Research about effect of fly ash content on some mechanical properties of roller compacted concrete using steel slag in road building domain in Ba Ria-Vung Tau province

Abstract

    This study presents the results to determine the effect of fly ash content on some mechanical properties of roller compacted concrete containing steel slag aggregate (BTĐLCLXT), that is utilized in road building domain in Ba Ria - Vung Tau province, consisting of Vebe stiffness, compressive strength, flexural strength, split tensile strength and elastic modulus. The results indicate that fly ash content influent significantly on workability and strength of Roller Compacted Concrete containing steel slag aggregate . The appropriate fly ash content replacing cement in Roller Compacted Concrete containing steel slag aggregate achieves probably 30%.
