AGB2002/026 - Transfer of temporary corrosion protection of prestressed steel to practice by scientific and technical assistance
Overview
Background & policy context:
This project focuses on temporary corrosion protection of prestressed steel (TEKORS). Prestressed concrete is composed of high-strength concrete and high-strength steel. Because of the high strength of these two materials, the resulting structures use much less concrete and steel and are, therefore, more economical.
Objectives:
The objective of the research project is the implementation of the corrosion protection measures for pre-stressed steel into practice by means of organic protection layers. The excellent temporary effect of corrosion protection of the product Rust-Bun 310 as it was proved in laboratory tests should be transferred into practice. The priority questions here are the application as well as drying processes, which have to be optimised by the steel manufacturer using technological adjustments. In addition physical corrosion protection of anchor heads by flushing with dry air should be clarified on a suitable object.
Methodology:
Corrosion tests (climatic tests, pilot projects, Electrochemical processes), application techniques and film-drying processes.
