Abstract

To address the shortfalls of existing varieties of ultra rapid-hardening cement, which is becoming more popular for resurfacing bridge deck overlays, we evaluated the effects of adding metakaoline and a latex polymer to such concrete. The modified cement showed excellent durability, based on its permeability characteristics and resistance to abrasion, repeated freezing and thawing, and scaling, and may prove an effective long-term solution for resurfacing bridge deck overlays.
