaters or gasoline powered equipment in an enclosed space. 3) Carbonated, dense, impermeable to absorption, top layer of the surface of concrete caused by surface reaction to carbon dioxide. This carbonated layer becomes denser and deeper over a period of time. 4) Reaction with carbon dioxide which produces a slight shrinkage in concrete. Improves chemical stability. Concrete masonry units during manufacturing may be deliberately exposed to carbon dioxide after reaching 80% strength to induce carbonation shrinkage to make the units more dimensionally stable. Future drying shrinkage is reduced by as much as 30%.

Belly Roll

แปลว่า(english) Roll used on the line to steady plate.

Cybernetic

แปลว่า(Environmental Engineering) Systems which change in response to feedback.

Acid Embrittlement

แปลว่า(English) Embrittlement during pickling due to absorption of hydrogen.

Classic life cycle

แปลว่า(Software Engineering) a linear, sequential approach to process modeling

Outsourcing

แปลว่า(Software Engineering) contracting software work to a third party

Bamboo Grain Structure

แปลว่า(english) A structure in wire or sheet in which the boundaries of the grains tend to be aligned normal to the long axis and to extend completely through the thickness.
