굴패각 분말을 혼입한 모르타르의 은입자 도포에 의한 기능성 평가

Abstract

The several functions of manufactured the gypsum incorporating oyster shell powder coated by submicro-silver solution and carrried out the tests for the adsorption of formaldehyde and antibiotic actions. Several environmentally- friendly architectural materials, clay and flyash were tested for the comparison of the adsorption efficiency. The mortar by solidified and dried was exposed in the small chamber for the 180min with 4000 μg/m3 of the initial concentration of formaldehyde and observed high removal efficiency which result was not any difference in adsorption performance of other tested materials. The microbial flora analysis of oyster mortar coated by submicro-silver solution and the similarity test were performed and observed that the densities of Aeromonas sp. Enterococcus sp., and Micrococcus sp. were decreased and the densities of Staphylococcus sp., Escherichia sp., Bacillus sp., were taphylococcus sp, Escherichia sp., and Bacillus sp. were increased.
