洗浄回復性に優れたトンネル内装タイルの開発

抄録

Development of easy cleaning tiles for use of interior wall in tunnel was carried out. The adherent auto exhausts stains on newly developed tiles coated by silicate are found to be more easily washed out by water spraying than those on non-coated tiles. It was also found that the function of coated tiles was durable over the long term for various loads caused by the cleaning and the construction. This easy cleaning tile is expected to decrease the cost of the cleaning compared to the noncoated tiles and other conventional wall materials used in tunnel.
