Abstract

It is indicated that the risk of early age shrinkage cracking on highstrength self-compacting concrete (SCC) increases due to autogenous shrinkage caused by low water-to-cement ratio (w/c) and high cement content. For the purpose of reducing the shrinkage strain of high-strength SCC, three kinds of shrinkage-reducing concrete materials, shrinkage-reducing admixture (SRA), blast furnace slag aggregate (BFS) and limestone aggregates were examined. It was found that these materials each showed excellent shrinkage-reducing effect better than each ordinary material when they were used separately. In addition, the authors have found that the shrinkage-reducing mechanisms were individually different and the shrinkage-reducing effect was approximately 45% to 61% when used all together.
