| 1. | Research on experiment and expansion model of expansive concrete filled steel tube
钢管微膨胀混凝土试验与研究 |
| 2. | Soundness , as a vital quality index of weakly expansive concrete added with magnesia , attracts much attention of dam constructers
安定性是外掺氧化镁微膨胀混凝土的一项重要的质量指标，引起了大坝建设者的高度重视甚至担忧。 |
| 3. | 3 . it is in favor of evaluating soundness of wecam by means of combining concrete autoclave expansion with its strength
3 .把混凝土的变形与混凝土的力学性能结合在一起考虑，更有利于周全评估外掺氧化镁微膨胀混凝土的安定性能。 |
| 4. | So e2 of the concrete will decrease . this research reveals a basic viewpoint : the strength development should coordinate with expansion increase . this still can be applied
不同膨胀剂的性能存在差异， csa膨胀混凝土的负温强度与膨胀率均优于同条件下的cea膨胀混凝土，也优于复掺csa和队的混凝土。 |
| 5. | Bfs can reduce the early strength of high strength superplasticized expansive concrete and make expansion effect develop fully . so high strength concrete with bfs shows higher e2
磨细矿渣的加入使高强膨胀混凝土的早期强度降低，膨胀效应得以较充分发挥，所以加入磨细矿渣的高强混凝土显示出较高的膨胀率。 |
| 6. | The evaluating standard for soundness of added with magnesia , which is based on the standard for cement paste at present and criticized by many experts of dam construction , have to be improved
目前，外掺氧化镁微膨胀混凝土的安定性评定标准绝大多数沿用的是水泥净浆标准，许多专家对其提出异议，有待改进。 |
| 7. | Because construction and curing quality is more important to anti - cracking performance of hsc and fatal to the compensating - shrinkage concrete than anything else , we should pay attention to them
针对剪力墙等重要工程结构易开裂问题，配制了纤维增强微膨胀混凝土，并对其工作性能、体积稳定性以及力学性能进行了研究。 |
| 8. | In this dissertation the author puts forward the concept of high performance expansive concrete ( hpec ) , and deems that hpec is a compound material of ec ( expansive concrete ) and hpc in which both sides can bring well play
本文提出了高性能膨胀混凝土( hpec )概念，认为hpec是ec (膨胀混凝土)和hpc发挥各自优势的有机结合。 |
| 9. | 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。 |
| 10. | The expansion and strength of middle strength superplasticized expansive concrete develop more coordinately . fa reduces the early strength of middle strength superplasticized expansive concrete , and this make more expansion become invalid when the concrete is in plastic state
中强流态膨胀混凝土的膨胀与强度性能发展比较协调，粉煤灰的加入降低了早期强度，使更多的膨胀变为无效膨胀消耗在仍处于塑性状态的混凝土中，混凝土限制膨胀率减小。 |
