The deck of the Mihara Bridge, composed of bendable concrete, is only five centimeters thick and has an expected lifetime of one-hundred years. [ 2 ] Though HPFRCCs have been tested extensively in the lab and been employed in a few commercial building projects, further long-term research and real-world application is needed to prove the true ...
A fiber-reinforced composite (FRC) is a composite building material that consists of three components: [1] [2] the fibers as the discontinuous or dispersed phase, the matrix as the continuous phase, and; the fine interphase region, also known as the interface.
Recent studies on high-performance fiber-reinforced concrete in a bridge deck found that adding fibers provided residual strength and controlled cracking. [29] There were fewer and narrower cracks in the FRC even though the FRC had more shrinkage than the control. Residual strength is directly proportional to the fiber content.
The steel-reinforced road bed contains nearly 800 m3 of ECC material. The tensile ductility and tight crack control behavior of ECC led to a 40% reduction in material used during construction. Similarly, a 225-mm thick ECC bridge deck on interstate 94 in Michigan was completed in 2005.
The traditional decking material is pressure-treated wood. The current material many contractors choose to use is composite decking. This material is typically made from wood–plastic composite or fiberglass reinforced plastic (FRP). Such materials do not warp, crack, or split and are as versatile as traditional pressure treated wood.
Micro-reinforced ultra-high-performance concrete is the next generation of UHPC. In addition to high compressive strength, durability and abrasion resistance of UHPC, micro-reinforced UHPC is characterized by extreme ductility, energy absorption and resistance to chemicals, water and temperature.
