Flexural Strength Testing of Topping Concrete base of Artificial Greening Layer based on Synthetic Macro Fiber Mixture Ratio

인공지반녹화 하부 누름콘크리트에 혼입되는 합성 매크로 섬유의 비율별 휨 성능 검토

For the purpose of reducing defects (cracking) in topping concretes cast as artificial greening layer base, synthetic macro fibers were mixed. The flexural strength of synthetic macro fiber mixed topping concretes was tested via comparing its performance with current topping concrete. According to the results of the testing, topping concrete with adjusted mixing ratio after mixing with 1kg of synthetic macro fiber showed approximately 15% higher flexural strength compared to the current topping concrete.
