Quality properties of Recycled fine Aggregate according to method of Trituration

The production of recycling aggregate is used to process in the crushing that recycling aggregate isn't perfect the concrete aggregate in Korea. This study is examine to the properties of recycling aggregate used method of trituration. Test item is the fineness, density and percent of absorptance, solid volume percentage of aggregate. The result is that first, the method of trituration is excellent to increase the time of trituration and steel ball but decrease washing water. Second, method of trituration is improve to the properties of recycling aggregate but aggregate of production is irregularity. And method of trituration have to study of the many test items.
