Reinforcement Corrosion: Numerical Simulation and Service Life Prediction
Abstract
Store summer bruges hvert år for at sikre holdbarheden af betonkonstruktioner, især mod armeringskorrosion. Forbedret holdbarhedgiver øget konstruktiv pålidelighed, økonomiske forbedringer i form af mindre behov for vedligeholdelse og reparation samt øget bæredygtighed på grund af en øget energi-og ressourceeffektivitet. Modellering af nedbrydningsprocesser spiller en stadig større rolle ved projektering af armerede betonkonstruktioner, og der findes i litteraturen flere modeller til forudsigelse af udviklingen af armeringskorrosion i betonkonstruktioner. Anvendeligheden af flere af disse såkaldte levetidsmodeller erdog begrænset af, at de dels er basert på antagelsen af, at betonen er fri fra revner og andre defekter, dels definerer begyndende korrosion som slutningen af levetiden og derved ikke tager højde for, at et vist korrosionomfang ikke nødvendigvis har indflydelse på den konstruktive opførsel. Formålet med det her rapporterede arbejde var at udvikle en skabelon for levetidmodellering af armeret beton udsat for chlorid-initieret armeringskorrosion og omfattende både initierings og propagerings fasen. Skabelonen omfatter koblede modeller, der beskriver transport af stoffer og korrosion af armering i revnet og urevnet beton. Skabelonen giver desuden mulighed for efterfølgende beregning af udviklingen af korrosion-inducerede mekaniske skader. Transport af stoffer i beton beregnes vha. envarme- og massetransport model, som er baseret på termodynamiske principper. Indflydelsen af temperaturen og chlorid på fugtsorption modelleres på basis af eksperimentelle resultater. Indflydelsen af chlorid er beskrevet vha. Litteratdata, mens effekten af temperaturen på fugtsorption blev bestemt vha. ”Time Domain Reflectometry” (TDR). TDR-målinger i kombination med fler-lag-adsorptionsteori gav således i vid udstrækning mulighed for at kvantificere virkningen af temperaturen på fugtsorption af cementbaserede materialer. Indflydelsen af bøjningsrevner på indtrængning af stoffer er beskrevet vha. en forenklet revnegeometri, ...
