Recycled aggregate quality varies, limiting its use. This study found strong correlations between RA characteristics, showing that measuring just two properties is enough to understand its quality for construction applications.

Area of Science:

  • Civil Engineering
  • Materials Science
  • Geotechnical Engineering

Background:

  • Recycled aggregate (RA) is widely used in construction but limited to lower-grade applications due to quality variations.
  • Inconsistent strength and quality of RA hinder its use in higher-grade applications.
  • Understanding RA characteristics is crucial for expanding its construction potential.

Purpose of the Study:

  • To investigate the relationships among six key characteristics of recycled aggregate.
  • To identify a minimal set of parameters sufficient for characterizing RA quality.
  • To develop predictive models for RA properties using interpolation polynomials.

Main Methods:

  • Collected RA samples from 10 demolition sites and one recycling plant.

  • Analyzed six parameters: particle size distribution, density, porosity, shape, strength, and chemical composition.
  • Employed Vandermonde matrix for interpolation and spectral methods (power spectra, bispectra) to analyze fitting errors.

    • Main Results:

    • Demonstrated strong correlations among the tested parameters of recycled aggregate.
    • Identified that measuring only two parameters (e.g., particle density and chemical content) is sufficient to characterize RA.
    • Developed best-fit interpolation equations with minimal fitting errors for property estimation.

    Conclusions:

    • The quality variations in recycled aggregate can be effectively managed by understanding inter-parameter correlations.
    • A reduced testing regime focusing on two key properties can accurately predict RA characteristics.
    • This research facilitates the broader application of recycled aggregate in higher-grade construction.
