Replication Data for: Influence of stress and specimen geometry on three-point bending DMA in hardened cement pastes

Understanding the viscoelastic behaviour of cementitious materials presents experimental challenges, particularly in studying short-term mechanisms and minimizing size-dependent effects. While Dynamic Mechanical Analysis (DMA) can help address these limitations, its application in cementitious materials has been essentially as a ready-to-use tool for qualitative studies, with a lack of understanding regarding its methodological aspects. In hardened cementitious materials, DMA is most effectively performed using three-point bending, making the test dependent on several parameters, including static stress level and dynamic stress amplitude. Characterizing the effects of these parameters, along with specimen geometry, is essential for enabling the quantitative use of DMA data and enhancing the understanding of viscoelasticity in cementitious materials. This work investigated how static and dynamic stresses, and specimen geometry, affected the measurements of storage modulus and loss tangent obtained from three-point bending DMA tests in hardened cement pastes.
