What is the abbreviation of concrete? What is the code name for concrete?

Concrete, for short"Concrete (tóng)."。Concrete refers to cement as the main cementitious material.

It is an artificial stone made of water, sand and gravel, mixed with chemical admixtures and mineral admixtures if necessary, matched in appropriate proportions, and hardened by uniform stirring, dense molding and curing.

Concrete is mainly divided into two stages and states: the plastic state before setting and hardening, that is, fresh concrete or concrete mixture; The hard state after hardening, i.e., hardened concrete or concrete.

Concrete strength grade.

It is the compressive strength of the cube.

The standard value is divided into 14 grades of ordinary concrete strength in China: C15, C20, C25, C30, C35, C40, C45, C50, C55, C60, C65, C70, C75 and C80.

Concrete. concrete, tóng, the word for concrete. In engineering design and construction, the word "concrete" is often abbreviated as "concrete".

The creator of the word "concrete" is Professor Cai Fangyin, a famous structural scientist. The date of creation is 1953. At that time, the teaching technology was backward, there were no tape recorders or photocopiers, and students relied on taking notes in class.

"Concrete" is the most commonly used word in construction engineering, 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 note-taking.

Later, "artificial stone" was synthesized into "concrete". The shape will mean "synthetic stone, concrete is as hard as stone". And it is promoted among college students.

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.

Concrete is referred to as concrete, commonly known as artificial stone.

Concrete tong two sounds can be typed out, but you have to read concrete.

The symbols of concrete are all represented by C, which is the abbreviation of English concrete.

If it's a legend, you can press :

1. Concrete is represented by "point irregular triangle" in the drawing.

2. Reinforced concrete is used in the drawings with "oblique dots, irregular triangles".

What is the abbreviation of concrete?

1.Concrete. 2.Burn.

Correct answer: 砼砼, the Chinese word Chihe, pinyin tóng, is a synonym for concrete. In engineering design and construction, the code wheel often abbreviates the word "concrete" as "concrete". The creator of the word "concrete" is Professor Cai Fangyin, a famous structural scientist.

Yes.

Concrete refers to the artificial stone made of cement as the main cementitious material, mixed with water, sand and gravel, mixed with chemical admixtures and mineral admixtures when necessary, matched in appropriate proportions, and hardened by uniform stirring, dense molding and curing. It is widely used in civil engineering.

Features:

Concrete has the characteristics of abundant raw materials, low cost and simple production process, so that the amount of concrete is getting larger and larger. At the same time, concrete also has the characteristics of high compressive strength, good durability and wide range of strength grades. These characteristics make it widely used, not only in various civil engineering projects, but also in shipbuilding, machinery industry, marine development, geothermal engineering, etc., concrete is also an important material.

Concrete is referred to as concrete. The concrete character was created by the famous structural scientist Professor Cai Fangyin in 1953, and in engineering design and construction, concrete is often abbreviated as concrete, which is widely used in various types of construction engineering books and periodicals.

Concrete refers to cement concrete obtained by mixing cement as cementitious material, sand and stone as aggregates, and water (which can contain admixtures and admixtures) in a certain proportion to obtain cement concrete, which can also be called ordinary concrete.

Concrete has a wide range of uses, and is widely used in civil engineering, that is, shipbuilding, mechanics, marine development, geothermal engineering, etc.

Concrete can be divided into structural concrete, thermal insulation concrete, decorative concrete, waterproof concrete, refractory concrete, hydraulic concrete, marine concrete, road concrete, radiation-proof concrete, etc.

Concrete is referred to as "concrete", which is a general term for engineering composite materials that combine aggregate glue into a whole by cementitious materials. Concrete materials mainly include cement, sand and gravel and other materials through a certain proportion of the mixture, concrete has the characteristics of abundant raw materials, low quality, simple production process and so on.

Workability is the most important function of concrete mixture, comprehensive expression of the consistency of the mixture, fluidity, plasticity, easy to wipe the characteristics of the mixture, there are many ways to determine the workability of the mixture, the most common is to use the truncated cone slump as an index of consistency.

Strength is the most important mechanical property of concrete after hardening, and key simplicity refers to the performance of concrete against gravity, tensile force and deformation. The ratio of cement, lime and other aggregates can affect the strength of concrete.

In general, concrete has good durability, and the building with good durability can still stand for a hundred years, but if it is in a cold area, the durability of concrete is relatively poor, and the concrete is easily damaged in a freeze-thaw state for a long time.

concrete, aka"Concrete (tóng)."

It refers to the general term of engineering composite materials that 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 when it is mixed with water (which can contain admixtures and admixtures) in a certain proportion and is mixed to obtain cement concrete.

Concrete is referred to as concrete, pronounced tóng, bridge code means concrete, in engineering design and construction, often abbreviated as concrete, the word concrete is the famous structural scientist Professor Cai Fangyin created in 1953, concrete is widely used in all kinds of construction engineering books.

Ready-mixed concrete is in a state of flux molding in a certain period of time, poured into the mold, tamped and liquefied to make structures or components of various shapes and sizes, and the cement and water undergo hydration reaction for a period of time after molding.
