A sacrificial concrete for a core catcher and a preparation method thereof are provided. The sacrificial concrete includes raw materials in parts by weight as follows: cement, 575&#x2dc;625 parts; a quartz sand, 1200&#x2dc;1300 parts; a hematite ore, 700&#x2dc;800 parts; water, 200&#x2dc;220 parts; a water reducing agent, 7&#x2dc;10 parts; and strontium oxide, 0&#x2dc;10 parts. The process of the preparation method is simple, and the sacrificial concrete with excellent performances of fluidity, strength and high-temperature resistance can be prepared by the known mixing technology. The sacrificial concrete can reduce releasing of radioactive substancesSr andSr, so as to improve safety of nuclear power plants in case of a severe accident. Moreover, the sacrificial concrete can be used not only in a core catcher of current third generation nuclear power plant, but also in a core catcher of future fourth generation nuclear power plant, and has widespread engineering application value.
