What does commercial concrete mean, what does commercial concrete mean!

Commercial concrete is commercial concrete, called ash or material: it is a concrete mixture that is transported to the place of use within a specified time by means of cement, aggregate, water and admixtures and other components mixed according to a certain proportion in the mixing station after being measured and mixed and transported by a transport vehicle. Concrete, pinyin as tóng, is the consent word for concrete.

In engineering design and construction, the word "concrete" is often abbreviated as "concrete". Created in 1953 by the famous structural scientist Professor Cai Fangyin, on June 7, 1985, the Chinese Character Reform Committee officially approved the synonym of "concrete" and "concrete".

Commercial concrete refers to concrete used for commercial purposes, such as concrete that can be purchased and purchased. At present, most of the construction uses commercial concrete.

A general term for engineering composite materials in which aggregates are cemented into a whole by cementitious materials. The word "concrete" usually refers to the use of cement as cementitious material, sand and stone as aggregates;Cement concrete, also known as ordinary concrete, is widely used in civil engineering engineering by mixing, forming and curing in a certain proportion with water (with or without admixtures and admixtures).

Commercial concrete means commercial concrete. Commercial concrete (tóng) is commercial concrete. Created in 1953 by the famous structural scientist Professor Cai Fangyin, on June 7, 1985, the Chinese Character Reform Committee officially approved the synonym of "concrete" and "concrete".

Commercial concrete refers to concrete that is produced in a specialized concrete ready mix plant and is used as a commodity. It was created by the famous structural scientist Professor Cai Fangyin, and later spread and was officially recognized.

Commercial concrete, also known as ready-mixed concrete, referred to as "commercial concrete", commonly known as ash or concrete: it is a concrete mixture that is transported to the place of use within a specified time by cement, aggregate, water and admixtures and mineral admixtures mixed according to a certain proportion in a commercial concrete mixing station.

The emergence of "commercial concrete" is because of today's various engineering construction projects, the technical requirements for concrete are different, if there is non-standard concrete mixed into the market, it is bound to cause major quality accidents. For example, large concrete dams, super high-rise buildings, etc., have very high requirements for the control of technical indicators of concrete, and manual mixing is never allowed.

The finished products produced by the concrete company and sold to the construction unit are called commercial concrete, referred to as commercial concrete.

It's commercial concrete. It refers to the cement concrete mixed by the mixing plant.

There is no difference between the two, they mean the same thing.

1. Commercial mixing. Commercial concrete, that is, commercial concrete, also known as ready-mixed concrete, refers to cement concrete obtained by mixing, forming and curing cement concrete, also known as ordinary concrete, which is widely used in civil engineering engineering with cement as cementitious material, sand and stone as aggregates, and water (with or without admixtures and admixtures) in a certain proportion.

Second, commercial concrete. Commercial concrete, refers to commercial concrete. Concrete was created in 1953 by Professor Cai Fangyin, a famous structural scientist, and on June 7, 1985, the Chinese Character Reform Committee officially approved the synonym of concrete and concrete.

Sand is a finished product sold to the construction unit according to the mix ratio (generally provided by the local testing unit), referred to as commercial concrete.

Self-mixed concrete, the full name of commercial concrete, is produced by concrete companies, and they use cement by themselves.

Commercial concrete is commercial concrete, created in 1953 by the famous structural scientist Professor Cai Fangyin, on June 7, 1985, the Chinese Character Reform Committee officially approved the synonym of "concrete" and "concrete".

"Concrete" is synonymous with "concrete", especially the colleagues who are engaged in infrastructure construction probably know this word, we will talk about what commercial concrete means today.

01 Commercial concrete is commercial concrete, created in 1953 by the famous structural scientist Professor Cai Fangyin, on June 7, 1985, the Chinese Character Reform Committee officially approved the synonym of "concrete" and "concrete".

02 The creator of the word "concrete" is Professor Cai Fangyin, a famous structural scientist, who created it in 1953 and has been 60 years so far. At that time, the teaching technology was backward, there were no tape recorders, and there were no photocopiers......Students take notes in class. "Concrete" is the most commonly used word in construction work, but there are too many strokes, and it is laborious and time-consuming to write!

So Cai Fangyin, who was quick-witted, boldly replaced "concrete" with the word "artificial stone". Because there are 30 strokes of the word "concrete", and only 10 strokes of the word "artificial stone", it can save 20 strokes and greatly speed up the speed of notes! Later, "artificial stone" was synthesized into "concrete"!

And it has been promoted among college students, one to ten, ten to hundred.

03 In July 1955, in the book "Structural Engineering Terminology" approved and promulgated by the "Terminology Room" of the Compilation and Publication Committee of the Chinese Academy of Sciences, it was clearly recommended that the words "concrete" and "concrete" should be used together. Since then, "concrete" has been widely used in all kinds of construction engineering books.

On June 7, 1985, the Chinese Character Reform Committee officially approved the legal status of "concrete" and "concrete" being used synonymously and together.
