Pollution and waste management and control are global issues, particularly in the industrial and agricultural sectors. Pollution and health dangers, particularly those linked with the cement and clay-brick industries, are concerning and demand immediate action from authorities. One method of addressing the pollution problem associated with these sectors is the possible use of some agricultural waste that has pozzolanic properties. Based on available literature, RHA is widely accessible and has a great potential as a pozzolanic material. As a result, the current study was performed to examine in depth the chemical composition of non-ground RHA collected from various rice mills in Nigeria using X-ray fluorescence (XRF) technology. The RHs were collected from four (4) separate places in Nigeria, comprising seven (7) samples. In this study, Portland limestone cement of the UNICEM brand was used as a control sample and was acquired at a cement merchant store in Nsukka, Enugu State. The husks were carefully separated from the bran before being burned in the open air. Following that, the ashes were collected and stored in a dry area of the laboratory for analysis. Chemical analysis of the ashes and cement was performed to identify the elemental composition of each ash. This study also looked at the physical characteristics of RHA and cement, such as density, specific gravity, and particle size distribution. Non-ground RHA particle size distribution findings were comparable to cement. The ashes produced by open-air burning were milky-white in color, with a percentage difference in chemical composition. These compositional differences may be due to differences in soil chemistry at the sampling sites, paddy types, and the type of chemical fertilizers used. Finally, the findings indicated that the pozzolanic properties of RHA vary based on where they are located.
