humidity
แปลว่าความชื้น (ในอากาศ)
relative humidity
แปลว่าความชื้นสัมพัทธ์
absolute humidity
แปลว่าความชื้นสัมบูรณ์
Cure
แปลว่า(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.
Vapor Pressure
แปลว่า(Concrete Engineering) The pressure exerted by a vapor that is calculated based upon relative humidity and temperature. The higher the humidity and higher temperature, in degrees Fahrenheit, the greater the vapor pressure exerted.
Moist Room
แปลว่า(Concrete Engineering) A room used for storing and curing cementitious test specimens. The atmosphere of this room is maintained at a temperature of 73.4 3.0'F or 23.0*1.7'0 and relative humidity of at least 98 percent. These facilities must be adequate to continually maintain free moisture on the exteriors of test specimens.
relative humidity (1)
แปลว่าความชื้นสัมพันธ์ : อัตราส่วนระหว่างความชื้นในอากาศขณะนั้น ต่อความชื้นของอากาศแห่งเดียวกันเมื่ออิ่มตัว แสดงอยู่ในรูปร้อยละ
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.
