Carbonaceous biochemical oxygen demand (CBOD)
แปลว่า(Environmental Engineering) The amount of oxygen required to oxidize any carbon containing matter present in a water.
Chemical oxygen demand (COD)
แปลว่า(Environmental Engineering) The amount of oxygen required to oxidize any organic matter in the water using harsh chemical conditions.
Volatile solids
แปลว่า(Environmental Engineering) (VS) is the amount of matter which volatilizes (or burns) when a water sample is heated to 550EC.Volatile suspended solids
Performance Bond
แปลว่าหนังสือค้ำประกันการทำงานที่ผู้รับเหมาให้กับเจ้าของโครงการว่าจะทำงานและรับผิดชอบทุกสิ่งตามหน้าที่ของผู้รับเหมาและจะทำงานให้แล้วเสร็จตามที่ระบุในเอกสารสัญญา (เหมือน Contract Bond)
Water-Cement Ratio
แปลว่า(Concrete Engineering) The ratio of the amount of water, exclusive of that absorbed by the aggregates, to the amount of cement in a concrete mix. Typically expressed as percentage of water, by weight in pounds, to the total weight of portland cement, fly ash, and any other cementitious material, per cubic yard, exclusive of any aggregates.
Ultimate biochemical oxygen demand (BODu)
แปลว่า(Environmental Engineering) The total amount of oxygen required to oxidize any organic matter present in a water, i.e. after an extended period, such as 20 or 30 days.
Air Content
แปลว่า(Concrete Engineering) The amount of entrained or entrapped air in concrete or mortar, exclusive of pore space in aggregate particles, usually expressed as a percentage of total volume of concrete or mortar.
Maximum Size Aggregate
แปลว่า(Concrete Engineering) Aggregate whose largest particle size is present in sufficient quantity to affect the physical properties of concrete; generally designated by the sieve size on which the maximum amount permitted to be retained is 5 or 10 percent by weight.
Ductility:
แปลว่า(english) Ductility generally refers to the amount of inelastic deformation which a material or structure experiences before complete failure. Quantitatively, ductility can be defined as the ratio of the total displacement or strain at failure, divided by the displacement or strain at the elastic limit.
Water Vapor Pressure
แปลว่า(Concrete Engineering) The pressure exerted by water vapor. Air that contains higher amounts of water vapor exerts a higher vapor pressure than air which has a lower amount of has a higher water vapor pressure In concrete water vapor pressure is calculated by the difference between the vapor pressure of the concrete and the ambient relative humidity and temperature and in contact with the soil. that is calculated by; based upon relative humidity and temperature. The greater the difference between the water vapor and ambient humidity and temperature, in degrees Fahrenheit. the greater the water vapor pressure exerted.
