Calcium chloride
| Глоссарий по архитектуре и конструкциям |
- A chemical salt used in plastic concrete as an accelerator.
- A soluble salt, cacl2, commonly added to cement in small amounts to hasten its setting and also dissolved in water to produce a freeze-resistant drilling circulation fluid.

Calcium, английский
- Calcio
- A metallic chemical element which is a major component of bones and teeth and which is essential for various bodily processes such as blood clotting (note: the chemical symbol is ca.) comment: calcium is an important element in a balanced diet. milk, cheese, eggs and certain vegetables are its main sources. calcium deficiency can be treated by injections of calcium salts.
- Кальций
Calcium -, английский
- Гидроксид кальция
- Кальциевая жёсткость (воды)
Calcium action potential, английский
Calcium aluminate cement., английский
Calcium aluminate cement. aluminum, brit. aluminium a lustrous, silver-white, nonmagnetic, lightweight metal which is very malleable; has good thermal and electrical conductivity; a good reflector of both heat and light. in construction, most aluminum is, английский

Calcium antagonist, английский
A drug which makes the arteries wider and slows the heart rate. it is used in the treatment of angina.
Calcium autunite, английский
Calcium carbide, английский
A crystalline solid, cacs, colorless when pure but often resembling gray limestone. it is made by heating lime and carbon together in an electric furnace. water added to the product causes acetylene to be generated, and this is used as an illuminating gas in drillers or miners lamps or as a fuel burned with oxygen to produce the hot flame of welding and cutting torches. also called carbide.
Calcium carbonate, английский
- Caco3
- A low-density white pigment for use in paint; provides little opacity; used mainly to provide bulk and flatness.
Calcium channel blocker, английский
A drug which affects the smooth muscle of the cardiovascular system, used in the treatment of angina and hypertension (note: calcium channel blockers have names ending in -dipine: nifedipine. not to be used in heart failure as they reduce cardiac function further.)
Calcium chloride process, английский
Calcium complex grease, английский
See complex greases.
Calcium deficiency, английский
A lack of calcium in the bloodstream
Calcium feldspar, английский
Calcium fluoride, английский

Accelerator, английский
- Ускоритель
- Ускоритель; ускоряющий электрод; катализатор; катапульта (авианосца)
- Any substance that when added to a cement, such as calcium chloride added to portland cement, shortens its normal setting time.
- Device controlling the rate at which fuel is injected into a combustion-type engine and hence controlling its speed. also called throttle.
- A type of browser extension that gives users quick access to their web and client applications from any web page. an accelerator can run on user-selected data, links, and the current document. this browser extension can provide -€oelookup-€? service like in-place definition or -€oesend-€? service like sending selected text to a web e-mail provider.
- Pedal by which the fuel flow to the engine is controlled, depression of the pedal causing the vehicle to accelerate.
- A device that accelerates charged atomic particles to high energies. an x-ray machine or a betatron is an accelerator.
- (1) device that accelerates charged particles to high energies. examples are x-ray tubes, linear accelerators, and betatrons. (2) linear accelerator.
- (1) устройство, ускоряющее заряженные частицы до высоких энергий. примерами являются рентгеновские трубки, линейные ускорители и бетатроны. (2) линейный ускоритель.
Circulation, английский
- Циркуляция
- Circulation (of the blood) movement of blood around the body from the heart through the arteries to the capillaries and back to the heart through the veins she has poor circulation in her legs. rub your hands to get the circulation going. comment: blood circulates around the body, carrying oxygen from the lungs and nutrients from the liver through the arteries and capillaries to the tissues. the capillaries exchange the oxygen for waste matter such as carbon dioxide which is taken back to the lungs to be expelled. at the same time the blood obtains more oxygen in the lungs to be taken to the tissues. the circulation pattern is as follows: blood returns through the veins to the right atrium of the heart. from there it is pumped through the right ventricle into the pulmonary artery, and then into the lungs. from the lungs it returns through the pulmonary veins to the left atrium of the heart and is pumped from there through the left ventricle into the aorta and from the aorta into the other arteries.
- The passing of any liquid or gas to the end of the drill string and back to the surface in the process of drilling a borehole.
- The movement of air currents through mine openings.
- An item that is communicated to team members on a group work site, and that supports confirmation and tracking of which team members have viewed it. cisc (n)
- Caused by quick changes in pressure, cavitation is the creation of vapor cavities within a low-pressure liquid. cavitation can cause severe wear through cyclic stress on metal surfaces as they implode.

Bonding agent, английский
A chemical substance applied to a suitable substrate to create a bond between it and a succeeding layer, as between a subsurface and a terrazzo topping or between a surface and the plaster that is applied to it.
Sulfate attack, английский
A chemical or physical reaction, or both, between sulfates (in ground water or in the soil) and concrete or mortar; primarily damaging to the cement paste matrix; reduced in concrete made with sulfateresistant cement.
