Eco-Friendly and Thermal Conductivity Properties of Magnesium oxide Matrix Utilizing Bentonite

벤토나이트를 활용한 산화마그네슘 경화체의 친환경성 및 열저항 특성

This study that prevent cancer using absorbent to inflow Radon gas in the room existing soil and rock is making board to absorb the Radon gas as a fundamental study. So, we use bentonite as a absorbent. So, we use bentonite as a absorbent. Bentonite is a 'clay mineral' composed to montmorillonite of main component that volcanic ash denatured to a clay mineral. Bentonite has fine microparticle of nano level, abundant mineral 66 of kinds, adsorbability, swelling, a positive ion(heavy metal adsorption reaction) as a bentonite's property. Using magnesia cement for oxide of magnesiuma and magnesium chloride as a main binder, we measure Radon gas absorbent efficiency and thermal conductivity.
