Abstract

This study aims to investigate the effect of thermal treatment on the phase formation and physical characteristics of silica asphalt composite prepared from rice husk silica and asphalt powders. The mass ratio of asphalt to silica is 1:2, and subjected to calcining temperatures of 200-450 °C. Development of structures was characterized using X-ray diffraction (XRD), Fourier Transform Infrared (FTIR) spectroscopy and scanning electron microscopy (SEM). Further evaluation was made by comparing the characteristics of the silica-asphalt composite include the density, porosity, and compressive strength. The XRD study revealed that the major phases were carbon and silica amorphous, The XRD study revealed that the major phases were silica and carbon amorphous, which were associated with are Si-OH, Si-O-Si and C-H functional groups according to FTIR analysis. In addition, an increased calcination temperatures was followed by an increase in the density and compressive strength. Based on these characteristics, the samples are considered for the roof material, suggesting their potential use in substitute lightweight steel roof devices.
