- Abstract
- The purpose of this study was to evaluate shrinkage properties and potential for shrinkage cracking of high-strength concrete containing high volume blast furnace slag (BFS). The W/B 0.34 and W/B 0.28 concrete specimens, with BFS replacement ratio for cement at 0%, 45% and 65%, were prepared to examine their autogenous shrinkage, unrestrained drying shrinkage and restrained drying shrinkage characteristics. The test results showed that the increase of BFS replacement ratio led to not only the increase of autogenous shrinkage and drying shrinkage at early curing age, but also increase of restrained stress in concrete. However, at BFS replacement ratio more than 45%, no significant effect of BFS was observed on autogenous shrinkage and drying shrinkage after 14 days. Furthermore, potential for shrinkage cracking of high strength concrete containing high-volume BFS was found to be the “low” according to ASTM C 1581/C 1581M-09a.
