Abstract
Recycled aggregate (RA) has been used in various construction applications around the world, mainly as sub-grade, roadwork and unbound materials, but not in high-grade applications. This paper examines relationships among demolished concrete (DC) characteristics, properties of their RA and strength of their recycled aggregate concrete (RAC). A Vandermonde matrix for interpolation polynomials coefficient estimation is used to give detailed mathematical relationships among pairs of samples, which can be used to determine redundant tests. Different orders of interpolation polynomials are used for comparison, hence the best-fit equations with the lowest fitting errors from different orders of polynomials can be found.
