Ultrathin high-strength composite environment-friendly inorganic artificial stone and preparation method thereof

The invention relates to the technical field of building materials, in particular to an ultrathin high-strength composite environment-friendly inorganic artificial stone and a preparation method thereof. The inorganic artificial stone provided by the invention comprises a facing layer and a structural layer, the facing layer mixture comprises 56-75 parts of cement, 8-12 parts of an auxiliary cementing material, 10-20 parts of active powder, 15-25 parts of 325 silicon powder, 70-80 parts of fine recycled concrete aggregate, 20-30 parts of coarse recycled concrete aggregate, 1-3 parts of a water reducing agent, 7-15 parts of water and 2-4 parts of a toughening agent; 15 parts of steel fibers are added to the structural layer mixture on the basis of the facing layer mixture. Different mixtures are adopted according to the characteristics of the facing layer and the structural layer, and the chopped steel fibers are added into the structural layer, so that the ultrathin high-strength composite environment-friendl
