The White Cement Behaviour with Different Materials Addition Submitted to UltraViolet Light Exposure
[EN] The building materials used as a coating on the walls are exposed at different conditions of the weather for long periods of time, reason why is very important to determine the effects of sunlight, heat, humidity and other effects of climate change in the colour and the properties of these materials. In this work was carried out a study on the behaviour of colour and gloss of white cement with some different industrial waste additions submitted to ultra-violet light exposure. The addition of the different materials employed in this work does not modify lightness or chromatic coordinates after the exposure at ultraviolet light, however reduces significantly the gloss of the samples, including white Portland cement.Peer reviewe
