The invention provides a geopolymer-based concrete material and a preparation method thereof. The geopolymer-based concrete material is prepared from a geopolymer concrete mixture, the geopolymer concrete mixture is prepared from the following raw materials: a gel raw material, quartz sand, an exciting agent raw material and a water reducing agent, wherein the exciting agent is prepared from a sodium silicate solution, sodium hydroxide and water; gel raw materials are slag and silica fume, or the gel raw materials are slag, fly ash and silica fume. The method comprises the following steps: preparing a test block from a geopolymer concrete mixture, and curing the test block in a standard curing box at 20 +/-2 DEG C for 28 days. The 28d compressive strength of the geopolymer-based concrete material can reach 130MPa or above, the residual strength after high temperature can also reach 30MPa, and the geopolymer-based concrete material also has good high temperature resistance on the premise ...
