Abstract
The application of photocatalysts in concrete technology is a well-established concept that carries with it the ability to give benefits to the surrounding environment. Photocatalytic cement is essentially a modified kind of cement added with photocatalytic materials that, when exposed to light radiation, can catalyse chemical reactions with water vapour and air contaminants, resulting in the degradation of these pollutants. The principal use of photocatalytic cement has been investigated for use in construction materials, particularly pavers, tiles, and concrete. The objective of these investigations is to develop surfaces that contribute to the air cleaning by breaking down pollutants. Titanium dioxide is the photocatalyst that is typically employed the most in construction materials. This is owing to titanium dioxide's higher photocatalytic activity, which is higher than that of other metal oxide photocatalysts, as well as its compatibility. In this study, microporous materials, such as Engelhard Titanium Silicalite (ETS), which are alternatives to titanium oxide as a filler, were introduced into a cement matrix, and the photocatalytic activity was analysed. Their performance was designed to be evaluated on site, with the advantage of gathering information under ambient conditions, for the purposes of exploratory or diagnostic study.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
