Abstract

This study investigated the corrosion resistance of concrete with recycled concrete as coarse aggregates using impressed voltage test (IVT). Recycled concrete aggregates (RCA) are aggregates produced by crushing materials made of concrete such as construction and demolition waste. Impressed voltage test is a method that accelerates the corrosion process of steel in a short period of time by applying uniform voltage among the specimens. Five different RCA replacements were considered in this study, namely: 0, 25, 50, 75 and 100 percent by volume. The water-to-cement ratio and curing days were constant at 0.50 and 28 days, respectively, using Type I Portland cement. Results showed that through qualitative analysis , the level of corrosion current curve of concrete with RCA is higher than the control. Quantitative analysis of data through estimation of the degree of corrosion intensity in concrete. Furthermore, the maximum current and time to initiate first crack of concrete also increase with the presence of RCA.
