Modified porcelainized stoneware tiles obtained from recycling of granite and MSW incinerator fly ashes

摘要

The results for mechanical properties determined by indentation methods have been: The Vickers microhardness (H_v) values in the 6.1-6.7 Gpa range are very close to those of porcelainized stoneware. Elasticity Modulus (E) is between 106-227 Gpa, being very high the value for the C (1190 deg. C) material and ranging in the glass-ceramics products. In the case of Toughness (K_IC) for the C(1190 deg. C ) and 1A (1350 deg. C ) materials, values of 2.5 and 2.3 Mpam~1/2 have been obtained. They are higher than those corresponding to the porcelainized stoneware and similar to conventional glass ceramics [12].
