Experimental Dataset of the Ions in Mine Water on Mechanical Strength and Microstructure of Portland Cement

This version contains experimental data on tests with PO42.5 Portland cement mixed with mineral water containing sulfate, magnesium, and bicarbonate ions. The "Compressive Strength" section presents data on the compressive strength of cement mortar specimens (50 × 50 × 50 cm) under nine distinct experimental conditions at different curing ages (7, 28, 56, 90, and 120 days). The "XRD" section provides X-ray diffraction data of cement specimens at 28 and 90 days under five experimental conditions. The "SEM" section includes scanning electron microscopy images of cement samples at 28 days under the same five experimental conditions. The "TG-DTG" section illustrates the variations in TG and DTG values with temperature (T) for cement samples at 28 and 90 days.
