Abstract
This paper reports a study on recycled aggregates concrete to analyze the influence of using two different types of natural aggregates, river aggregates and crushed aggregates, on the strength properties of recycled aggregates concrete. A total of twenty different mixes were analyzed with an effective water/cement ratio of 0.5 and cement contents of 260-300-340Â kg/m3 for recycled rates of coarse aggregates of 0-20-50-100%. The results show that the strength property depends of the type of natural aggregate used and of the recycled replacement ratio. An increment of 15% on compressive strength was obtained for river natural aggregates and 100% recycled replacement ratio, while a decrease of approximately 10-25% was observed for mixtures with crushed natural aggregates performed under similar manufacturing conditions.
