| Abstract: | In order to investigate the early-age plastic shrinkage and cracking of high performance concrete,the contrastive experiments under four different curing conditions were made by means of concrete slab testing on the concrete samples into which the self-curing superabsorbent polymer(SAP),silica fume and fly ash were added. The experimental results show that the curing environment has obvious effect on plastic shrinkage and cracking of high performance concrete,and that mineral admixtures such as silica fume and fly ash can reduce plastic shrinkage and optimize the performance of concrete. It is also found that self-curing concrete demonstrates good performance in controlling plastic shrinkage and cracking. |
