Blaine Fineness

แปลว่า(Concrete Engineering) The fineness of granular materials such as cement and pozzolan, expressed as total surface area in square centimeters per gram, determined by the Blaine air-permeability apparatus and procedure.

Bleeding, Bleed Water

แปลว่า(Concrete Engineering) A form of segregation in which some of the water in a mix tends to rise to the surface of freshly placed concrete. Known also as water gain.

Bright Drawing

แปลว่า(english) The process of drawing hot rolled steel through a die to impart close dimensional tolerances, a bright scale free surface and improved mechanical properties. The product is termed bright steel.

Greenhouse gases

แปลว่า(Environmental Engineering) Gases which trap solar radiation. Of the solar energy entering the earth's atmosphere a portion is reflected back and a portion penetrates onto the earth's surface. The portion reflected back from the earth's surface is at a different wavelength that when it entered. Carbon dioxide and other gases, which pass solar radiation, absorb this reflected radiation, increasing the earth's temperature. This is much like a greenhouse, hence the name.

Abrasion 1

แปลว่า(english) The displacement and/or detachment of metallic particles from a surface as a consequence of being exposed to flowing solids, fluids or gases. The process of rubbing, grinding, or wearing away by friction.

Troposphere

แปลว่า(Environmental Engineering) The lower atmosphere, from the earth's surface to approximately 12 km. This portion of the earth's atmosphere contains about 95 percent of the atmospheric gases. The temperature gradually declines through this region.

Stucco

แปลว่า(Concrete Engineering) A portland cement mortar material that can be applied to the surface of any building or structure to form a hard and durable covering for the exterior wails or other exterior surfaces.

Change of State

แปลว่า(Concrete Engineering) The process whereby liquid is heated to the point of evaporation changing the liquid into a gas the condensation of a gas on a cooler surface returning it from gaseous to liquid form.

Breaker

แปลว่า(english) Uncoiler rolls through which the strip passes; composed of a mandrel and leveling rolls which unwind the strip prior to processing through the Pickler. Breaker rolls assist in breaking up the Hot Mill surface scale.

area, catchment

แปลว่าพื้นที่ลุ่มน้ำ : 1. พื้นที่ซึ่งเมื่อฝนตกลงมาแล้ว น้ำจะไหลรวมกันลงสู่แม่น้ำ ทะเลสาบ หรืออ่างเก็บน้ำนั้นๆ 2. พื้นที่ที่มีผิวลาดชัน ซึ่งจะระบายน้ำจากเส้นสันปันน้ำ (divide) ไหลลงสู่ที่ระบายน้ำ (drainage basin) ตั้งแต่สองแห่งหรือมากกว่าขึ้นไป 3. พื้นที่ที่มีการล้อมรอบตัวเองด้วยสันปันน้ำ 4.พื้นที่เหนือจุด ๆ หนื่งบนลำธารที่มีการระบายน้ำผ่านจุดนั้น

Saponification

แปลว่า(Concrete Engineering) The deposit of a gray scum or gray dust on the inside surface of a subgrade wall or floor; as the result of moisture moving through the concrete and washing certain chemicals from the concrete mass.

Colloids

แปลว่า(Environmental Engineering) Small particles which have a negligible settling velocity. These particles have a very small mass so gravitational force is low compared to surface frictional forces. Typical colloidal sizes range from 10-3 mm to 1 mm.
