Abstract EN
This paper proposed a novel method to prepare porous calcium silicate hydrate (CSH) based on the calcium oxide/polyethylene glycol (CaO/PEG2000) composites as the calcium materials.
The porosity formation mechanism was revealed via X-ray diffraction (XRD), field-emission scanning electron microscopy (FESEM), Brunauer-Emmett-Teller (BET), and Fourier transformed infrared spectroscopy (FT-IR).
The reactivity of silica materials (SiO2) enhanced by increasing pH value.
Ca2+ could not sustain release from CaO/PEG2000 and reacted with SiO32− caused by silica to form CSH until the hydrothermal temperature reached to 170°C, avoiding the hardly dissolved intermediates formation efficiently.
The as-prepared CSH, due to the large specific surface areas, exhibited excellent release capability of Ca2+ and OH−.
This porous CSH has potential application in reducing the negative environmental effects of continual natural phosphate resource depletion.
