Abstract:
Utilization of waste materials into value added products is one of the key features of current global sustainable journey. Rice husks (RH) are the major agricultural waste materials and rich source of silica. The purpose of this research is to make clay bricks by adding rice husk ash (RHA) to enhance structural properties of fired clay bricks and produce environmental friendly green building material. Further, SiO2 molecules present in the RHA can combine with Al and Fe available in the red clay to form a geopolymer to bring an additional strength to the bricks. RH was collected from local rice mills and burnt to obtained white colored ash. RHA was characterized by conducting FTIR, XRD and XRF testing to find out the composition, crystallinity and SiO2 percentage.
