Anti-fungal mortar and concrete are developed using micro-encapsulated fungus-resisting material. D-Limonene is selected for the core anti-fungal material and Zeolite and Zeocarbon are used for reinforcing the capsule membranes. Damage and survival possibilities of microcapsules in the casting stage of mortar and concrete are examined by scanning electron microscopy (SEM) and high pressure liquid chromatography (HPLC). Several tests are conducted to evaluate the effects of microcapsule additions on the properties of fresh and hardened mortar and concrete. Anti-fungal effectiveness of the developed mortar is verified by mock-up panel tests, in which resistance to fungus growth on the panel surface is studied.
