A method for manufacturing artificial marble boards and sculptures is provided to produce the harmless boards and sculptures having excellent strength and tensile strength, and to save a production cost without using a large-size pressing apparatus. A method for manufacturing an artificial marble board includes the steps of: mixing 100 parts by weight of alumina cement(Al2O3CA-50), 180-250 parts by weight of natural stone powder, 10-50 parts by weight of wollastonite(CaSiO3), 2-10 parts by weight of gypsum(CaSO4), 1-10 parts by weight of a self-waterproof agent(Na2O nSiO2 xH2O), 0.01-0.1 parts by weight of a hardening acceleration solidifying agent(Li2CO3), and 40-60 parts by weight of water to prepare a first mixture; pouring the first mixture into a mold to perform vacuum compression molding; and polishing the vacuum-compression molded board. Further, the method for manufacturing the artificial marble board additionally includes a step of mixing one or more selected from TAO2, FeO3, Fe2O4 and Na6Ai4Si6S4O30 with the first mixture.
