Description	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.

Notes	This dataset contains the experimental data gathered in this assessment. The data provided herein is the original data produced by the DMA equipment TTDMA, using the controlling software Triton Laboratory, version 1.0.344, which generates, for each test performed, two output files: a ".tle" proprietary file; a ".xlsx" file containg all the data gathered and generated from the experiment.
