    摘要: PROBLEM TO BE SOLVED: To provide concrete for neutron shielding which exhibits a compressive strength equivalent to concrete using a normal aggregate, can deliver an excellent neutron shielding performance without thickening the wall of the concrete and then enables wide-ranging space designs in the construction of facilities requiring neutron shielding. SOLUTION: The concrete for neutron shielding in this invention is characterized in that it includes cement, water, coarse aggregate and fine aggregate and contains peridotite quarrying as the coarse aggregate and crushed sand of peridotite and colemanite as the fine aggregate and that the content ratio of the colemanite is 5 to 20 wt.%, referred to the total weight of the concrete.
