TX Active is a photocatalytic principle for cement products which can reduce organic and inorganic pollutants that are present in the air. TX Arca cement is specifically designed for the construction of prestigious architectural works. The aesthetic qualities of the final concrete elements, regardless of whether they are prefabricated or cast on site, are enhanced and remain in excellent condition for years. The decomposition of micro-organisms responsible for dirtying façades, the growth of which is promoted by the accumulation of fats, particulate matter and rain, ensures that surfaces remain clean and that the brilliance typical of cements in the TX range stays unchanged.
