摘要
以河北段水利工程所用混凝土为研究对象,对标段所使用泵送成型混凝土试块采用回弹法进行混凝土试块强度检测研究,建立精度较高的混凝土回弹专用曲线,通过进一步的修正和完善,提出适合河北省水利工程的泵送混凝土专用回弹测强曲线公式。
Taking the concrete used in the water conservancy project of Hebei section as the research object,the strength test of the pumped molded concrete blocks used in the section was studied by means of rebound method.Based on the establishment of concrete rebound special curve with high precision,and through further modification and improvement,the formula of concrete rebound special strength curve suitable for the water conservancy project in Hebei province is put forward.
