摘要 根据公路工程混凝土强度试验实测资料,对使用早强型水泥的碎石混凝土7d推定28d强度的试验结果进行统计分析,探讨了影响强度增长比值的诸多因素,从建立的几种推定强度经验公式中,推荐出精度较高便于工程应用的经验公式。 On the basis of the test data of concrete strength in highway engineer-ing, statistic analysis was conducted on the test results in order to infer the macadamconcrete strength on the 28th day by its strength on the 7th day,and the elements af-fecting the strength incresing ratio were discussed also. From the exsiting empiricalequations,an empirical formula has been deduced, which is more accurate and applica-ble for the engineering practice.
