Physical Properties of Waste Concrete Recycled Aggregates According to Coating Factor

Abstract:

The physical properties of waste concrete recycled aggregate according to the mixing ratio of the coating agent and the number of coatings investigated in this study. As the result, the Density of recycled aggregate increased, as the mixing ratio of the coating agent and the number of coatings increased. The percent of water absorption decreased rapidly for all coating conditions, and potential contamination test showed that among 21 items of concern, five were detected. The compressive strength of the water-permeable concrete increased by approximately 16.2% as produced with coated recycled aggregate.
