Imitation lime stone and method for fabricating the same

The present invention relates to an artificial limestone and a method for manufacturing the same, more particularly, to an artificial limestone and a method of manufacturing the same, capable of enabling mass production of a high quality artificial lime stone by adding a silica having a particle shape, which can be seen by the naked eye, and a silica stone powder, in which SiO2 constitutes 90% of the total amount, to a cement and vacuum extrusion molding the cement; and making a surface texture like that of a limestone while obtaining a dense inner structure by using the particle-type slilica and the power-type silica stone. According to the present invention, because the vacuum extrusion molding by an extruder is used to overcome a conventional scheme of manufacturing the artificial lime stone by hand or using a mold, the high quality artificial limestone can be mass produced, which contributes to quality improvement of a construction material. In addition, a texture, quality and application of the artificial lime stone and the extruded cement are strictly distinguished in a construction site, so the production method of the artificial limestone using the extruder significantly contributes to a specialized high quality construction site.
