| Abstract: |
| On the basis of the test data of concrete strength in highway engineering, statistic analysis was conducted on the test results in order to infer the macadam concrete strength on the 28th day by its strength on the 7th day,and the elements affecting the strength incresing ratio were discussed also. From the exsiting empiricale quations,an empirical formula has been deduced, which is more accurate and applicable for the engineering practice. |
| Key words: strength increasing ratio,early strength cement,macadam concrete strength inferring formula,high rate water-reducing admixture |
