摘要
随着天然砂资源的逐渐枯竭,机制砂代替天然砂是必然趋势,机制砂的性能对混凝土的工作性、力学性和耐久性具有一定的影响。镇江市建设工程质量检测协会在2023年度开展的机制砂实验室间比对活动,分析各实验室的检测能力水平以及识别实验室存在的问题,并对影响机制砂亚甲蓝值、石粉含量和压碎指标检测结果的因素进行了技术分析,提出相关建议。
With the gradual depletion of natural sand resources,the replacement of natural sand by machine-made sand is an inevitable trend,and the performance of machine-made sand has a certain impact on the workability,mechanics and durability of concrete.In 2023,Zhenjiang Construction Engineering Quality Inspection Association carried out the comparison of machine-made sand laboratories,analyzed the testing ability level of each laboratory and identified the problems existing in the laboratory,and carried out technical analysis on the factors affecting the detection results of machinemade sand methylene blue value,stone powder content and crushing index,and put forward relevant suggestions.
