  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.
