Název v původním jazyce

Antifungal efficiency of slag based cement composites

Popis výsledku v původním jazyce

Blast furnace slag (BFS) is used for preparation of common cements, sulfate-resisting and chemical-resisting cements and cement mortars. Using BFS as a concrete or mortar addition results in several advantageous properties such as high resistance to acid attack (sulphuric, nitric acids), low chloride permeability, high durability and low capillary porosity. Because of these properties using BFS in cement composites can decrease the effect of biodegradation induced by various microorganisms. Bio-corrosion is caused by biogenic organic and mineral acids, which result from metabolic activity of microorganisms like fungi, bacteria or yeasts. In this article, the potential antifungal properties of BFS were analysed regarding the selected species of fungi (Cladosporium spp., Aspergillus niger and Penicillium glabrum). Antifungal efficiency was studied on cement composites with different share (65%, 75%, 85% and 95%) of BFS. Moderate antifungal effectivity of composites with slag was confirmed for two from three strains of studied fungi Cladosporium spp. and Aspergillus niger. (C) SGEM2018. All Rights Reserved.
