Ny provningsmetodik f�r bed�mning av bindemedlets korrosionsskyddande f�rm�ga i betong. Underlag till LCA-analys och livsl�ngdsbed�mning
摘要:
The purpose of the project is to invent a new test method which will evaluate the anticorrosion efficiency from different concrete compositions and mixtures. The aim goal is that design input values for LCC-analysis and lifetime predictions will be achieved from the research results. The unreliability regarding chloride initiated corrosion of reinforced concrete when using new binding materials must be investigated in great detail to facilitate the use of new concrete binders and mixtures such as fly-ash, slag and silica fume. The technical lifetime regarding the initiation phase and propagation phase of corrosion will be evaluated in this project instead of studying the chloride threshold values. Transportation of moist and chlorides in the concrete will be evaluated in another BBT-project.
