The developing nanotechnology is getting increased attention through wide range of industries. A variety of nanofibers (mostly polymer-based) can be made for applications in many research and industrial branches as well as civil engineering. One of our aims is to find out more about application of nanofibers in civil engineering. The possible uses of these electrospun nanofibers are promising as the surface protective layers. In these sense, there is a great potential for utilizing of nanofibers in civil engineering. Since the silica compounds play a fundamental role in materials applied in civil engineering, we studied the basic properties of silica-based nanofibers. We measured their biocidal properties against fungi and contact angles between SiO2 nanofibers and water. The biocidal properties of SiO2 nanofibers against fungi were evaluated by laboratory test as a percentage of the surface coverage of the fibers by fungi. Aspergillus niger was used as a model organism.Keywords: silicon oxide nanofibers, hydrophobicity, biocidal properties
