แปลว่า(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.

Facultative

แปลว่า(Environmental Engineering) A group of microorganisms which prefer or preferentially use molecular oxygen when available, but are capable of suing other pathways for energy and synthesis if molecular oxygen is not available.

Go, no-go decision

แปลว่า(Software Engineering) a point at which manager or the customer decides whether the project should proceed

Groundwater

แปลว่า(Environmental Engineering) Water which is contained in geologic strata. Also properly written as two words, ground water.

Photoautotrophic

แปลว่า(Environmental Engineering) Organisms which utilize inorganic carbon dioxide for protoplasm synthesis and light for an energy source. See autotrophic and chemoautotrophic.
