Air-hardening cementing material and method for preparing inorganic artificial stone from air-hardening cementing material

The invention discloses an air hardening cementing material and a method for preparing inorganic artificial stone by using the air hardening cementing material, aiming at solving the technical problems in the prior art that high production energy consumption and carbon emission can be generated in a white cement production process, and the prepared inorganic artificial stone product also has saltpetering. The white gamma-C2S cementing material comprises 30-50 parts of a white gamma-C2S cementing material, 0 to 10 parts of metakaolin; 0-10 parts of calcium powder; 40-60 parts of quartz sand; the mixing amount of the emulsion is 0-10% of that of the gamma-C2S cementing material; the mixing amount of the water reducing agent is 0-5% of that of the gamma-C2S cementing material; the water-binder ratio is 0.1-0.3, uniformly mixing, and pressing under the forming pressure of 3-5MPa to obtain an inorganic artificial stone product. White gamma-C2S is used for replacing white cement to serve as a cementing material of
