Abstract

Aggregate as the main constituent of concrete (about 60 to 70% by volume) highly affects both fresh and hardened concrete properties. Thus to minimize concrete cost and improve its quality it is necessary to achieve optimum aggregate gradation. Coarseness Factor chart is one of the recent popular methods for achieving an optimum aggregate gradation, which represents the relationship between Coarseness Factor and Workability Factor of a mix. This paper utilizes several trial mix data to explore the relationship of Coarseness Factor and Workability Factor with different fresh and hardened concrete properties.
