Abstract
There has been growing interest to reduce the use of conventional natural aggregates to promote sustainability in construction industry. In this study, quartz sandstones are substituted for natural igneous coarse aggregates in concrete and tested for chloride and corrosion resistance. The results indicate that the depth of chloride penetration increases with increasing quartz sandstone substitution, with similar depth of penetration to that of the control mixture observed up to approximately 20% replacement by volume. Results from corrosion potential measurements indicate no significant corrosion occurring in specimens made with either natural or coarse aggregates after 180 days of ponding.
