Implication

Randomized framework predicts mechanical properties of cement and geopolymer concrete, suggesting efficiency in sustainable development.

Key Points

  • The aim is to develop a mesoscopic modeling framework that accurately predicts mechanical properties of different concrete types.
  • Developed a random-aggregate RVE framework for simulating mechanical strengths of conventional and recycled concrete.
  • Conducted parametric studies on RVE size, aggregate shape, and ITZ thickness for optimal simulation results.
  • Validated the model under biaxial loading conditions.
  • Achieved uniaxial compressive and tensile strengths with a 5 cm RVE, reducing finite element numbers by 90% compared to full-scale models.
  • Successfully modeled the uniaxial compressive response of recycled aggregate geopolymer concrete.
  • Demonstrated the framework's efficiency in simulating complex multiaxial behavior.
