| Laboratory accelerated and outdoor exposure durability test results were compared using concrete specimens made with supplementary cementitious materials (SCMs). Although testing conditions were substantially different, both sets of results indicated that mixing SCMs impaired the resistance of concrete to carbonation but improved the resistance to chloride ingress. The carbonation depths measured in the specimens exposed to outdoor conditions were lower than those estimated by the accelerated carbonation test that employed severe testing conditions. Additionally, significant gaps in the chloride profiles were found between the specimens exposed to outdoor conditions and those immersed in salt water. The chloride profiles of the exposed specimens containing high volume SCMs were affected by carbonation of surface concrete. |
