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. Calcium silicate hydrate (C-S-H), ettringite, gehlenite hydrate (C2AS...
