Chemical Elements Affecting Steel Properties

Abstract: composites have many significant advantages in the application of construction engineering. For example, they can obtain high-precision complex shapes, have good resistance to degradation, and have strong corrosion resistance.

Types of building Composite Materials

1. Inorganic and organic materials

Glass fiber reinforced plastics, polymer concrete, asphalt concrete, etc.

2. Non metallic and metallic materials

Reinforced concrete, steel wire mesh cement, plastic aluminum composite pipe, aluminum foil faced linoleum, etc.

3. Other composites

Cement asbestos products, stainless steel clad steel plate, etc.

Building Composite Materials And Applications

Advantages of building Composite Materials

1. Aesthetics

They offer new aesthetic possibilities because of their ability to shape complex, smooth and creative shapes, as well as the ability to integrate special surface treatments and a wide range of effects, including the simulation of traditional materials.

2. Corrosion resistance

Composite Materials do not oxidize or corrode. There are many polymer matrix systems that provide long-term resistance in most temperature and chemical environments. Compared with traditional building materials, composite components with reasonable design have longer service life and minimum maintenance.

3. Light

Composite Materials have higher resistivity than most materials used in similar applications, which provide more gravity than most metal alloys.

4. Durability

How long can composite Materials last? There is a duration reference of more than 50 years. Polymer matrix composites are relative to the materials they usually replace, such as concrete and steel

Iron and wood are relatively new, so their “life expectancy” has not been applied in many composites.

5. Design flexibility

Composite materials can be realized in almost any shape: it may have complex structure; It may be large or small, structured, decorated, or even a combination of them. Composite materials enable architects and designers to try new concepts, from prototype to production.

In view of this flexibility, a single component of the composite materials can replace complex units that require many fixed elements, which are made of traditional materials such as wood, steel and aluminum.

6. Dimensional stability

Materials formed from FRP maintain their shape and function even under severe mechanical and environmental pressures.

7. Dielectric properties

Polymer matrix composite  materials have excellent electrical insulation properties.

8. High service temperature

Components made of polymer matrix and suitable filler have very good performance in high temperature applications.

Building Composite Materials And Applications

What are the commonly used building Composite Materials

  1.  FRP: glass fiber + synthetic resin. Its strength is comparable to that of steel, but its stiffness is not as good as that of metal. It can be used as daylighting material, enclosure material and decoration materialSuch as transparent corrugated board, translucent hollow sandwich board, daylighting cover, various composite boards, doors and windows, relief, veneer, etc. it can also make bathtubs, pipes and various containers. Basketball racks and trash cans are made of FRP.
  2.  Reinforced concrete: the concrete is not tensioned under compression, and the reinforcement can be tensioned. The thermal expansion and cold contraction coefficients of the two are close, so they are used as structural materials such as beams, plates and columns.
  3. FC cement board: there are many kinds of cement fiber board. What GRC glass fiber reinforced cement board, TK board, cement + glass fiber and other materialsMaterial. Used as ceiling, partition wall and external hanging.
4. Polymer concrete:

There are three different kinds of polymer concrete, such as polymer impregnated concrete. After the polymer infiltrates into the internal pores of the concrete, the compactness of the concrete is improved.

It can be used in special document projects requiring high strength and high durability, such as high-pressure gas transmission pipeline, high-pressure infusion pipe, high-pressure container, marine structure, atomic energy reactor and other projects.

5. Cermet, metallic glass, etc.

What are the types of checkered steel plates

 According to the process principle, pattern steel can be divided into the following common categories:

  1.  Crystal pattern steel: natural pattern steel, Uzi steel / wootz, meteorite iron (black gold), top grade rough pattern steel and top grade wrought iron.
  2.  Pouring pattern steel: it is made of pig iron and “wrought iron”, and it is made of cast steel and cast steel / wrought iron.
  3.  Rotary welded pattern steel: formed by rotary welding, rotary welded embedded steel and rotary welded horsetooth clamp steel.
  4.  Patterns produced by multi-channel steel clamping and embedded steel forging: Wolf bite blade.
  5.  Ground muscle: pattern produced by Baotou Steel earth application and blade burning technology.
  6. Knurled steel: it is formed by repeatedly folding and forging two or more kinds of steel and “iron” materials with large difference in carbon content.
  7.  Filed steel: it is obtained by filing off and forging the surface material alternately on the blade with steel. If properly controlled, this kind of sword will have better flowers Grain, sharp and elastic.
  8.  Machining Damascus like steel grain (patterned steel): Machining Damascus like steel by mechanically changing the welded steel layer or synthesizing through various procedures, mainly Foreign powder Damascus steel is the best pattern steel formed by filing (cutting) after torsion.
  9. Fusion pattern steel: the material is a variety of steels with different carbon content. Patterns can be produced by industrial fusion, welding and other processes.
