Abstract
Disclosed is a method of manufacturing an artificial stone, and the method includes forming an artificial-stone paste which comprises 20-20 parts by weight of silica stone, metakaolim or silica fume, 200-300 parts by weight of quartz chips, 30-36 parts by weight if water, 1.5-3 part by weight of water-reducing agent and 0.2-3 parts by weight of pigment with response to 100 parts by weight of white cement; injecting the artificial-stone paste in a mold; primarily vacuum-molding the artificial-stone paste injected in the mold; secondarily vibration-molding the primarily molded artificial-stone paste; primarily curing the secondarily molded artificial-stone paste; secondarily curing the primarily cured artificial-stone paste, which induces a hydrothermal reaction and thus causes a pozzolanic reaction; releasing the secondarily cured artificial-stone paste from the mold; and surface-machining the released artificial-stone paste.
