| Abstract |
The aim of this work was to prepare geopolymer from fly ash with loading TiO2
photocatalyst
nanomaterial. The effect of curing temperature and curing time were examined at room temperature, 60C and
90 °C and 7 day, 14 day and 28 day, respectively. The TiO2
photocatalyst nanomaterial contents was added about
0%, 5%, 10% and 15% by weight compared with only fly ash. The physical and chemical properties of mixed
power and geopolymer were characterized by many techniques such as X-ray diffractometer (XRD), UV-vis
diffuse reflectance spectroscopy (UV-DRS), N2
adsorption-desorption, Field Emission Scanning Electron
Microscope (FESEM), and compressive strength. The anatase crystalline phase of mixed powder increased with
increasing TiO2
nanomaterial contents. The energy band-gap of mixed powder was calculated by kubelka-munk
method which was about 3.2 eV. The specific surface area of geopolymer slightly increased with increasing TiO2
nanomaterial contents, while pore volume decreased with increasing TiO2
nanomaterial contents. The
compressive strength of geopolymer increased with increasing curing temperature and TiO2
nanomaterial
contents up to 10%. However, the compressive strength of the highest TiO2
nanomaterial contents showed lower
than 10% content. The compressive strength on effect of curing time at curing temperature 60C and 90 °C was
increased from 7 to 14 day, then compressive strength was decreased at 28 day except for room temperature. |
