Mortar's design from shell powders associated with LDH nanocomposite Ti - Zn -type

Abstract : The active photo-catalytic TiO2 has been widely applied in the science of building materials because of its ability to remove pollutants from surface of buildings. This approach can be beneficial for the design of building materials to reduce environmental impact. Actually, new inorganic nanocomposites based layered double hydroxides (LDH) associated with TiO2 are introduced to increase the compatibility of the photocatalyst with the mortar. In this paper, we introduce other nanocomposites LDH associated with zinc, as additions to the Portland cement mortars; the aim is to study the physico-chemical properties of the elaborated mortars. The permeability and mechanical properties of mixtures based on mineral powders of small particle size of shell powders associated with LDH nanocomposites type Ti-Zn are tested. Measurements of apparent density, porosity to water and permeability, mechanical properties and Scanning Electron Microscopy were performed. The results show that these properties are similar to those of standardized mortars.
