Overview

Randomized trial investigates mechanical performance of geopolymer recycled pervious concrete with varying RCA quality, implying significance for sustainable construction.

Key Points

  • This research aims to understand how the quality of recycled coarse aggregate affects the performance of geopolymer recycled pervious concrete.
  • Prepared geopolymer recycled pervious concrete using high, medium, and low quality RCA (H-GRPC, M-GRPC, L-GRPC).
  • Systematically investigated mechanical properties, permeability, durability, and microstructural characteristics.
  • Performed tests for compressive and flexural strength, fatigue resistance, and freeze-thaw durability.
  • Initial compressive strengths for H-GRPC, M-GRPC, and L-GRPC were 79.2 MPa, 75.3 MPa, and 60.0 MPa, respectively.
  • After 100,000 fatigue cycles, compressive strength increased by 3.7%, 4.4%, and 3.0% for H-GRPC, M-GRPC, and L-GRPC, respectively.
  • Freeze-thaw durability improved with RCA quality order H-GRPC > M-GRPC > L-GRPC.
