Abstract
Many researches have been conducted on pozzolanic materials in Nigeria, mainly from agricultural and industrial wastes, and calcination of natural deposit material as clay. Many conclusions on these researches indicate they can improve the quality of concrete produced with them, resulting in the production of sustainable concrete. They possess the potential for more affordable construction and reduce the ill reputation concrete has garnered over the years due to its growing carbon footprint. The utilization of these wastes in concrete also reduces the pressure on landfills, an environmentally friendly process. The outcome of these researches has remained on shelves and have not been harnessed to develop a footprint for its commercial application in construction. This review seeks to address this problem. Of the agricultural wastes studied, pozzolans from rice husk, palm oil wastes can be harnessed locally for processing and local utilization in locations unique to their generation source. Wastes from coconut shells and sugar cane are not viable in their current quantity to explore commercially. The waste from corn-cob and clay processed to pozzolana in concrete applications is commercially viable to meet the Nigerian demand. However, the cement manufacturing companies in Nigeria need to adopt these wastes to produce the cheaper corresponding blended cement alongside their regular cement. The Nigerian populace needs to be educated on the benefits of utilizing these pozzolans for ease of patronage.
