Cement is a powdery, water hardening inorganic cementitious material that forms a slurry after being mixed with water. It can harden in air or water, and can firmly bond materials such as sand and stone together. The invention of cement can be regarded as an important milestone in the history of human architecture. Its emergence has made buildings more sturdy and durable, greatly promoting the development of human society's architecture.

In the construction industry, it is a key material for building infrastructure such as high-rise buildings, bridges, and roads. Whether it is houses, roads, or bridges, they cannot do without the support and reinforcement of cement. In addition, cement is widely used in water conservancy engineering, seaports and docks, tunnels and subways, and has made significant contributions to the country's economic development and improvement of people's livelihoods.
