In this study the standard samples were prepared according to CNS 1230 for the two ratios of UHPC The curing ages are 12 hr 1 day 3 days 7 days 14 days 28 days 60 days 120 days and 210 days The compressive strength of concrete cylinder specimens and the electrical impedance test of concrete surface are discussed to explore the degree of change and correlation between different ages The results of this study showed that the two kinds of UHPC UHPC 1 and UHPC 2 were found to have high resistivity and compressive strength It indicates that the concrete pore structure is very dense has excellent resistance to chloride ion penetration and the compressive strength of 28 days can exceed 100MPa The linear regression relationship between resistivity and compressive strength was R2 > 0 7 It shows that there is a good correlation between the resistance value and the compressive strength Therefore the relationship of this study can be used as a reference for the evaluation of the strength of subsequent researchers
