***Description*** 
The data includes the results of the mechanical properties of the ACCs in the published article. The data can be directly used for plotting the figures in the published paper.
This research project was made possible by a grant from the European Research Council within the framework of the ERC Starting Grant Project “Auxetic Cementitious Composites by 3D printing (ACC-3D)”, Grant Agreement Number 101041342. Views and opinions expressed are however those of the author(s) only and do not necessarily reflect those of the European Union or the European Research Council. Neither the European Union nor the granting authority can be held responsible for them.

Naming convention: The naming of "RE,"RS","CR" and "MR" is kept identical to the specimens mentioned in the article.
***Test equipment***
The experiments were performed by an electric press (50 kN) UNITRONIC，a hydraulic press (10kN) INSTRON 8872 and a Micro tension-compression test machine (50N ~ 5kN).
*** Description of the data ***
The load (measured by load cell) and displacement data (measured by press stroke and LVDTs) was collected from the tests. The data was obtained from experiments and numerical simulations (ABAQUS/Explicit), then calculated using measured dimensional data (approximately 40 mm × 10mm × 40 mm from experiments) and simulated dimensions (40 mm × 40 mm with 10 mm “plain stress thickness” from the numerical model).
The columns heading is maintained the same as the figures in the published article, and the work sheet name in the "Data.xlsx" file indicates the figure number in the published paper.
