Overview

Randomized trial examines crack-resistance in recycled aggregate concrete, suggesting improved durability with basalt fibre reinforcement.

Key Points

  • The study aims to investigate the crack-resistance properties of recycled aggregate concrete (RAC) reinforced with basalt fibre.
  • Intervention involved varying basalt fibre volume in RAC with 100% recycled fine aggregate (RFA).
  • Mechanical properties, drying shrinkage, and crack resistance were analyzed based on BF content.
  • Grey correlation theory was used to evaluate microhardness distribution at the RFA-mortar interface.
  • At 0.2% BF, the RAC's mechanical properties improved significantly.
  • With 100% RFA and 0.25% BF, total crack area was reduced by 85.4% and maximum crack width decreased by 60.1%.
  • Crack resistance ranking was: drying shrinkage strain > flexural–compressive ratio > tensile–compressive ratio > splitting tensile strength.
