PROBLEM TO BE SOLVED: To provide a highly portable alkali-silica reaction determination apparatus capable of achieving dark and bright conditions, placing samples under the same photographing conditions, and facilitating the cleaning of the inside of a container. SOLUTION: The alkali-silica reaction determination apparatus comprises a light-shielding container comprising a lid and a container body; an imaging means oriented toward the container body when closed at a center part of the back surface of the lid; an ultraviolet lamp and a while lamp for illuminating the container body when closed at an edge part of the back surface of the lid; a low-resilience mat having water absorptivity and detachably laid on the internal bottom surface of the container body; and an operating means for making the imaging means function and selectively turning on the ultraviolet lamp or the while lamp in the outside of a determination container.
