宁夏桥涵水泥混凝土用集料压碎值取值研究

Study on Crushing Value of Aggregates for Cement Concrete of Bridges and Culverts in Ningxia

针对宁夏桥涵水混凝土用集料,采用不同规范压碎值试验方法及不同评价标准,通过试验、分析、研究,最终提出了“桥规”新的压碎值控制标准。

In view of the different crushing value test methods and different standard evaluation of aggregates used in Ningxia bridge and culvert water concrete.In this paper,through the test,analysis and research,a new crushing value control standard of“bridge gauge”is proposed.
