Q:What is the meaning of the word "concrete" in the concrete mixer jar?

"Concrete" is a synonym for "concrete". Everyone knows that, especially gay people who work in the construction of the gay community, probably know the word. But who created the concrete? When was it approved for general purpose? -- I'm afraid not! The creator of the word "concrete" is professor CAI fangyin, a prominent structural scientist. The creation time is 1953! 56 years to date. The teaching technology was backward, there was no tape recorder, no copiers... Students take notes in class. "Concrete" is the most commonly used word in construction projects, but there are too many strokes to write. Hence the thinking agile CAI fang Yin is bold to use "artificial stone" 3 words instead "concrete". Because "concrete" three words have 30 words, and "artificial stone" three words only ten, can save 20 pen, greatly speed up the note speed! Then "artificial stone" synthesized "concrete"! And they are promoted in college students. Published in July 1955, the compilation of the Chinese academy of sciences committee room "noun" examination and issued "structural engineering noun", explicitly recommend "concrete" and the word "concrete" and use. Since then, "concrete" has been widely used in the books and periodicals of various kinds of construction projects. On June 7, 1985, the Chinese language reform commission formally approved the "concrete" and "concrete" synonym and the legal status of the "concrete". In addition, the sound of the "concrete", tong (the same), happens to BE "bee-ton" in French. German "be-ton", Russian "Be - TOH

Q:Does it affect the ease of mixing too long?

The site stirring, the quality is not easy to control, the site pollution is serious for the main reason, the construction committee has the file request, so all do not stir in the scene.

Q:How many layers of steel wire tyres are used in concrete mixers

For example; 1200 the r20 pr M588 18 1200 is the outer circle size R is the radial tire 20 is the inner circle size, Should be 18PR!!!!!! This is the level of the wire in the tyre. M588 is the symbol of tire tire!! Concrete agitator truck tyres are usually used in 18 levels of steel wire tyres, which is used in 20 levels I'm selling tyres, I hope to help you

Q:s the collapse of four concrete mixer trucks

The degree of slump refers to the ease of concrete, which is specifically to ensure the normal operation of the construction, including the water retention, liquidity and cohesion of the concrete. Workability is refers to the concrete mixture is easy to operation, mixing, transportation, pouring and tamping), and uniform quality, compacted concrete performance. It is a comprehensive technical property, including water retention, liquidity and cohesion. The main factors of influence and ease are the water usage, the ratio of water ash ratio, the ratio of sand, including the variety of cement, aggregate condition, time and temperature, admixture and so on.

Q:What are the three main parts of the concrete mixer car

The three main parts of a concrete mixer are oil pump, motor and speed reducer. The function of oil pump: provide constant power for hydraulic oil. The function of the motor: converts the power of the hydraulic oil into mechanical power and is transmitted to the decelerator. Decelerator: reduce the speed of the hydraulic motor

Q:Is it possible to mix the concrete in a mixing truck for eight hours?

I think the main thing is to look at the state, but now the concrete is usually required to be discharged within four hours after the discharge (guangdong area).

Q:What is the purpose of the concrete mixer

It is the delivery of concrete!!! During the shipment, the tank continuously rotates and prevents concrete from solidifying. Once delivered, the concrete can be poured into the pump to get the concrete where it needs to be.

Q:How does the concrete mixing truck work?

Working principle is that by taking power device to take out car chassis power, and drive hydraulic system of the variable pump, the mechanical energy into hydraulic energy to quantitative motor, motor and drive reducer, driven by speed reducer mixing plant, for mixing concrete
