Zinc

แปลว่า(english) Chemical Symbol Zn. Element No. 30 of the periodic system; atomic weight 65.38. Blue-white metal; when pure, malleable and ductile even at ordinary temperatures; melting point 787 (degrees) F.; boiling point 1665 (degrees) F., specific gravity 7.14. Can be electrodeposited; it is extensively used as a coating for steel and sheet zinc finds many outlets, such as dry batteries, etc. Zinc-base alloys are of great importance in die casting. Its most important alloy is brass.

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.

Bath Annealing

แปลว่า(english) Is immersion is a liquid bath (such as molten lead or fused salts) held at an assigned temperature-when a lead bath is used, the process is known as lead annealing.

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.

Retempering

แปลว่า(Concrete Engineering) The addition of water and remixing of concrete which has started to stiffen: usually not allowed as it may affect the ultimate strength.

tempering

แปลว่า(โรงตีเหล็ก) การชุบเหล็กให้แข็ง

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.

Bake

แปลว่า(english) Heat in an oven to a low controlled temperature to remove gases or to harden a binder.

Baked Strength

แปลว่า(english) Compressive, shear, tensile or transverse strength of a mold sand mixture when baked at a temperature above 231 B0F (111 B0C) and then cooled to room temperature.

color for tempering

แปลว่าลักษณะของสีในการชุบเหล็ก, ซึ่งจะปรากฏสีดังต่อไปนี้, สีขาว, สีฟางข้าวอ่อน, สีฟางข้าวเข้ม, สีฟ้าและสีม่วง, การตรวจสอบสีในการชุบเป้นไปตามอันดับสี จนกระทั่งถึงสีแสดงความเข้มเท่าที่ต้องการ

Accm

แปลว่า(english) In hypereutectoid steel, the temperature at which cementite goes into complete solution with austenite.

Braze Welding

แปลว่า(english) A family of welding procedures where metals are joined by filler metal that has a melting temperature below the solidus of the parent metal, but above 840 (450 C).
