Abstract

PURPOSE: To enable to grasp the production of crack and change, by inserting the ellipse shape rigid body at the ring center of tested ring of mortar, casting them incorporatedly and restricting the mortar with the rigid body.
CONSTITUTION: At the ring center of the mortar ring sample 1, the ellipse rigid body 3 is inserted, the contraction of mortar is restricted with the body 3 to produce cracks. By forming the rigid body as ellipse shape, the position expecting the 1st crack to the mortar ring sample 1 can be specified and the production of crack and its change can suitably be grapsed. In performing this test, the tool in combination of the base 4 providing the ellipse plate convex having rigidity on the flat plate and the ring 5 having greater inner radius than the longer radius of the ellipse convex plate, is used.
