1·The resistance to Na_2SO_4 attack of hardened cement paste added with asphalt was studied.

研究了掺沥青水泥石的抗硫酸钠腐蚀性能。

2·In this paper, the test method of the linear thermal expansion coefficient of hardened cement paste is studied.

本文研究了水泥石线性热膨胀系数的测试方法，并针对本试验方法制定了相关的试验制度。

3·Furthermore, the cracking layer adjacent to hardened cement paste may affect the interfacial properties oi concrete, such as bond strength.

同时，界面水泥侧的易干裂层对混凝土的界面性能(如粘结强度等)可能有一定影响。

4·The corrosion essence of the concrete is that corrosive materials attack its hardened cement paste and thus destroy the concrete as a whole.

混凝土的侵蚀实质是水泥石的侵蚀，而造成混凝土宏观破坏。

5·The results indicated that the inner self-desiccation degree of hardened cement paste containing UFA reduced more than that of ordinary hardened cement paste.

结果表明，相比于基准水泥石，UFA水泥石内部自干燥程度大大降低；

6·The expansion mechanism of hardened cement paste with double expansion sources of entringite and brucite was studied by using theory of fractal geometry and viscoelasticity.

应用分形学与粘弹性力学对含钙矾石和水镁石膨胀源的水泥硬化浆体的膨胀机理进行了研究与分析。

7·The presence of aggregates in cement-based materials might modify the pore structure of hardened cement paste, and its dilution effect and tortuosity effect could reduce chloride transport properties.

骨料改变了水泥基复合材料中浆体的孔结构，其稀释效应和曲折效应降低了氯离子的传输性能；

8·Using physical phase analysis technology, the component and shape of fly ash cement hardened paste and the offspring of HPC bearing load faction is researched.

利用物相分析技术，研究粉煤灰—水泥硬化浆体的组成、形貌以及HPC在荷载作用下的腐蚀产物。

9·However, there are large distinctions between the influences of the two types to the workability of cement paste and fresh concrete, the mechanical properties and microstructure of hardened concrete.

它们对水泥净浆和新拌混凝土的工作性的影响有所不同，此外掺加两类减水剂的硬化产物的力学性能和微观结构也具有很大差别。
