BURST PRESSURE

แปลว่า(english) The level of pressure at which a component, pipe, tube, hose or other fluid passage will burst during application of internal pressure. Normally 2.5 - 4.0 times working pressure.

Flocculant settling

แปลว่า(Environmental Engineering) Settling in which particle concentrations are sufficiently high that particle agglomeration occurs. This results in a reduction in the number of particles and an increase in average particle mass. As agglomeration occurs higher settling velocities result.

Phototroph

แปลว่า(Environmental Engineering) Organisms which obtain energy from light using photooxidation.

Anoxic process

แปลว่า(Environmental Engineering) A process which occurs only at very low levels of molecular oxygen or in the absence of molecular oxygen.

Compression settling

แปลว่า(Environmental Engineering) Settling which occurs in the lower reaches of clarifiers where particle concentrations are highest. Particles can settle only by compressing the mass of particles below.

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.

ASR - Alkali-Silica Reactivity

แปลว่า(Concrete Engineering) The reaction of aggregates, which contain some form of silica or carbonates with sodium oxides or potassium oxides in cement, particularly in warm, moist climates or environments, causing expansion, cracking or popouts in concrete.

Pozzolan (ASTM C 618)

แปลว่า(Concrete Engineering) A siliceous, or siliceous and aluminous material, which in itself possesses little or no cementitious value but will, in a finely divided form, such as a powder or liquid and in the presence of moisture, chemically react with calcium hydroxide at ordinary temperatures to form permanent, insoluble compounds possessing cementitious properties.

Facultative

แปลว่า(Environmental Engineering) A group of microorganisms which prefer or preferentially use molecular oxygen when available, but are capable of suing other pathways for energy and synthesis if molecular oxygen is not available.
