The invention discloses a rare-earth cement column and a preparation method thereof. The rare-earth cement column comprises cement, stones, sand, rare-earth metal nitrate, rare-earth metal oxide, polypropylene, plant fibers, formaldehyde, alkali, water and a water reducing agent. The preparation method comprises the following steps: (1) mixing the cement, the stones, the sand, the rare-earth metal nitrate, the rare-earth metal oxide, the polypropylene, the plant fibers, the formaldehyde, the alkali, the water and the water reducing agent to obtain concrete; (2) pouring the concrete into a reinforcing steel bar skeleton, and then curing to obtain the rare-earth cement column. The rare-earth cement column prepared by virtue of the method has excellent high temperature resistance and high compressive strength.
