Experimental and Modeled Outputs for C-(A)-S-H Porosity Characterization of Slag-Based Cement Pastes

This dataset contains the experimental and modeling data generated in a study investigating the pore structure and intra-hydrate porosity of slag-blended cement pastes. The data were produced in the context of a research work entitled “Contribution to C-(A)-S-H porosity characterization of slag based cement pastes through a reconstitution of porous structure based on a combination of experimental and modeling approaches: influence of slag substitution rate on their porosity, morphology and pores interconnection” , which is currently under review.

The dataset includes results for Ordinary Portland Cement (OPC) pastes with 0%, 30%, 50%, and 80% blast furnace slag (BFS) substitution at a constant water-to-binder ratio of 0.5. It comprises water-accessible porosity measurements, mercury intrusion porosimetry (MIP) data, long-term water vapor sorption–desorption isotherms (up to 360 days of curing), and outputs from hydration and pore network models used to estimate capillary and intra-hydrate porosity as well as reconstructed pore size distributions.

All numerical data used to generate the figures and tables of the associated study are provided to ensure transparency, reproducibility, and future reuse for comparative analyses or model validation in cementitious materials research.
