This research investigates the improved crack and abrasion resistance in concrete with graphite tailings and basalt fibers, suggesting potential applications in road construction.
Key Points
The study aims to evaluate the impact of graphite tailings and basalt fibers on the early-stage crack resistance and abrasion resistance of concrete.
Tested mechanical properties of modified concrete with added graphite tailings and basalt fibers.
Evaluated early plastic cracking and abrasion rates compared to ordinary concrete.
Conducted microscopic tests to analyze cement hydration and gel formation.
Graphite tailings and basalt fibers reduced early plastic cracks and increased mechanical strength.
Concrete with 20% graphite tailings showed a 32.8% reduction in abrasion rate.
Concrete with 20% graphite tailings and 0.1% basalt fibers had a 50.8% reduction in abrasion rate.
C-S-H gel content and chain length increased by 5.4% and 12.5%, respectively, with 20% graphite tailings.
