ABSTRACT: Waste materials
of environmental risks, costly landfill disposal can be utilized in cement and
concrete applications. Partial replacement of cement in engineering projects
reduces the cost of construction with ecological benefits. The type and mix
ratio affects the strength and workability of cement-concrete matrices. This
research deals with the replacement of Class F fly ash and kaolin with cement
used in concrete. Replacement of 10% fly ash with cement improves the
comprehensive strength of concrete in 28 days period, and the workability is
increased by 53.8%. The kaolin replacement reduced both the strength and
workability of concrete.
