Entrapped Air
แปลว่า(Concrete Engineering) Air in concrete which is not purposely en-trained, Entrapped air bubbles are normally much larger and more irregular than entrained air bubbles.
purpose
แปลว่าวัตถุประสงค์
Couple:
แปลว่า(english) A system of forces composed of two equal forces of opposite direction, offset by a distance. A couple is statically equivalent to a moment whose magnitude equals the magnitude of the force times the offset distance.
four-cylinder opposed
แปลว่าเครื่องยนต์ชนิดสี่ชนิดสี่สูบตั้งตรงข้ามข้างละสองสูบ
Compound
แปลว่า(Environmental Engineering) A substance composed of two or more elements.
Structural model:
แปลว่า(english) An idealization for analysis purposes of a real or conceived structure. A structural model includes boundaries limiting the scope of the analysis. Supports occur at these boundaries, representing things which hold the structure in place.
exposed aggregate finish
แปลว่าหินล้าง, ทรายล้าง
Keene's Cement
แปลว่า(Concrete Engineering) A finely ground high density plaster composed of anhydrous, (calcined or "dead burned") gypsum, the set of which is accelerated by the addition of other materials.
repose angle
แปลว่ามุมลาดคงตัวของทรายและกรวด
multipurpose area
แปลว่าพื้นที่ที่มีประโยชน์มากมายหลายอย่าง
Hydrocarbon
แปลว่า(Environmental Engineering) Any organic compound composed entirely of carbon and hydrogen. Two examples are methane gas and octane.
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%.
