| 摘 要： | 水泥浆-集料过渡区内晶体的择优取向度对混凝土的宏观性能有很大影响。本文通过理论和实验分析指出,计算水泥浆-集料界面区内氢氧钙石的择优取向度目前所沿用的公式是不合理的。提出了用测定多晶回摆曲线并以水泥浆本体的氢氧钙石作为无规标样评定界面过渡区内氢氧钙石择优取向度的方法,并进行了相应的理论和实验研究,获得了良好的结果。

| Abstract: | The effect of preferred orientation of portlandite within interfical zone betweenaggregate and cement paste on macro properties of concrete is significant. In thispaper, it is pointed out by theoretical analyses that calculating preferrd orient-ation of portlandite within it, according to the formula continuous to use, Onlycan be used as a qualitative method. The authors proposed a method, usingrocking curve of diffraction line for measuring the preferred orientation degree ofportlandite, using that of bulk cement as a randomly standard sample. It obtainedmore precise results and can be used as a quantitative one. |
