<p>The present invention relates to a multifunctional echo tile which is manufactured by using sludge, a product fired at the temperature of 1,050°C or more and wasted glass powder as main materials and red clay as an inorganic binder. Although the sludge and red clay are not combined with each other in past, the sodium silicate is used as a catalyst according to the present invention, so that the sludge and red clay are firmly combined with each other by the sodium silicate. The multifunctional echo tile has multi-functional characteristics such as moisture permeability, moisturization, a thermal insulation, soundproofing, pollutant filtering, representation of various colors and a gloss effect by using glaze.</p> |
