The utility model discloses a forming device for
expansive cement expansion rate test, which belongs to the technical field of
expansion rate test, and comprises a base, a pair of detachable end plates are arranged on the base, a plurality of mutually parallel partition plates are arranged between the pair of end plates, small holes are respectively arranged in the areas of the end plates between the adjacent partition plates, and the small holes are communicated with the end plates. A
small hole is formed in the end plate and used for being connected with a nail head, a limiting protrusion is arranged in the
small hole, a limiting groove matched with the limiting protrusion is formed in the nail head, and the end plate is detachable in the limiting direction of the limiting protrusion. According to the forming device for the
expansive cement expansion rate test, a limiting protrusion is arranged in a
small hole, a limiting groove matched with the limiting protrusion is formed in a nail head, an end plate is detachable in the limiting direction of the limiting protrusion, the limiting protrusion is inserted into the limiting groove, and therefore the nail head can be limited; the nail head is prevented from rotating or moving in the small hole, so that the nail head is prevented from falling off or inclining from the small hole when the test body vibrates.
