Abstract: A method for evaluating a binder includes disposing the binder on a first plate, bringing a second plate, which faces the first plate, into contact with one surface of the binder, applying a stress to the binder through the second plate, measuring a strain of the binder due to the applied stress, and calculating a curing rate of the binder based on the strain of the binder.
