Detailed Description of the Invention

[0001]

The present invention relates to a wall material, a floor material, a roof material,
The present invention relates to a lightweight and high-strength wall material used as a building material such as and a construction method of the wall.

As is well known, various wall materials made of concrete, metal, wood, plastic and the like are widely used for floors, roofs or outer walls of buildings according to their design strength. For example, in a building made of a steel frame structure or a reinforced concrete structure, a lightweight aerated concrete (ALC) panel is used as the wall material. This ALC
The panel is made by adding a foaming agent to cement paste to make it porous, and performing autoclave curing, which is lighter than general concrete, and
Since it has a large amount of air bubbles introduced therein and has excellent heat insulation, it is widely used mainly as a floor material, a wall material, a roof material and the like.

However, the above ALC panel has the following problems. That is, the absolute dry bulk specific gravity of the ALC panel is 1.0 to 1.
It is about 5 and lighter than general concrete,
A lifting machine is required for handling during construction and it is not always easy to handle. In addition, it can support skyscrapers and skyscrapers that will be constructed in the future,
Further, it is desired to develop a material that is lightweight and has high strength.

The present invention has been made in view of the above problems, and is lightweight, easy to handle, has heat insulating property, waterproof property, and heat resistant property, and is easily strength-designed without increasing the weight so much. It is intended to provide a wall material that can be used. Further, the present invention has heat insulating properties, waterproof properties, and heat resistance,
Moreover, it is an object of the present invention to provide a wall construction method capable of extremely easily constructing a wall whose strength can be easily designed without significantly increasing the weight.
