Abstract

This paper reports the results of experimental study on the effect of an amount of mortar attached to the surface of original aggregate on the physical properties of recycled aggregates such as specific gravity, and water absorption. An amount of attached mortar was evaluated by hydrochloric acid precipitation method. Test results indicated that a water absorption of recycled aggregates was proportional to the amount of mortar attached to the original aggregate.
