When did cement exist in the history of China?

In the history of China, cement production began at 1906.

1889, near Kaiping coal mine in Tangshan, Hebei, China, Tangshan "fine cotton soil" factory produced by shaft kiln was established.

1906 Qixin lime company was established on the basis of this factory, with an annual output of 40,000 tons of cement.

1952, China formulated the first national unified standard, and determined that cement production should be based on the principle of multi-variety and multi-label. According to its main mineral composition, Portland cement was renamed Portland cement, and later renamed Portland cement, which is still in use today.

In 20 12, the cement output in China reached 265,438+84 million tons, accounting for more than 50% of the global output.

Extended data:

After more than one hundred years' development, the output of China cement industry accounts for more than 50% of the world, ranking first in the world.

As early as the Yangshao culture period in the Neolithic Age BC, our ancestors knew how to draw caves with "white gypsum" and then learned to build adobe walls with yellow mud. By the 7th century BC, lime began to appear.

During the Southern and Northern Dynasties in the 5th century A.D., a building material named "Three Muds" appeared. However, due to the stagnation of social economy, the development of building cementitious materials in China seems to stop at the stage of "three soils".

The development of China cement industry in different periods was related to the political events at home and abroad at that time.

In the late Qing Dynasty, the Opium War opened the door for China to close its doors to the outside world. World powers invaded China, imported goods, set up factories and plundered them, including importing cement and setting up cement factories in China.

In the Westernization Movement in the late Qing Dynasty, a large amount of cement was needed for the construction of military industry and civil industry, which promoted the rise of national cement industry in China.

After the Russo-Japanese War in the early 20th century, Japanese cement capital entered China with the invasion of the Japanese invading army, and started a number of Japanese cement enterprises.

During the First World War, the world powers were so keen on the civil war that they had no time to take care of the further plunder of China, so the national cement industry in China developed by leaps and bounds.

During the War of Resistance against Japanese Aggression period, the national industries in the occupied areas suffered setbacks and destruction. Due to the needs of war and economic construction, some small cement plants were produced in the southwest, central and northwest areas behind enemy lines.

After the founding of People's Republic of China (PRC), a large number of cement enterprises were built in the planned economy period, and modern cement enterprises in China were born one after another because of the reform and opening up.
