| 摘 要： | 与同强度等级的普通混凝土对比,通过试验研究了低强度自密实混凝土收缩特点以及膨胀剂对自密实混凝土的收缩和抗压强度的影响.研究结果表明:低强度自密实混凝土收缩值高于同强度等级的普通混凝土;随着膨胀剂掺量的增加,自密实混凝土收缩值在降低,而其抗压强度先增加后降低,存在峰值.并对其机理进行了初步探讨.

| Abstract: | Compared with the same intensity level of ordinary concrete,the characteristics of shrinkage of low-intensity self-compacting concrete are analyzed,and the impact on shrinkage and compressive strength of self-compacting concrete caused by the expansive agent are studied.The value of shrinkage of low-intensity self-compacting concrete is higher than the same intensity level of ordinary concrete,the value of shrinkage of self-compacting concrete drops as the content of expansive agent increases,and its compre... |
