"precast concrete"的定义和意义

What is "precast concrete"?

Precast concrete is a type of concrete that is made in a controlled environment, like a factory, and then transported to a construction site for use. It is shaped and hardened into specific forms, such as walls, beams, or slabs, before being delivered. This method ensures consistent quality, saves time during construction, and allows for greater precision compared to pouring concrete on-site. Precast concrete is commonly used in buildings, bridges, and other structures where strength and durability are important.
