混凝土龄期是反映自身硬化程度的指标,通常直接将混凝土强度与龄期对应来实现龄期等效。鉴于传统直接法具有离散性较大和费时费力等缺点,引入电阻率法建立混凝土电阻率与龄期的对应关系,从而实现混凝土龄期等效。该方法与其他龄期等效模型比较结果表明,该等效方法是合理、可行的,且与传统方法相比,具有直接、快速、实时性等特点。研究成果可为混凝土龄期等效研究提供新思路。 Concrete age is to reflect the degree of hardening their own indicators, usually directly to the concrete strength and age corresponding to achieve age equivalent. In view of the disadvantages of the traditional direct method, such as large discreteness and time-consuming labor, the resistivity method is introduced to establish the corresponding relationship between concrete resistivity and age, so as to realize the concrete age equivalence. The comparison between this method and other age-equivalent models shows that the equivalent method is reasonable and feasible, and has the characteristics of directness, quickness and real-time compared with the traditional methods. The research results can provide new ideas for the equivalent study of concrete age.
