预应力混凝土, 预压应力混凝土
a strong and durable construction material created by introducing internal stresses through tensioned steel tendons within the concrete
Pre-stressed concrete is a type of concrete that is specially treated to make it stronger and more durable. Before the concrete is poured, steel tendons or wires are stretched and placed inside the form. Once the concrete hardens, the tendons are released, putting the concrete under compression. This process helps the concrete resist bending and cracking under heavy loads. Pre-stressed concrete is commonly used in building bridges, parking structures, and large buildings where high strength and durability are required.
- The bridge was built using pre-stressed concrete to ensure it could withstand heavy traffic loads.
这座桥是使用预应力混凝土建造的，以确保它能够承受沉重的交通负荷。
- The team carefully monitored the tensioning of the steel wires in the pre-stressed concrete to ensure proper performance.
团队仔细监测了预应力混凝土中钢线的张拉情况，以确保性能适当。
- The architect recommended pre-stressed concrete for the high-rise building's foundation to handle the weight of the structure.
建筑师推荐使用预应力混凝土作为高层建筑的地基，以承受结构的重量。
- Pre-stressed concrete is often used for large spans in bridges because it can carry more weight without bending.
预应力混凝土常用于桥梁的大跨度结构，因为它可以在不弯曲的情况下承受更多重量。
