Calcine

แปลว่า(Concrete Engineering) To alter composition or physical state by heating to a specific temperature for a specific length of time.

altimeter

แปลว่าเครื่องวัดระดับ หรือระยะความสูงจากพื้นโลก

gain time

แปลว่ายึดเวลา, ประวิงเวลา

save time and labour

แปลว่าทุ่นเวลา และแรงงาน, ประหยัดเวลาและแรงงาน

Wetland

แปลว่า(Environmental Engineering) Semi-aquatic land, that is land that is either inundated or saturated by water for varying periods of time during each year, and that supports aquatic vegetation which is specifically adapted for saturated soil conditions.

setting time

แปลว่าเวลาก่อตัว

Baked Core

แปลว่า(english) A core which has been heated through sufficient time and temperature to produce the desired physical properties attainable from its oxidizing or thermal-setting binders.

Internal force:

แปลว่า(english) Forces which hold an object together when external forces or other loads are applied. Internal forces are sometimes called resisting forces since they resist the effects of external forces.

Deflection:

แปลว่า(english) This word usually carries the same meaning as displacement, although it is sometimes used in place of deformation.

Hydrogenesis

แปลว่า(Concrete Engineering) Another term for condensation. The term is especially applied to base and soil substrates under highway pavements. where the barometric pump causes the inhalation of humid air, which then condenses in those structures, causing an ever increasing moisture content and sometimes instability.

joint, construction

แปลว่ารอยต่อก่อสร้าง : รอยต่อที่กำหนดไว้ในงานคอนกรีตใน 1 วัน ใช้กับอาคารขนาดใหญ่ ซึ่งต้องเทคอนกรีตจำนวนมากติดต่อกัน และระยะเวลาที่ใช้ในการเทคอนกรีตนั้นเกินกว่าระยะเวลาการแข็งตัวของคอนกรีต (initial setting time)

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%.
