摘　　要：岷江龙溪口航电枢纽工程的混凝土全部使用混合砂,其质量是混凝土质量控制的重要环节。本工程混合砂的技术要求需兼顾水运和电力行业规范的要求,混合砂的质量控制目标为质量合格且品质稳定。讨论了混合砂使用中的实际问题和两个行业规范对混合砂要求的细微差异,将质量控制重点放在天然砂和人工砂的生产管理环节,提出天然砂和人工砂生产的质量控制要素,控制混合砂的品质,保证了工程的混凝土质量,实际应用效果良好。Mixed sand is completely used in the concrete of Longxikou Navigation-power Junction project in Minjiang River,and its quality is an important part of concrete quality control.The technical requirements of mixed sand in this project should take into account the requirements of water transportation and power industry specifications,and the quality control goal of mixed sand is qualified and stable quality.This paper discusses the practical problems in the use of mixed sand and the subtle differences between the two industry codes for mixed sand.The quality control of mixed sand focuses on the production management of natural sand and artificial sand,several quality control elements of natural sand and artificial sand production in this project are proposed to control the quality of mixed sand.The concrete quality of the project is guaranteed and the practical application effect is good.
