摘要
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。
The age of concrete is an important index for analyzing its strength development.The equivalent age is usually realized based on the corresponding strength of concrete with age.Since the direct method has disadvantages of large discreteness,time-consuming and energy-consuming,resistivity is introduced to establish the relationship between concrete resistivity and age so as to realize concrete age equivalent.Compared with other age equivalent models,the results show that the proposed method is feasible and reasonable.Comparison of the traditional methods,the proposed method has direct,rapid and real-time characteristics.The experimental method can provide new ideas for study of concrete age equivalent.
