Cement is a kind of gray powder burned by a substance called lime, which is a wrapping material. It can be used to build buildings, lay walls or floor tiles, or build brick walls and bury D sand bricks or red bricks together, which has many uses. Concrete, commonly known as concrete, is a mixture of water, pebbles and sand, hence the name. I remember that there are three kinds of materials buried in ditches, so it seems that there is an existing name that is less used by people, called concrete. In other words, according to the general pragmatic habits of China and Hongkong people, cement is not only a powdery raw material, but also a synonym for built-in concrete, which is why you are confused. However, your problem is that in 1), concrete and concrete may be separated from each other in appearance. If cement refers to raw materials, you already know that one is powder, the other is debris flow without solidification, and after solidification, it is the structural material of buildings. If cement is a common name for concrete, they are the same thing. Alanwong said that the surface of concrete is smoother and more shiny than cement, which is debatable. His view is based on "cement is mud ditch and sea sand". There may be a few people in China and Hongkong who have this concept, but since you typed the word cement in English, you should interpret it according to its meaning. The English dictionary does not interpret it as "mud ditch and sea sand". 2) In fact, concrete is equivalent to adding cement to the left steel root? Generally speaking, concrete walls must be strengthened to increase structural strength. Even if the concrete of the floor is reinforced, it will not crack so easily. Therefore, there is an indissoluble bond between concrete and reinforcement, but it is not absolute. I once tried to insert a big wooden workshop in the garden and bury it underground. A few inches of concrete around the carpentry room in Fiona Fang were not reinforced, because the structural strength was not high, and there was no tension stress to worry about. So concrete is basically equal to but not necessarily equal to adding cement to the left steel root. 3) Cement = English mud = red mud? I miss you. I think you all do. Personally, people from mainland China are almost all called cement, while the vast majority of people in mainland China and Hong Kong are called Yingni. Red mud is not so popular now, and it may be out of date. 4) Is adding left steel root concrete called steel root cement? Mi, is it contradictory? In fact, it is reasonable to add steel bars and concrete as steel root concrete. I believe that it is customary to only call steel bars and cement because of accumulation. This name is believed to be popular because cement reads one word less than concrete, the strokes are simpler and easier to write, and it is also the protagonist from the perspective of chemical reaction. If the word "steel root cement" comes from the mainland, it is not surprising that there are contradictions, because the word "concrete" may not be popular in the mainland at all, so there will be no contradictions in the mainland. 5) Steel root+cement fixed steel root+concrete is used for masonry wall (housing enterprise fruit D)? The concrete wall (Housing Enterprise D) is reinforced with concrete, that is, reinforced with concrete+water+stone+sand. 6) The girl buried together is smooth and shiny = stone excrement.

Rough and dull surface = cement? Will I make an exception? Whether the concrete surface is smooth or not, I think one of the factors depends on the boards used for falling rocks. Nowadays, many construction sites use iron plates to make falling rocks, so the surface of concrete enterprises will be quite smooth. As for "rough and dull surface = cement?" In a word, I don't know what cement means in the sentence, but I believe you won't ask again after reading my answer above. As for 7) Lou Guo D is cement-fixed stone excrement? Louguo D is English mud+sand. In fact, the word "paving the way" can have different meanings. In short, if there are any requirements for tensile stress, strength and material resources, steel bar+cement mortar+stone+sand will be used. If there is no mechanical requirement, use water+stone+sand. If the mechanical and strength requirements are not high, use water and sand. 8) Floor countertops are generally cement+sand.

Yes, because the strength requirement is not high. But the floor must be steel+water+stone+sand. 9) Cement+sand = concrete? Yes, because the strength requirement is not high. 10) can you ask d more? I beg you to leave me alone! Oh, your turn! Good intentions are rewarded! There is a related answer. . knowledge. Yahoo/question/ question? Qid=7008 120500595 I am only in the field of decoration. If the content is incorrect, please ask the construction professionals to correct me. 2010-03-1121:48: 40 supplement: correction of the wrong sentence: 9) cement+sand = concrete? No, the so-called stone shit must include stone children. 2010-03-1121:53: 47 supplement: if the floor is only one or two inches or two or three inches, only cement and sand can be used, but if the thickness is more than three or four inches, stones should be added. 2010-03-1121:59: 26 supplement: in fact, the floor of the construction site with iron plates will be made of iron plates, so the concrete will be quite smooth in both the enterprise location and the ceiling surface.

D series steel root+reinforced concrete cement is darker in color.

Stone concrete is usually light gray because of Gaza. The surface of clean cement is looser than stone concrete. The countertop is generally cement+sand.

British mud cement is a raw material containing white British mud.

Ordinary English mud

... and so on are dry powder plastering, while-concrete is cement+sand+stone+water and so on.

Mix into a paste.

Solidify into a hard solid by hydration. What do you mean by stone shit? Include steel roots.

? It is mainly composed of English clay and other substances (bonded together).

1. First of all, the surface of concrete is smoother and more shiny than cement.

And a small yellow sinus.

Because concrete is hard only when it is shaken by instruments and the air is squeezed out.

So the surface of concrete will be smooth and shiny, and cement is made by hand.

Plus the cement contains no stone.

It's just mud ditch sand.

Hardness is not as good as stone shit.

Even if it is shaken by a musical instrument.

So the surface layer is rough and dull. 2. Stone concrete does not mean adding left reinforced concrete floor. Stone concrete can be used to lay a floor without steel bars.

Moreover, stone excrement has a wide range of uses. 3. In essence, it is

But in fact, red mud is just an industry term.

The correct cement is the name of the mixture of British mud and sea sand. 4. Because it is usually difficult to lift a building.

Durability and solidity can withstand gravity.

Bearing capacity and various mechanics

However, the material that can be satisfied by the current technology is the practice of adding cement to steel bars.

All descriptions of this practice are called reinforced concrete.
