【摘要】 借助实验手段对包括自收缩在内的高性能混凝土(HPC)早龄期体积变化加以精确评价是分析和控制HPC早期开裂的重要前提。本文就既有早龄期体积变化测量方法进行对比分析,旨在评述各种方法的优势、不足及可能的改良途径,从而为实验方法的选用和完善提供参考。更多还原

【Abstract】 It is the premise of analyzing and mitigating early-age cracking to precisely determine early-age volume changes of HPC by means of experimental methodology. This paper presents a state-of-the-art review on methods of measurement of earlyage volume changes. In order to provide references for choosing and updating methods of measurement of early-age volume changes, different methods reported in previous literature and proposed by authors were reviewed and compared.更多还原
