Abstract

• This paper reports the results of physical and chemical characterization of bamboo based biochar. The bamboo was washed with fresh water to remove impurities such as dust. Bamboo was dried in room temperature. The bamboo ash was obtained in electric furnace at 1000 C for 3 h and 6 h respectively. Structural properties of bamboo ash were examined by X-ray diffraction (XRD). Scanning electron microscope (SEM) was used to observe the morphology of bamboo ash. Chemical characterization was carried out by X-ray fluorescence (EDXRF) and vibrational characterizations of bamboo ash was studied by FTIR spectroscopy. Each bamboo ash was used to form biochar ceramics by different amount of silica gel, PVA and DIW. These biochar ceramics were annealed at 200 C for 1 h to be binder burnt out. They were annealed at 600 C for 1 h to be more rigid. Physical properties such as firing shrinkage, bulk density, biochar yield, pH value of bamboo ash solution, moisture content, specific gravity and hydration capacity of Bio-char ceramics were determined.
