Abstract
RHA has been the subject of investigation for its pozzolanic activity that heavily linked to the controlled temperature burning process in order to achieve amorphous form of silica. This paper present the characterization of RHA that was taken directly from the boiler of rice mill with uncontrolled burning temperature. Particle size analysis revealed grinding process of RHA could significantly curb the diameter size and increased specific surface area. Microstructure analysis suggest that RHA is very porous and EDX test showed the chemical content of RHA. The prospect of using uncontrolled burnt RHA as part of construction material is feasible.
