摘要
C35W12F200混凝土在长距离输水隧洞工程中应用极少,如何保障混凝土的质量对隧洞工程的使用寿命至关重要。本文提出了以C35W12F200混凝土为原材料的关键技术指标,推荐了配合比的优化措施,总结了质量控制的技术要求,改进了混凝土的投料工艺,保障了混凝土质量。
C35W12F200 concrete is applied in long-distance water transmission tunnel project rarely. How to ensure the quality of concrete has vital importance to the service life of tunnel engineering. In the paper, key technology indicators with C35W12F200 concrete as raw materials are proposed. Optimization measures of mixture ratio are recommended. Technical requirements for quality control are summarized, Concrete feeding process is improved, thereby ensuring the quality of concrete.
