Modulus of Rupture (psi, kg/cm 2) Modulus of rupture (MOR) is like a three-point bend test. MOR measures the bond strength of the test specimen. For castables, it measures the bonding strength of the cement matrix. The particle size and packing of the aggregate system are factors in MOR, but the maturity of the cement bond contributes more to ...
