混凝土作为一种材质，是人类历史发展长河中重要支撑的材质，也是至今为止人类历史中最富活力的胶凝材质，在全球物质使用量中排名第二，仅次于水。

混凝土，顾名思义，本质特征就是“混”与“凝”。

As a material, concrete is an important supporting material in the long history of human development. It is also the most dynamic cementitious material in human history. It ranks second in the global material consumption, second only to water.
Concrete, as its name implies, is essentially characterized by "concrete" and "coagulation".
