Abstract
Influence of pore size distribution of alumina brick on its modulus of rupture (MOR) and cold crushing strength (CCS) at room temperature was studied with regression analysis method, respectively. The pore size distribution of specimens were characterized by scanning electron microscope (SEM), mercury intrusion porosimetry (MIP) , and the strength was tested by universal strength tester. The results show that the pore size distribution of alumina brick was not homogeneous, though the apparent porosity (A.P) almost no difference. The little difference of pore size distribution of specimens contributed immeasurably to dispersion of MOR, especially of CCS. At the end, analyzed the influence coefficient of each interval of pore size distribution to MOR and CCS. |
