《一小时推定混凝土强度新技术》于1982年通过鉴定。1983年国家计委给我们下达了此项新技术应用研究的课题。早在1982年鉴定会上,就有人提出准确性的问题。这些年来,我们一直环绕这一问题进行试验研究,不断总结这方面的经验。实践证明,一小时快速测强(即促凝压蒸法推定混凝土强度)的准确 The “one-hour presumed concrete strength new technology” passed the appraisal in 1982. In 1983, the State Development Planning Commission gave us the subject of this new technology application research. As early as the 1982 appraisal meeting, some people asked questions about accuracy. Over the past years, we have been conducting trials and studies around this issue and continuously summing up our experience in this area. Practice has proved that one-hour rapid strength measurement (ie, accelerating pressure steaming method to determine concrete strength) is accurate
