Recently, much researches have been made to use recycled aggregates that are produced from waste concretes; the recycled aggregates may be used instead of the natural aggregates. As the amount of construction waste, most of which is waste concrete, increases steeply every year, large-scale recycling of recycled aggregates will solve the aggregate shortage as well as cutting the cost and environmental damages incurred in the process of burying the wastes. However, the recycled aggregates have the disadvantages of inferior properties which must be solved in order to reuse recycled aggregates. Hence this research aims to contribute to the alternative use of recycled aggregate by improving the physical characteristics through surface treatment: the type of surface treatment solution, its concentration, impregnation time, drying method and drying time will be varied and the physical characteristics of recycled aggregates will be compared accordingly in order to deduce the most efficient method of surface treatment.
