Concrete durability dataset (SWAT, water/chloride penetration) under mix design and curing variations (n = 250)

This dataset contains experimental measurements for evaluating concrete resistance to water and chloride ingress under systematically varied mix designs and curing regimes. It includes 250 records derived from 25 concrete mixtures, each tested with 10 specimens cured under five curing conditions (two specimens per curing condition). The binder system covers ordinary Portland cement (OPC) and high-alite cement (HAC), with supplementary cementitious materials including ground granulated blast-furnace slag (GGBFS) and fly ash (FA), as well as combined FA+GGBFS in selected mixtures. Coarse aggregate type includes andesite and limestone, and chemical admixtures include air-entraining agent (AE) and superplasticizer (SP).
The dataset provides 12 input variables describing mixture proportions, aggregate type/content, admixture dosage, and curing components, and five durability-related outputs: SWAT at 2 min, SWAT at 10 min, liquid water penetration depth, chloride penetration depth, and an initial absorption index (Si). The dataset supports regression modeling, sensitivity analysis, and reproducible benchmarking for durability-oriented concrete design under chloride-rich exposure conditions.

本数据集收录了用于评估混凝土在系统调控的配合比设计与养护制度下抗水及氯离子侵入性能的实验测量数据。本数据集共包含源自25组混凝土配合比的250条实验记录：每组配合比制备10个试样，分别在5种养护条件下养护，每种养护条件对应2个试样。胶凝体系涵盖普通硅酸盐水泥（ordinary Portland cement, OPC）与高阿利特水泥（high-alite cement, HAC），辅助胶凝材料包括粒化高炉矿渣粉（ground granulated blast-furnace slag, GGBFS）、粉煤灰（fly ash, FA），部分配合比中复掺了FA与GGBFS。粗骨料类型包含安山岩与石灰岩，化学外加剂涵盖引气剂（air-entraining agent, AE）与高效减水剂（superplasticizer, SP）。
本数据集包含12项输入变量，涉及配合比参数、骨料类型与含量、外加剂掺量以及养护相关参数；同时包含5项耐久性相关输出指标：2 min时的SWAT、10 min时的SWAT、液态水渗透深度、氯离子渗透深度以及初始吸水指数（Si）。本数据集可用于面向富氯离子暴露环境下耐久性导向的混凝土配合比设计的回归建模、敏感性分析以及可复现的基准测试。
