| Abstract |
The purpose of this study is to analyze steel corrosion properties of the concrete containing wasted tile powder. The specimens were made with wasted tile powder as various replacement ratio(10, 15, 20%) for average particle size 5㎛, 10㎛, plain concrete and concrete containing fly ash, blast-furnace slag(10, 20%). A few properties, such as, compressive strength, chloride migration coefficient, steel corrosion area ratio, steel weight reduction ratio, half cell potential and SEM were tested. From the test results, wasted tile powder replacement ratio up to 15% decreased chloride migration coefficient, but wasted tile powder replacement ratio 20% concrete was a tendency to increase drastically. The steel corrosion area ratio, steel weight reduction ratio of concrete containing mineral admixture was lower than plain concrete. Wasted tile powder replacement ratio 10, 15% concrete which average particle size 5㎛ indicates better performance than blast-furnace slag replacement ratio 20%. |
