Long-Term Sulfate Resistance of Blended Cement Concrete with Waste Glass Powder
https://orcid.org/0000-0001-9881-7497
This study aimed to evaluate the long-term sulfate resistance of green concrete with blended cement at different waste glass powder contents. The used cement was blended with 10%, 20%, 40%, and 60% of waste glass powder. To benchmark performance, the X-ray diffraction (XRD) test was used to estimate the pozzolanic effect of glass powder, which exhibits a calcium hydroxide decrease. The concrete natural aggregates were replaced by 50%, and 100% with glass at 60% glass powder replacement. There was a direct relation between the concrete diffusion coefficient and the waste glass powder in blended cement. Results of compressive strength loss show a high sulfate resistance with waste glass powder content increasing in cement. Concrete with 50% glass aggregates produced a comparable enhancement in sulfate resistance to that produced with natural aggregates.
