Abstract: The article deals with testing and evaluating the mould resistance of carbide lime by-product from deposits in comparison with the effect of reference conventional slaked lime. The mould resistance of limes was tested on a mixture of mould such as Gliocladium virens, Paecilomyces variotii, Penicillium funiculosum, Chaetomium globosum, and Aspergillus niger as well as evaluated according to the method stated in the technical standard STN 724310: 1993. The evaluating scale for mould resistance is from 0 up to 5 in the fungal growth degree (FGD). The FGD value 0 stands for no fungal growth comes about and construction materials and products have the microbiostatic effect against filamentous fungi. The experiments confirm the microbiostatic effect against mould of carbide lime by-product from deposits as well as reference conventional slaked lime; however, the microbicidal effect against mould has not been confirmed at all; the inhibiting area—zone—did not form on the agar growth media around the tested samples. Application of carbide lime by-product from deposits ensures increased mould resistance of construction materials with the microbiostatic effect against mould in accordance with technical standard STN 724310: 1993.
