Pozzolanic activity experimental dataset of microwave activation coal gangue

This release contains experimental data on the pozzolanic of microwave activation coal gangue. "The data on the strength"shows the flexural and compressive strength of samples containing active CG at different insulation times and temperatures for 3, 7, and 28 days. "R3 activity test data" illustrates the weight variation of microwave activated CG mortar based on the R3 method, with an insulation time of 20 minutes.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.XRD includes photos of the microstructure of the powder samples at different temperatures.“Laser particle size” displayed the content of coal gangue powder with different particle sizes.
