Every concrete station is called "concrete" Why?

In fact, this word is a self-made word, which was originally simplified by the construction industry because it was too troublesome. Later, it was recognized as a word by the state. It's actually a word, a symbol. This symbol symbolizes the meaning of concrete. The concrete station is called "concrete". Because it is convenient and very practical, people who study architecture can understand it whether writing contracts or communicating at ordinary times, so in this case, the word is actually like a unique symbol of the construction industry.

In the past, when we were engaged in engineering, there was no computer, and all the design materials needed to be handwritten, so the utilization rate of concrete was very high. However, the word concrete appears frequently and is difficult to write, so Cai Fangyin, a structural expert, used artificial stone instead of concrete when writing concrete. Concrete is just artificial stone. But the artificial stone is just a little simpler to write, and it still takes up a lot of space, so it was later merged into one word, specific.

Concrete really often appears in the construction industry, especially in many material documents. Another reason is that the artificial stone "concrete" will appear later because of the high frequency and troublesome mistakes.

After reading the word "Tong" for the second time, because there are many things to be filled in at the construction site and "concrete" will also appear on the documents, people at the construction site use "concrete" instead of "concrete" for the convenience of writing, so it is not good to solve the problem of three words with one word.
