If you hold your ground, then you might have a chance
หมวดถ้าคุณไม่ถอยคุณก็อาจจะมีโอกาส
Groundwater
แปลว่า(Environmental Engineering) Water which is contained in geologic strata. Also properly written as two words, ground water.
Keep your eyes on the stars, and your feet on the ground
Dump
แปลว่า(Environmental Engineering) An illegal and uncontrolled area where wastes have been placed on or in the ground. See Landfill.
base flow
แปลว่า1. น้ำที่ไหลในลำน้ำเกิดจากการไหลซึมออกมาของน้ำใต้ดิน ส่วนมากเกิดในช่วงฤดูแล้ง เป็น ground water runoff 2. ปริมาณน้ำเดิมที่ไหลอยู่ในลำน้ำก่อนเกิดน้ำท่า
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.
Sulfate Attack
แปลว่า(Concrete Engineering) Deleterious chemical and/or physical re-action between sulfates in ground water or soil and certain constituents in cement, which result in expansion and disruption of the concrete.
Cement, Portland (ASTM C150) (Concrete Engineering)
แปลว่าA powdery substance made by burning, at a high temperature, a mixture of clay and limestone producing lumps called “clinkers” which are ground into a fine powder consisting of hydraulic calcium silicates. For non-portland cements, see aluminous cement.
Back Rake
แปลว่า(english) The angular surface ground back from the cutting edge of cutting tools. On lathe cutting tools. The rake is positive if the face slopws down from the cutting edge toward the shank, and negative if the face sloopes upward toward the shank.
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%.
