| Abstract Scope |
Technological characterization tests have an important influence on the evaluation of rocks, for an assertive choice of use. In this context, this work aims to evaluate the resistance that various types of natural and artificial rocks have to staining by everyday substances, through the ABNT-NBR 13818:1997 standard, annex G. During the tests, changes in the brightness of the rocks were also evaluated. After the tests, it was observed that 25% of the artificial rocks had permanent spots and in the group of natural rocks 39.29%. In general, most of the samples tested underwent some kind of change in visual appearance and final brightness. It is concluded that the artificial rocks presented greater resistance to the attack of staining agents. The group of artificial rocks presented a performance about 15% higher than that of natural rocks in terms of the presence of permanent spots. |
