茄子山水库面板堆石坝面板混凝土配合比试验的基本思路是在满足设计要求的前提下 ,本着就地取材、经济合理原则 ,为快速滑模施工提供脱模后不下坍、不开裂、凝结时间合适的优质混凝土。由于当地仅有的花岗岩机制砂云母含量超标达 7% ,为降低云母含量 ,提出了与龙陵灰岩人工砂按 1∶1混合使用的配合比 ,对此通过对比试验研究了云母含量对混凝土性能的影响。实践证明 :混凝土现场抽检与试验结果一致 ,各项指标均达到要求 ,表明混凝土中云母含量少量超标不会对质量有太大的影响 Eggplant Hill Reservoir Faced Rockfill dam concrete mix panel test the basic idea is to meet the design requirements of the premise, in line with the local materials, economic and reasonable principles for the rapid sliding mode of construction to provide demoulding after collapsing, no cracking, condensation Good quality concrete at the right time. Because only the local granite mechanism sand mica content exceeded 7%, in order to reduce the mica content, put forward the Longling limestone artificial sand mixed by 1: 1, through the comparative study of the mica content of concrete The impact of performance. Practice has proved that: spot sampling of concrete is consistent with the test results, and all the indexes meet the requirements, indicating that a small amount of excessive content of mica in concrete will not have too much influence on the quality
