中文摘要：

混凝土内部相对湿度是决定干燥收缩的重要参数。基于新型温湿度一体数字传感器，开发埋入式混凝土内部相对湿度测量新方法，具有体积小、自动、准确、快速、高效等特点。进行C30普通混凝土和C60高性能混凝土非标准干燥收缩实验，测试干燥过程中收缩变形和内部相对湿度随龄期的发展变化，利用回归理论，建立二者的定量线性关系。

英文摘要：

Internal relative humidity in concrete is a controlling factor of dying shrinkage. A new measuring system using embedded digital sensors has been developed that provides a convenient and easy way to accurately measuring the internal relative humidity of concrete from very early age. The internal relative humidity and drying shrinkage of non-standard specimen for C30 normal concrete and C60 high performance concrete are measured at drying shrinkage condition. A linear equation between drying shrinkage and internal relative humidity of concrete are established using regression theory.
