title = "Assessing Early-age Dynamic Elastic Modulus in High-Performance Concrete",
abstract = "Monitoring early-age elastic properties of concrete is critically important for accurately determining the crack risk. This paper focuses on evaluating the dynamic elastic moduli in high-performance concrete at early age. Firstly, a comprehensive set of reliable test data for dynamic elastic moduli was presented. Then, a comparative experimental investigation for assessing the static and dynamic elastic moduli values was put forward. Thirdly, the influence of curing temperature on static and dynamic elastic moduli was investigated in depth. The temperature sensitivity of static elastic moduli values seems lower than that of dynamic elastic moduli values. Importantly, the influence of sustained tensile stress on static and dynamic elastic moduli was examined. It was observed that the static elastic moduli values were more sensitive to sustained load when compared to the dynamic elastic moduli evolution at early age. Based on the newly measured test data, the possible underlying mechanisms behind such evolutions were explored.",
