Conventional concrete panels use lightweight aggregate as aggregate, but the specific gravity is 1.3 or higher.
The concrete weight was approximately 1500Kg/ m3 , making it heavy. Moreover, the surface finish had become rough.

In the concrete panel of the present invention, the middle layer 1 is made of concrete using lightweight aggregate 2, and the surface layer 3 has a specific gravity of 0.5 or less and passes 85% or more by weight of a 5 mm mesh sieve according to the concrete sieve standard. It is made of concrete using ultra-lightweight fine aggregate 4 as aggregate.

る。 The present invention will be described below based on embodiments shown in the accompanying drawings. 1 is the middle layer, which is made of concrete using lightweight aggregate 2 as an aggregate, and reinforced with reinforcing steel 5 or
PC steel wire is installed. As the lightweight aggregate 2, either natural aggregate or artificial aggregate can be used, and for example, foamed sludge having a specific gravity of 0.8 to 1.3 can be suitably used. This lightweight aggregate 2 has the effect of reinforcing the installed reinforcing bars 5 and the like. 3 is the surface layer, which is made of concrete using ultra-lightweight fine aggregate 4 as aggregate. The specific gravity is different from ultra-lightweight fine aggregate 4.
Aggregate with a weight of 0.5 or less that passes 85% or more by weight through a 5 mm mesh sieve, which is the standard for concrete sieves, such as perlite, styrofoam, and shirasu balloons. This ultra-lightweight fine aggregate 4 makes it possible to reduce the weight, give a smooth surface finish, and reduce internal stress, so that it does not crack even when glaze or the like is applied by baking.

In this invention, the middle layer is made of concrete made of lightweight aggregate, so it can maintain the same strength as the conventional one, and the surface layer has a specific gravity.
Concrete is made of ultra-light fine aggregate that passes through a 5mm mesh sieve, the concrete sieve standard, with a weight of 0.5 or less and more than 85% by weight, so it is even lighter without sacrificing strength. Because it is a fine aggregate, the surface finish is smooth, and the ultra-lightweight fine aggregate reduces internal stress in the surface layer, making it possible to prevent cracks from occurring when baking and painting glazes, etc. , which can be used in a wider range of applications as architectural boards.
