The study of shrinkage and creep in concrete, particularly in the presence of varioussupplementary cementitious materials (SCMs) and at different water to binder ratios,has shown a wide range of results in the existing literature.

Contradictory findings have been observed, and it is crucial to address thesediscrepancies. Indeed, some SCMs have been found to reduce these phenomena,while others may increase them, adding another layer of complexity to the researchlandscape.

To navigate these complexities, more comprehensive testing and data collection areimperative. A wider spectrum of experimental conditions, including different types andcombinations of SCMs and a broader range of water to binder ratios, must beexplored. This approach would help in uncovering the underlying mechanisms drivingshrinkage and creep in these complex mixtures.

Additionally, as modelling techniques have demonstrated limitations in accuratelydescribing these intricate behaviours, model refinement is needed. Modelenhancements that consider the synergistic effects of SCMs and their interactionswith the water to binder ratio can provide more accurate predictions.

Future research must delve into the intricate interplay between supplementarycementitious materials (SCMs), water to binder ratios, and time-dependentdeformations in concrete. This comprehensive investigation should encompass adiverse range of SCMs, various mix proportions, and real-world conditions.
