Experimental Dataset on the Impact of Sulfate, Magnesium, and Bicarbonate Ions on Cement Strength under Individual and Combined Action

This dataset comprises experimental data on the effects of sulfate ions, magnesium ions, and bicarbonate ions—both individually and in combination—on the performance of Portland cement. The "Compressive Strength" section presents compressive strength data for cement mortar specimens (50 × 50 × 50 cm) subjected to nine distinct experimental conditions at varying ages (7, 28, 56, 90, and 120 days). The "XRD" section provides X-ray diffraction data for cement products at 28 and 90 days under five experimental conditions. The "SEM" section includes scanning electron microscopy images of cement products at 28 days from the same five experimental setups. The "Thermogravimetric Data" section illustrates the variations in TG and DTG as a function of temperature (T).
