Hanhaoyang123/Pozzolanic-activity-experimental-dataset-of-calcined-coal-gangue-v1.0.2: Pozzolanic-activity-experimental-dataset-of-calcined-coal-gangue-v1.0.2

This release contains experimental data on the pozzolanic of calcined coal gangue. "The data on the strength" presents the compressive and flexural strength data of cement mortar specimens (40×40×160 cm) containing 30% calcined coal gangue at different temperatures and curing times (3 days, 7 days, and 28 days). "Column chart of strength" visually represents the flexural and compressive strength data mentioned above in the form of bar charts, with temperature intervals on the x-axis and flexural strength and compressive strength on the y-axis. "R3 activity test data" displays the weights before and after calcination, along with the weight difference representing the combined water content measured through R3 activity testing. "The bar chart of R3 activity test" visually represents the combined water content in the form of bar charts, with temperature intervals on the x-axis and combined water content on the y-axis. Thermogravimetric data show the changes in TG and DTG concerning temperature(T). FTIR curve data at different temperatures include Wavenumber and absorbance values. XRD curve data display Degrees and Intensity, along with 80 scanning electron microscope images capturing different temperature coal gangue powder photos.
