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.本数据集包含一项探究矿渣复合水泥浆体孔隙结构与水化物内部孔隙率的研究所产生的实验与建模数据。该研究对应题为《基于实验与建模结合的孔隙结构重构法表征矿渣基水泥浆体C-(A)-S-H孔隙率：矿渣取代率对其孔隙率、形貌及孔隙连通性的影响》的工作，目前处于审稿阶段。 本数据集涵盖水胶比固定为0.5的条件下，高炉矿渣（blast furnace slag, BFS）取代率分别为0%、30%、50%、80%的普通硅酸盐水泥（Ordinary Portland Cement, OPC）浆体的相关测试结果。数据集包含水可及孔隙率测量数据、压汞法（mercury intrusion porosimetry, MIP）测试结果、养护时长长达360天的长期水蒸气吸脱附等温线数据，以及用于估算毛细孔隙率与水化物内部孔隙率、重构孔径分布的水化模型和孔隙网络模型的输出结果。 本数据集提供了支撑相关研究所有图表生成的全部数值数据，以保障研究的透明度、可重复性，并可供后续水泥基材料领域研究中的对比分析或模型验证工作复用。
