What to read specifically?

Concrete, that is, concrete, is the most commonly used word in engineering. This word is short for concrete. The word concrete was coined by Professor Cai Fangyin, a famous structuralist, in 1953.

Concrete (tóng) stands for concrete, which is very intuitive. In fact, if you think about it carefully, isn't concrete a material that is artificially made as hard as stone? If you take the concrete apart, it is an artificial stone. Therefore, using this word to represent concreteness is simply a vivid thing, and it is convenient to write, saving paper and ink!

But the word can stand for concrete. If you read it, you'd better read it concretely, otherwise it will make you laugh.

For example, in construction, it is often said that 100 cubic meters of concrete is needed, or that 100 cubic meters of lime is needed for commodity mixing, but you must never say that 100 cubic meters of concrete (Tó ng) is needed; For another example, you can write a commercial concrete station and read it as a commercial mixing station or a commercial concrete station. You can't read it as a commercial concrete (tóng) station, or the people who hear it will know that you are an engineering white. So, don't tell me any jokes about 100 cubic meter of commercial concrete (tóng) in the future!

The origin of the word concrete is also very interesting. Because of the backward technology in the 1950s, there were no tape recorders and photocopiers, so students had to take notes in class. There are too many strokes in the word concrete, which is laborious and time-consuming to write.

So Cai Fangyin, who is quick-thinking (not good at being lazy), creatively used the word concrete, not the word concrete. There are thirty pens of cement and only ten pens of artificial stone, which can save twenty pens and greatly speed up the speed of taking notes. Configuration will mean "synthetic stone, concrete is as hard as stone".

The origin of concrete:

The creator of the word "concrete" is Professor Cai Fangyin, a famous structuralist. The creation time is 1953. Pronunciation is the same as "Tong", mainly for the convenience of simple and quick spelling or reading "concrete" in construction engineering. "Concrete" is a cognitive word, which means "artificial stone, that is, concrete".
