Flexible fillers has recently been implemented as corrosion protection for post-tensioning
tendons used in bridge structures in Florida. There are two different explanations why
corrosion could take place: 1. water is able to reach the steel 2. Microbiologica l ly
Influenced Corrosion.
The aim of this research is to evaluate corrosion protection effectiveness of five differe nt
microcrystalline waxes under different environmental conditions. Specimens tested ranged
from 7-wire steel strands to single wires (12-16 cm). Another aim is the appraisal of wax
degradation by fungi species. Single wires coated with each of the investigated protection
materials, were sprayed with suspensions of three different fungi species and a mix of them.
For single wires, independent of the environmental condition the specimen with more
corrosion was Nontribos, as well as the filler coated wires contaminated with Fungi. Fungi
species investigated were able to utilize the waxes as carbon source and caused differe nt
extents of MIC. / Includes bibliography. / Thesis (M.S.)--Florida Atlantic University, 2017. / FAU Electronic Theses and Dissertations Collection
