| Abstract: | 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. |
| Keywords: | strength increasing ratio early strength cement macadam concrete strength inferring formula high rate water-reducing admixture |
