| 9. | This paper aims at the seriousness of concrete structure crack and presents one of main cause is that concrete early - age ( especially autogenous shrinkage ) become large through the systems academic analysis
本文正是针对混凝土结构工程早期裂缝的严重性，通过理论分析，指出目前混凝土早期收缩(主要自收缩)的变大是造成这种早期裂缝的主要原因之一。 |
| 10. | After bfs is put into high strength superplasticized expansive concrete ( substituted for cement ) , autogenous shrinkage does n ' t appear in 1 day standard curing , and e2 in 14 day ' s age is higher than that of high strength superplasticized expansive concrete without bfs in the same age
高强流态膨胀混凝土掺入磨细矿渣(等量替代水泥)后，标准养护1天未出现自收缩， 14天的限制膨胀率明显高于未掺磨细矿渣的高强流态膨胀混凝土的对应值。 |
