Abstract

The study conducted a thermal conductivity test of magnesium oxide to manufacture boards using absorbent to produce board of radon gas molecules that are absorbed into the indoor air pollutants, which are currently in question, among other indoor air pollutants. Using material are the vermiculite and anthracite, in case of the vermiculite, which results in large porosity due to the expansion, in case of the anthracite, which characteristic generates pore on the matrix. As a result of the experiment, the lowest value was given to 0.6161 kcal/mh℃ which adding vermiculite 10% and anthracite 40%. However, adding vermiculite 40% and anthracite 10%, slightly higher 0.7229 kcal/mh℃, it is deemed the anthracite has more porosity than the vermiculite and, it judged that pore occurrence during the mixing process, appeared that the heat conductivity go down.
