摘要
对百色工程采用辉绿岩人工骨料特性 ,巴马克制砂石粉含量高 ,级配不连续 ,中间级配缺乏 ,通过在辉绿岩人工砂中掺部分河砂技术方案 ,降低了石粉含量 ,调整了砂级配 。
The artificial diabase aggregate used for Baise multipurpose dam project has high silt percentage from the Bamac granulator, discontinuous grading and is short of intermediate grading. By mixing the artificial diabase sand with fluvial sand, rock silt percentage is reduced and sand grading adjusted. Test and study is conducted for the property of RCC of artificial sand mixed with fluvial sand.
