The pronunciation of concrete is: [tóng], usually what we call concrete, is a very common building material, widely used in various construction and civil engineering. Its history can be traced back to the ancient Roman period, but the development of modern concrete is closely linked to the technological progress and innovation of the 20th century.
In ancient Rome, it was discovered that when limestone and volcanic ash were mixed, it was possible to form a solid building material, which was the prototype of concrete. Over time, the method of making concrete gradually spread throughout Europe and was widely used in various buildings and projects.
However, the development of modern concrete is inseparable from the technological progress of the 20th century. In the 50s of the 20th century, China faced the problem of a shortage of cement, and the technical assistance of the USSR made it possible to solve this problem.
The creator of the word "concrete" is Professor Cai Fangyin, a famous civil and architectural architect. In 1953, he created this Chinese character with artificial stones, which was intended to facilitate writing and memorization in construction projects. Because the word "concrete" is simple and easy to remember, it quickly spread in the engineering community and became the standard abbreviation of concrete.
In modern buildings, concrete has a very wide range of applications. It has good compressive, tensile and shear properties, and is suitable for structural components of various buildings and civil engineering. From bridges and tunnels to high-rise buildings and water conservancy projects, concrete plays an indispensable role. At the same time, with the continuous progress of science and technology and the improvement of environmental awareness, the production methods and performance of concrete are constantly improved and optimized to meet higher engineering requirements and environmental protection standards.
As an important building material, concrete has made great contributions to the construction and civil engineering of mankind after thousands of years of development and innovation. From the concrete of ancient Rome to the concrete of modern times, it has witnessed the progress and development of human civilization.
