Ultra-High-Performance Concrete (UHPC)
摘要
Ultra-high-performance concrete (UHPC) is a class of concrete that provides exceptionally high mechanical strength and durability due to its dense microstructure and the use of fibers, such as steel or organic fibers. UHPC’s formulation typically includes a high proportion of fine powders (cement, silica fume, quartz flour) and a low water-to-binder ratio, which results in a very low porosity. The addition of fibers enhances tensile strength and cracking resistance. This unique composition allows UHPC to exhibit superior properties, such as compressive strengths exceeding 150 MPa and significant tensile strength, making it an ideal material for demanding structural applications.
