水泥混凝土是具有悠久历史的建筑材料之一。它所以被广泛使用是因为它具有很多优点:能够制成各种形状和尺寸的构件和结构物;同其它材料相比价格较低,原材料广泛,易于就地取材;施工、制作比较容易,不需要特别熟练的工种;抗压强度较高,耐久性、耐火性好,结构物建成后几乎不需要维修费用。因此,至今仍被各国广泛用于水工、

Cement concrete is one of the building materials with a long history. It is widely used because it has many advantages: It can be made into various shapes and sizes of components and structures; Compared with other materials, the price is low, raw materials are extensive, and it is easy to draw materials on the spot; construction, production is relatively easy, not Specially-skilled work types are required; the compressive strength is high, durability and fire resistance are good, and almost no maintenance cost is required after the structure is built. Therefore, it is still widely used by various countries in hydraulic engineering,
