Abstract

Aim of this project was to develop modified polymers which can reduce the precipitation of scale deposits in tunnel drainage pipes. This is necessary to reduce the maintenance costs for cleaning and flushing of the pipes. Based on this issue, 7 different compounds, consisting of a polyethylene base polymer and active fillers were developed. Selection of the fillers was based on their potential to reduce precipitations of scale deposits as well as large-scale processability. The developed compounds were processed into specimens and exposed to drainage-waters both in laboratory as well as field tests in actual tunnels. Subsequently, CaCO3 precipitations on the materials were analyzed using chemical and optical methods. Regarding the efficacy, especially the compounds with polyethylene-glycol and zeolite proved to be very promising
