This paper reports the composition and properties of highly flowable selfconsolidating concrete (SCC) mixtures made of high proportions of cement replacement materials such as fly ash and pulverized limestone instead of high dosage of a plasticizing agent or viscosity-modifying chemical admixtures. Self-consolidating concrete mixtures 2 are being increasingly used for the construction of highly reinforced complex concrete elements and for massive concrete structures such as dams and thick foundation. In this study, by varying the proportion of portland cement, fly ash, and limestone powder, SCC mixtures with different strength values were produced, and the properties of both fresh and hardened concrete were determined. Sustainability criterion was assessed based on the life-cycle assessment (LCA) approach, which is particularly crucial for a methodical analysis and quantification of the overall environmental impacts of concrete production.This study quantifies the reduction in global warming potential based on a LCA of highvolume fly ash concrete.
