| 1. | Study on shrinkage of high strength lightweight aggregate concrete
高性能混凝土早期自收缩机理及诊治原理 |
| 2. | 4 . a set of equipment was designed for the shrinkage determination
设计了一种自收缩测定装置，用此装置进行自收缩测定。 |
| 3. | Study on early autogenous shrinkage of high strength lightweight aggregate concrete hslwac
高强轻集料混凝土的早期自收缩研究 |
| 4. | Study on high strength low auto - shrinkage concrete with composite aggregate - auto - shrinkage of high strength concrete with composite aggregate
高强低自收缩复合骨料混凝土的研究之二 |
| 5. | But the questions of buildings cracking of hsc are very serious . it brings people a lot of trouble and unnecessary loss
但是，其存在自收缩开裂、湿涨开裂以及脆性等缺点大大影响了高强混凝土的工作及使用性能。 |
| 6. | To the common concrete , adding fly ash or blast furnace slag can decrease the shrinkage rate , but adding silica fume deteriorate the shrinkage rate
其早期收缩主要是塑性收缩，而后是冷缩和自收缩，长期收缩以干燥收缩为主。 |
| 7. | At the primeval moulded time , cracks are mainly caused by temperature shrinkage and autogenous shrinkage , after that , it is mostly caused by dry shrinkage
混凝土浇筑初期开裂主要是温度变形和自收缩引起，后期开裂则主要是因干缩所致。 |
| 8. | The addition of calcined kaolin to cement increased the chemical shrinkage of cement stone , but it had no distinct impact on the self - shrinkage of cement stone
煅烧高岭土掺入水泥中，增加了水泥石的化学收缩，对水泥石的自收缩的影响并不明显。 |
| 9. | Moreover , the autogenous shrinkage and the possibility of cracking in the early stage of the hpc also can be controlled , with the addition of the mineral additives
掺和料的加入还可以减小混凝土早期的自收缩，减少高性能混凝土早期开裂的几率。 |
| 10. | In both models two - step regressive equations are adopted to simulate the step of quick development and the step of even change of hydration reaction and autogenous shrinkage
这2个模型均采用两阶段的经验公式，分别用于模拟水化反应和自收缩的快速发展阶段与平稳变化阶段。 |
