| 摘 要： | 通过室内试验和微观试验分别研究磨细矿渣粉、膨胀剂和纤维对水泥混凝土力学性能、收缩性能以及混凝土内部结构产生的影响。研究结果表明,磨细矿渣粉与膨胀剂能够提高混凝土的致密性,防止混凝土早期开裂;纤维分散在混凝土中形成三维网络支撑体系,可增加混凝土的韧性,提高其抗裂性;此3种材料的共同使用对混凝土性能有互补作用。 |

| Abstract: | This paper investigates the influences of pulverized slag,expanding agent and fiber on mechanical properties,shrinkage properties and internal structure of cement concrete via indoor test and microscopic test,respectively.The results of investigation show that the pulverized slag and expanding agent can improve the compactness of concrete and prevent early cracking;the fiber disperses in concrete and forms a 3-dimensional network supporting system so as to increase the ductility and enhance crack resistance... |
| Keywords: | concrete crack resistance pulverized slag expanding agent fiber |
