Effect of tropical climate condition to compressive strength and microstructure properties of High Performance Fiber Reinforced Concrete (HPFRC)

Additional of fiber in concrete creates fiber reinforced concrete (FRC) with an improvement of the mechanical properties of the concrete. However, fiber incorporation in FRC is limited to 2% to allow normal mixing procedure. To address this issue, high performance fiber reinforced concrete (HPFRC) i...
