There is no difference between the two words, both refer to commercial concrete. Commercial concrete, also known as ready-mixed concrete, is prone to deformation, expansion or formwork explosion, large amount of slurry, good workability and fast construction because of its high lateral pressure on formwork. Figurative figures were created by Mr. Cai Fangyin in 1953, with a history of 60 years. At that time, educational technology was still very backward. There are no tape recorders and photocopiers, and students take notes in class. In building engineering, concrete is the most commonly used, but it takes time to write because of the long strokes. Therefore, Cai Fangyin boldly changed cement into "artificial stone". Cement has only 30 Chinese characters, and artificial stone has only 10 Chinese characters, which can save 20 small holes and is very efficient. Later, artificial stone and concrete were mixed together and widely used among college students. 1On June 7th, 985, China Language Reform Commission officially approved the legal names of concrete and concrete.

What are the advantages of commercial mixing? 1. can improve the construction quality. Due to the stable raw materials, advanced technology, computer control, accurate measurement, perfect detection means, stable quality, durability and high strength, the quality of buildings (structures) has been effectively improved.

2. It can greatly shorten the construction period and speed up the construction progress. Construction enterprises use commodity mixing to speed up the construction and reduce the turnover lease cost of equipment and templates. The project owner can shorten the construction time and reduce the project investment risk.

3. The material loss can be reduced. The consumption of sand, gravel and cement is huge. Generally, the field mixing is 15% to 30%, and the cement loss is 10%.

4. It can save the building area. Because the quality of commercial mixture is stable and stable, the design unit designs according to the adopted commercial mixture, which can effectively avoid the phenomenon of "fat beam, fat column and thick plate" and save a lot of design resources.

5, can improve and improve the performance of concrete. The use of mineral admixtures such as mineral powder and fly ash in commercial mixing can improve the waterproof, crack-resistant and wear-resistant properties of concrete and prolong its service life.

6. The total cost can be reduced.

That's what I told you about the difference between business mixing and business mixing. I hope I can help you. If you don't know much about it, you can refer to the above content to learn.
