| Abstract: | This paper aims at monitoring the autogenous shrinkage (AS) of a high-performance concrete (HPC) column specimen using an embedded strain gauge just after concrete pouring. A real size specimen (40 cm x40 cra x 100 cm ) was made to simulate the structural members in construction site. The results show that the amount of HPC AS is comparable to that of drying shrinkage and even larger than it, so AS can not be omitted for HPC. By comparing the plain I-IPC and reinforce, d HPC specimens, the influences of reinforced bars on autogenous shrinkage and temperature distribution were obtained. |
