This granite can be used for external or internal jobs due to its physical and mechanical properties. The granite samples used in this work were collected at the Transgranitos quarry located in Aguiar da Beira, north of Portugal. The main purpose of this study was to study the Branco Michaela granite characterization in relation to colour and brightness when submitted to different superficial finishing’s such as polished, honed, shot blasted, flamed, sawn. Results are presented for dry and wet samples. © 2019 The Authors. Published by Elsevier B.V.

Introduction Introduction

The study of materials properties has always been fundamental to the survival of human beings. The importance is such that we divide the great stages of our history according to the materials that predominated in our daily lives (Stone, Bronze, Copper, Iron, etc.).
