Property Differences of Recycled Concrete Aggregates With the Euclidian Distance

To quantize the property differences between construction recycled concrete aggregates(RCA) and pavement RCA,the quantitative analysis with Euclidian distance indicating the diversity of two sequences was carried on,based on the data of property trials that include apparent density,water absorption,crushing index value,etc.The Euclidian distance of single properties and variance of entire property for construction RCA were all greater than that of pavement RCA.Therefore,pavement RCA comes closer to the natural aggregates than construction RCA.Additionally,the entire property of pavement RCA is more stable than construction RCA.As a result,pavement RCA favors the application in project of higher requirements.
