| 摘 要： | 针对在河砂中掺入一定比例的机制砂可以改善混凝土工作性能进行了试验分析，试验结果表明：当混凝土工作性能不能满足要求时，可掺入一定比例的机制砂以改善混凝土的工作性能．且其力学性能也能满足相关技术规范要求，并成功地运用到云南龙陵一瑞丽高速公路第6合同段桥梁工程中的重要结构部位．在满足质量要求的同时也产生了一定的经济效益。

| Abstract: | In the light of the mechanism sand in the river mixed with a certain proportion of sand can improve the workability of concrete, the paper does a experiment, the experimental results show that when the concrete performance can＇t meet the requirements, it can be mixed with a certain percentage of the mechanism sand to improve its working performance, and its mechanical properties can meet rel- evant specification requirements, and successfully applied in important structural parts of No.6 contract section of bridge engineering of Longling-Ruili Expressway in Yunnan Province, which can meet the quality requirements and produce a certain economic benefits. |
