【摘要】：为测试某水电站坝址人工骨料的云母类型及其相对含量,采用X射线衍射(XRD)定量法对坝址开挖材料中5种千枚岩和3种片麻岩进行分析测试。结果表明,X射线衍射定量法可以准确测试人工骨料中云母类型及相对含量,千枚岩中白云母的相对含量为18%~42%,片麻岩中白云母的相对含量为21%~26%。且XRD方法测试的云母含量为岩石总云母含量,不同于《水工混凝土砂石骨料试验规程》规定的细骨料中游离云母含量概念,因而不宜采用《水工混凝土施工规范》中规定的云母含量限值进行限制。
[Abstract]:In order to test the mica type and relative content of artificial aggregate at the dam site of a hydropower station, five kinds of phyllite and three kinds of gneiss in the excavation material of the dam site were analyzed and tested by X-ray diffraction (XRD) quantitative method. The results show that the type and relative content of mica in artificial aggregate can be accurately measured by X-ray diffraction quantitative method. The relative content of Muscovite in kilomite is 18% 鈮，
