“…A very interesting application of titanium dioxide is in the field of building materials [10]. Whether it is embedded in the bulk of concrete, mortars [11][12][13], or ceramics [14][15][16], or perhaps used as an external coating on glass and stone surface [17,18], titanium dioxide can implement these materials with photocatalytic properties. Such properties, which are effective even under weak solar irradiation [10], consist of a self-cleaning ability and an abatement of polluting molecules such as NO x , SO x , as well as BTX, with related environmental benefits.…”

“…In particular, the inclusion of or coating with specific nanoparticles for building materials has been developed in order to obtain additional and superior properties (self-cleaning, antibacterial, anti-fogging, lightness, mechanical strength, durability, fire resistance, etc.). Among these ENPs, in the construction sector, titanium dioxide is one of the most used materials to realize self-cleaning and de-polluting coatings for cement mortars, exterior tiles, paving blocks, glasses, paints, finishing coatings, road-blocks and concrete pavements [1][2][3]. Its widespread use is attributed to its main features: high catalysis efficiency, chemical stability, inexpensiveness, compatibility with traditional construction materials and cultural heritage [4].…”

Abstract:The present study concerns the ecodesign of the application of an aqueous nano-TiO2 suspension on a porous limestone used in historical monuments with a spraying system through the LCA methodology, in order to define the most critical aspects of the process and to try to minimize the environmental burden during the implementation of the application process. Because of the limited knowledge currently available regarding the effects that nano-TiO2 may have on the environment or human health, a precautionary approach has been adopted in all life cycle steps, to assess the risk of having nanoparticle emissions from a nanocoating surface and for workers, who can come into contact with or inhale the nanoparticles released. The energy-intensive operations in the application stage greatly contribute to the total environmental damage, while the impact generated by nanoparticle emissions during the use phase contributes 2.9%. In addition, the self-cleaning and de-polluting transparent titania coating produces a benefit of −0.13%.

“…For its self-cleaning behavior, TiO 2 is used in building materials and structures [12][13][14][15][16] including cement mortars, exterior tiles, paving block, glasses, paints, finishing coating and concrete pavement. Zinc oxide (ZnO) is a yellowish white powder and very soft with high specific surface area which improves the surface properties and other parameters of physical chemistry [17].…”

Many natural mines of decorative stones have been seen in the mountainous areas of the province Lorestan (Iran). Due to the traditional harvesting methods, these processes cause irreparable environmental damages. The formulation of decorative stone consists of travertine stone (TS) and marmarit stone (MS) with stone seeds 8-200 and 10-200. Cement, water, unsaturated polyester resin and fillers are used in the production of artificial stone composites from lesions of stone factory. The mechanical properties of TS with grain of size 10-200 are better than other grains and stones. The compressive strength of the samples was increased by reducing water content to 25 % and increase of unsaturated polyester resin percentage to 12 %. To improve the properties of the samples and minimization of their pores, we used fillers such as calcium carbonate, silica, silane, titanium dioxide and zinc oxide. Calcium carbonate causes softening and loss of the composite samples. The results showed that use of the fillers including micro-silica, silane and titanium dioxide increases mechanical properties and eliminated close to all pores significantly. Unlike the concrete, artificial stone composite obtained in the absence of water pool showed better properties that increase with time.
