초록

The environment-friendly building material, photocatalyst/scoria/loess concrete, was prepared using scoria and loess (which have merits as building materials) and photocatalyst (which has the functions to compose the environmental contaminants and of self cleaning). In order to apply this material as a building material, the compressive and flexible strengths, and water absorptivity (which have been set by Korea Industrial Standard) were measured. In order to know the environment-friendly characteristics of this material, several tests, such as, the tests of emissivity and emission power of far infrared ray and acoustic absorptivity, antibacterial test for Escherichia coli and Pseudomonas aeruginosa, antifungal test for mixed fungal strains, and deodorization test of ammonia were carried out. Moreover, the removal characteristics of NOx, and formaldehyde (HCHO) by photocatalyst/scoria/loess concrete were examined as the following different parameters: the removal characteristics of these contaminants with the substitution ratio and the kind of photocatalyst, light source, UV intensity of sunlight, relative humidity, intial NOx concentration.
