Ultra High Performance Concrete (UHPC) is a new type of fiber-reinforced cement-based composite material designed based on the theory of dense packing.
Its mechanical properties are superior to traditional concrete, with compressive strength generally above 120MPa and ultimate tensile strength greater than 7MPa.
At the same time, it has good bending toughness, resistance to chloride ion penetration, corrosion resistance, and fatigue resistance.
The raw materials for preparing UHPC mainly include cement, silica fume, quartz sand, quartz powder, water, steel fibers, and high-efficiency water reducing agents, with a water cement ratio typically ranging from 0.
18 to 0.
