Data on the UCS of Slag Geopolymer-Stabilized Soils

The dataset consists of 10 variables, including one output variable and nine input variables. The output variable is the unconfined compressive strength (UCS, MPa). The input variables comprise the water content (d₀, %), the percentages of sand (d₁), silt (d₂), and clay (d₃), the SiO₂/Al₂O₃ ratio (d₄), the contents of CaO (d₅), Fe₂O₃ (d₆), and MgO (d₇), the NaOH concentration (d₈, M), and the curing time (d₉, days). These variables were used as predictors to estimate the UCS of alkali-activated soil samples.
