Barite concrete for proton hospital and construction method thereof

The invention relates to the technical field of proton hospital construction, and particularly discloses barite concrete for a proton hospital and a construction method of the barite concrete. The barite concrete for the proton hospital is prepared from the following raw materials in parts by weight: 198-205 parts of cement; 85 to 95 parts of fly ash; 48 to 55 parts of slag powder; 1100 to 1150 parts of steel shots; 550 to 560 parts of barite fine aggregate; 1830 to 1860 parts of barite coarse aggregate; 150 to 160 parts of water; 25-30 parts of an expanding agent; 10 to 12 parts of a water reducing agent; the construction method comprises the following steps: mixing and stirring the raw materials to obtain a concrete mixture; the concrete partition wall of the proton treatment area is subjected to segmented formwork erecting, and layered pouring is conducted through a concrete mixture; and after pouring is completed, the concrete partition wall in the proton treatment area is subjected to mold curing, regula
