Resumo
As propriedades físicas e mecânicas definem os materiais e o estudo da variação da cor e do brilho, consoante o acabamento final dado ao granito Branco Micaela, é de suma importância, já que permite potenciar novas utilidades para este recurso, para que se possa transformar em vários produtos e consequentemente abranger vários mercados. Assim, foram recolhidas amostras do granito Branco Micaela, que por sua vez foram sujeitas a diferentes acabamentos: polido, amaciado, serrado, flamejado e granalhado. As amostras depois de lhes ser conferido o acabamento respetivo, foram alvo caracterização relativamente a sua cor e brilho. Verificou-se, assim, como variam estes fatores, não só no material a seco como também quando sujeito ao contacto com a água. Este trabalho permitiu verificar a existência de variações na cor e no brilho mediante o tipo de acabamento e quantificar o efeito da água nestes parâmetros levando a novas abordagens comerciais do granito “Branco Micaela” pois quantifica o grau de cor e de brilho de vários tipos de acabamentos que podem ser utilizados consoante as aplicações e características desejadas.
The physical and mechanical properties define the materials and the study of the of the variation of colour and gloss, according to a given finishing treatment applied to the Branco Micaela granite is of great importance, so that new utilities can be glimpsed for this resource and it can be transformed in several products and consequently cover several markets. Branco Micaela granite samples were collected, which in turn were subjected to different finishes: polished, honed, sawed, flamed and shotblasted. Branco Micaela granite samples, after being given the respective finishing, were examined according to their colour and brightness and it was verified how these factors vary with the finishes, in dry and wet conditions. This work allowed to verify the existence of variations on the colour and brightness through the finishing and to verify the effect of water in these parameters allowing new commercial approaches of "Branco Micaela" granite because it was quantified the degree of colour and brightness obtained using several finishes.
