In the present invention, as a means for constructing a multifunctional artificial marble composition and a multifunctional artificial marble which reproduces the color of the natural color of natural marble or natural stone and has various functions as a construction finish material, ", And a multifunctional artificial marble composition composed mainly of" expanded vermiculite "prepared by selective calcination of vermiculite and" mica flakes "showing a scaly shape and a pearly glossy glass luster, a method for producing the same, and a multifunctional It features artificial marble. These multifunctional functions include sound absorbing the sound frequencies incident on the surface and the inner surface by forming a breathable three-dimensional structure or a breathable layered structure on the inner surface and the surface, and forming a continuous cell structure having a heat insulating structure to provide a humidity control anti- , And a multifunctional artificial marble having a function as a lightweight built-in finishing material. |
