Abstract

In recent years, with the aim of lowering the environmental impact of concrete, the partial replacement of cement in concrete with fly ash (FA) and ground granulated blast furnace slag (GGBS) has received significant attention. This paper presents the first experimental study on the properties of concrete containing ternary binders with high volume Class-F FA and GGBS partially replacing cement up to 90%. A total of 15 batches of concrete were manufactured with binary and ternary binders based on FA, GGBS, and cement. Experimental tests were performed to establish the density, workability, compressive strength, elastic modulus, flexural strength, splitting tensile strength, and water absorpt..
