Oat husk ashes as supplementary cementitious material

Abstract

Supplementary cementitious materials (SCMs) are recognized and utilized to minimize cement use; however, several waste sources now employed for partial cement replacement are under threat for changes in industrial production methods and local availability. As a result, alternative materials like agricultural residues are being investigated as SCMs, particularly for their pozzolanic potential as a source of amorphous silica. In this work, the pozzolanic potential of oat husk ashes is investigated.
