摘要
实验研究了混凝土干缩及自收缩性能。结果表明,高性能混凝土具有严重的自收缩现象。但整体的干缩与普通混凝土相似。掺入硅灰将增大高性能混凝土的自收缩。
The drying shrinkage and self shrinkage of concrete wer e experimentally studied. The test results show that the high performance concre te (HPC) behaves as significant self shrinkage due to the consumption of water caused by the cement hydration. However the drying shrinkage of HPC is similar to that of the normal strength concrete. The incorporation of silica fume increa ses the self shrinkage of HPC.
