The invention discloses inorganic artificial combining stone and a preparation method thereof. The artificial combining stone uses 
silicon acid-base solution to arouse 
metakaolin to react and generate 
geopolymer to serve as an inorganic cementing agent, and the artificial combining stone mainly contains the 
metakaolin, the 
silicon acid-base solution, 
natural stone aggregate, decoration aggregate, a thickening 
time control agent, inorganic 
pigment and fibers. The preparation method is firstly enabling the thickening 
time control agent and the inorganic 
pigment to be dissolved in the 
silicon acid-base solution to obtain mixed 
serous fluid, evenly blending the 
metakaolin, the 
natural stone aggregate, the decoration aggregate, the fibers and the mixed 
serous fluid, preparing the artificial combining stone through model entering or 
material distribution, vibration under the vacuum condition, molding in a pressing mode, maintaining, 
cutting, 
polishing, burnishing and surface protection. The artificial combining stone not only has decoration features which can be equal to that of resin 
artificial stone, but also is non-toxic, environment-friendly, low in cost, resisting in 
corrosion of most majority of acid-base salts, durable in high temperature and excellent in durable performance, obviously avoids whiting and saltpetering phenomena after a long time use, and is strong in 
pollution resisting capability.
