Thermal analysis and microstructure of Portland cement-fly ash-silica fume pastes
Thermal analysis (thermogravimetry and differential thermal analysis) was used with scanning electron microscopy technique to investigate the hydration mechanisms and the microstructure of Portland cement-Fly ashsilica fume mixes.
