The mining and preparation costs of natural stone are high, and its acid and alkali resistance and pollution resistance are poor, and its functionality is lacking. At present, there are many substitutes for natural stone on the market, such as ecological stone. Ecological stone is made of recyclable materials that do not need to be mined, mainly including fly ash and slag. Compared with traditional stone, ecological stone has the advantages of environmental protection and low price, but the mechanical properties of ecological stone are poor and need to be improved.
