摘要
参照行业标准(JGJ/T23-2001)和地方标准(DB21/T834-2000),计算了实际工程长龄期混凝土的换算强度,并与芯样换算抗压强度进行了比较;提出了拓展回弹法检测长龄期混凝土抗压强度技术应用范围的建议。
The conversion strength of long-term concrete is calculated according to the industry standard（ JGJ/T 23-2001 ）and local standard （ DB21/T834-2000）,which is compared with conversion compressive strength of corresponding core.And then,the suggestion of expanding the applying range for the technology of inspection of long-term concrete compressive strength by rebound method is put forward in the paper.
