Strength tests: These tests are carried out to check the holding powers of various binders used in green moulding sand, dry moulding sand and core sand. These tests are performed on a U.T.M. The various test carried out includes:-
1. Compressive strength test
2. Shear strength test
3. Tensile strength test
4. Bending strength test
Out of these, compressive strength test is most important. The test specimen is
5.08 cm Φ × 5.08 cm long. The test is performed by applying a uniformly increasing load on sand specimen until it breaks. The compressive strength is read directly on the scale of the machine.
