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.
