摘要 Fractal analysis of fracture surfaces in different kinds of refractories including magnesia-carbon and magnesia-chrome refractories was investigated.The fractal dimensions of fracture surfaces for three points bending test were determined by slit island method.The results show that the cold modulus of rupture increases with fractal dimension increasing due to the change in fracture mode depending on the bonding mechanism for a certain refractory material.
