EXPERIMENT 2: Life After People week2

Study in Materials 

1.the cenment and concrete.

The most important material in the contemporary architecture. this material not only use in the  architecture aspect. but also is a important material for the civil aspect for example the dam, bridge or tunnel
.There are lot of type of cenment in current market it include portland cement.eneretically cement. portland cenment blends and non portland hydraylic cement
.the cenment is a material that easy to pulverization in the acid environment，such as acid rain
.the cenment is binder always use with other material such as the brick steel

The cement always use with other material such as steel or brick or stone.because the the cement is easy affected by the acid environment. 

The building after earthquake the brick , structure and cement break into small part

2.the glass

The most common material for the facade or internal wall ,As the technology improved the glas material also able to be the stairs walls but still not strong as the support material as cement or steel
.The glass is the amorphous solid material.
.The glass is have high strength but very crisp.
.The old glass will become the opaque 

                                          

3.the steel the common material for the building structure , Especially the super highrise building and large building. such as the cement the steel always use with cement to make concrete,but different between the cement and steel is steel can use without cement but cement must mix with other material.
.steel metallic material therefore it easy rust.

4.wooden

In the contemporary architecture the most structure frame already replaced by steel and concrete. But still have a lot of private house made by the wooden, expect the structure frame , wooden is also the most important material in the interior architecture.

.The wooden material always have shortcome is easy to fire.
.The wooden material have wooden texture on the surface.
.contrast with steel the wooden material is easy corrosion.
.under the oxidation the wooden material will lost original colour become the grey.                                        

5.the stone material （such as the marble）

Such as the wooden material the stone material was replaced by the concrete in the architecture structure aspect,the stone marerial have many outstanding characteritics such as high strength corrosion resistance.

.like the other natural material the most of stone material always have nice texture such as marble
.the stone material also easy to corrosion in the acid environment.
.the stone material also become the grey by the oxidation effect.
