Abstract

In recent years, the use of fly ash (FA) and ground granulated blast furnace slag (GGBS) as cement replacement materials as well as foundry sand (FS) and recycled fine aggregate (RFA) as sand replacement materials has provided an attractive avenue toward a green construction material for decreasing the effect of concrete and construction and demolition (C&D) waste on the environment. The behavior of concrete produced with a combination of FS/RFA and FA/GGBS is presented in this paper. 17 concrete mixes were prepared, and tests were undertaken to assess workability, density, compressive, splitting tensile and flexural strength, elastic modulus and water absorption of each mix. It is shown tha..
