หรือคุณกำลังค้นหา permeable, permeable strata
permeable strata
แปลว่าปีกดินคานซึ่งอยู่เป็นชั้นๆ ที่น้ำไหลซึมทะลุลงไปได้
permeable
แปลว่าซึ่ง (น้ำ) ไหลซึมเข้าไปได้
แปลว่าซึมผ่านได้, แผ่ซ่านได้, ซึมแทรกได้
Impermeable
แปลว่า(Concrete Engineering) The ability of a material or product to reduce or eliminate gaseous transmissions through it's mass; measured as the rate of Water Vapor Transmission (WVT). Note: Not all materials that are waterproof are vaporproof; all materials that are vaporproof are inherently waterproof.
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%.
impermeable
แปลว่าซึ่งซึมผ่านไม่ได้, ซึ่งไม่สามารถผ่านได้
