Titanium dioxide photocatalysis relies at the semiconducting nature of its anatase crystal kind. building fabrics with titanium photocatalyst convey performances of air purification, self-cleaning, water purification, antibacterial motion.
This ebook describes rules of titanium dioxide photocatalysis, its functions to cementitious and noncementitious fabrics, in addition to an outline of standardization of trying out methods.

This rfile specifies specifications for oblique investigations of soil via dynamic probing as a part of geotechnical research and checking out in keeping with EN 1997-1 and EN 1997-2.
This rfile covers the decision of the resistance of soils and tender rocks in situ to the dynamic penetration
of a cone. A hammer of a given mass and given peak of fall is used to force the cone. The penetration resistance
is outlined because the variety of blows required to force the cone over an outlined distance. a continuing list is
provided with appreciate to intensity yet no samples are recovered.
Four systems are incorporated, protecting a variety of particular paintings according to blow:
- dynamic probing gentle (DPL): attempt representing the decrease finish of the mass diversity of dynamic apparatus;
- dynamic probing medium (DPM): attempt representing the medium mass diversity of dynamic gear;
- dynamic probing heavy (DPH): attempt representing the medium to very heavy mass diversity of dynamic gear;
- dynamic probing tremendous heavy (DPSH): try representing the higher finish of the mass variety of dynamic
The attempt result of this record are particularly suited to the qualitative decision of a soil profile including
direct investigations (e. g. sampling in response to prEN ISO 22475-1) or as a relative comparability of alternative in situ assessments.
They can also be used for the selection of the power and deformation houses of soils, usually of the cohesionless sort but additionally almost certainly in fine-grained soils, via acceptable correlations. the consequences is additionally used to figure out the intensity to very dense flooring layers e. g. to figure out the size of finish bearing piles, and to discover very unfastened, voided, back-filled or infilled flooring.

These techniques may vary considerably depending on the substrates, for example, tile, glass or plastics. Therefore, photocatalytic coating agents applicable to various materials are needed, and indeed are being developed. These coating agents may be divided into two categories. The first category consists of coating agents that require high-temperature heat treatment to harden the titanium dioxide films, based on the existing thin-film-forming technique. The second category consists of coating agents that make use of a low-temperature curing step made possible by the compounding of polymers and inorganic compounds.
The gross sales of Japanese photocatalyst market in 2005 were about 60 billion yen and two-third of them concerned construction materials (researched by Photocatalysis Industry Association of Japan). Photocatalyst technologies and applied products are expected to meet the demands of society, such as conserving the global environment as well as preserving the aesthetics of buildings and prolonging their lives. The need to establish unified assessment methods on functions and performance of photocatalysts becomes urgent.
Among various application fields of TiO2 photocatalysis in construction, building finishing materials with self-cleaning ability are most popular. Some prefabricated house manufacturers supplied new type of houses with photocatalyst-coated tile finishing or external finishing boards on the market a few years ago. 1 shows an overview on the present status of different international and national standards which are published or under preparation. 1. 3. Standardization of evaluation test methods for various performance of photocatalytic materials has been intensively pushed forward.
