混凝土是当今世界用量最大、用途最广的工程材料之一,100多年以来,为人类建造了大量的生产、生活、交通等基础设施。然而,伴随着高层建筑、大跨度桥梁、水工大坝、地下空间的设计开发需要增强,对节能、节约资源、保护环境的日益重视, Concrete is one of the largest and most widely used engineering materials in the world today. For more than 100 years, concrete has built a large number of infrastructure facilities for mankind, such as production, living and transportation. However, with the development and design of high-rise buildings, long-span bridges, hydraulic dams and underground spaces, the design and development needs to be strengthened, and the emphasis on energy saving, resource conservation and environment protection has been increasing.
