Studies on the biological contaminants (bacteria and fungi etc.) that affect the health of residents have attracted little interest compared to chemical toxicity substances such as volatile organic compounds (VOCs) and formaldehyde emitted from interior materials, in spite of the increasing number of cases of residents’ poor health and damage to interior materials due to fungi, bacteria, and insects. Only a few investigations on the biological contaminants of building materials have been performed. In this study, the antifungal effects of phytogenic natural antifungal substances extracted from Marjoram, Phytoncide, Thyme, Ginkgo leaves, and Artemisia princeps were investigated on five types of mold. Using phytogenic natural antifungal substances selected for the basic experiment, antifungal non-cement mortars were made, and their durability in addition to the antifungal performance of the non-cement mortars were also investigated. The results clearly showed that the antifungal non-cement mortars with the marjoram extract had excellent antifungal performance and long-term antifungal effects compared with other antifungal non- cement mortars. It was also shown that the optimum addition rate of marjoram extract in the non-cement mortar was 5% by mass of binder, considering the long-term antifungal effect and the antifungal performance.
