| Abstract: | It has been recognized that there exists a serious need for recovery and reuse of industrial wastes. Agglomeration by pelletization method can alleviate the problems associated with fly ash. The objective of this study was to evaluate the material properties of manufactured aggregates produced from fly ash and cement mixing by pelletization method. Engineering properties of the manufactured aggregates were evaluated experimentally. Crushing strength, specific gravity, water absorption, particle size distribution, surface characteristics and shear strength properties of the manufactured aggregates were evaluated. For all practical purposes, the study showed that the manufactured aggregates are a good alternative for wide range civil engineering applications. |
