Effect of Sugarcane Bagasse Ash and Ceramic Waste Dust as Partial Replacements of Portland Cement on Corrosion Behavior of HRB400 Low Carbon Steel Reinforcement in 3.5 % NaCl
Nowadays corrosion protection of reinforced concrete can be increased by improving the concretestructure, particularly the replacement of cement by mineral additives. In this study, the influence of apartial replacement of Portland cement (PC) on the corrosion behavior of HRB400 carbon steel rebar in3.5% NaCl solution was considered. The PC was replaced by a mixture of bagasse ash (BA) and ceramicwaste dust (CWD) admixtures. The mechanical results indicated an increase in compressive strengthfor BCWD concrete samples containing both BA and CWD additives. The electrochemical findingsindicated that the BCWD sample has considerably improved the structure of concrete as well asdecreased corrosion resistance due to the decrease of water permeability and chloride ion. Scanningelectron microscopy of the steel surface exhibited that the concrete structure including BA and CWDadditives was more uniform and denser compared to the PC sample which was in agreement withelectrochemical results.
