The prediction of compressive strength for recycled coarse aggregate concrete in cold region
Case Studies in Construction Materials, 2023 Concrete in cold environments may suffer from frost damage, which effects the hydration reaction and early strength development of cement. This study aims to test the early strength development of recycled coarse aggregate concrete in cold region using ...

Properties of self-compacting high-strength concrete containing multiple use of recycled aggregate
Journal of King Saud University: Engineering Sciences, 2020 Advances in recycling can exceed traditional practice in that a non-renewable resource can at least become a partially renewable resource. This research attempts to support the cradle-to-cradle concept by testing the effect of reused recycled concrete ...
