  • 简介:参考测试方法平行地被执行,借助于化学分析,X光检查衍射,微分扫描calorimetry-thermogravimetry,扫描电子显微镜学和当面学习C4A3S的形成的极化的光显微镜和起核心作用的代理人的缺席。当tricalcium硅酸盐(C3S)显然支持C4A3S和增加desulfurization度的形成,结果与高钙和低热消费显示出那个起核心作用的代理人。在锻烧与C3S做的未加工的饭期间,没有C3S,C4A3S的谷物尺寸与那相比是更大的。并且在一样的锻烧水平,集体损失和热,消费属于CaCO3分解被减少。

  • 简介:一个批评的孔模型经常被用来由岩石计算干燥框架橡皮模量被许多因素影响的批评的孔价值。在实践,它是难的让我们获得精确的批评的孔价值,我们能通常拿经常引起错误的仅仅实验的批评的孔价值。在这份报纸,我们建议一个方法获得岩石由转换的批评的孔价值P波浪速度并且使用它预言S波浪速度。实验和日志数据的应用程序两个都证明批评的孔倒置方法能减少源于在过去使用实验的值的无常并且为预言显著地改进预言精确性的S波浪速度提供精确的批评的孔值。
