Prevention and prospect of water-soluble hexavalent chromium in cement

As a traditional building material, cement has been used in China for over a hundred years.

The cement industry, as an important raw material for the main economic construction and development in China, poses great harm to human health and the environment due to the content of water-soluble chromium family in its related products.

However, hexavalent chromium toxicity ranks first and most representative among other chromium compounds.

Among the chromium family, hexavalent chromium is the most toxic, so it is urgent to change the concept of development before governance.

The heavy metal hazards caused by the development of the manufacturing industry are particularly severe, generally caused by factors such as unqualified heavy metal products manufactured in mining, casting, and small workshops.

However, the accompanying toxicity control issues still require technological progress.

Therefore, it is urgent to study and prevent the source of water-soluble hexavalent chromium.

The TechnicalColumn technology column focuses on professional focus and focuses on Cheng Hongjian.

At present, most cement raw materials are utilized as waste, which saves costs.

At present, the reduction and elimination of water-soluble hexavalent chromium in cement products is urgent, and prevention and control technologies at various sources have attracted the attention of scholars.

Currently, almost all cement in China contains water-soluble hexavalent chromium.

The main source of toxicity is water-soluble chromium, and among the water-soluble chromium family, water-soluble hexavalent chromium has the strongest toxicity.

China’s economy, science, and civilization are constantly developing at a high speed, from the previous development before governance to the current development while prevention.

It can easily penetrate the cell membrane and has a strong oxidizing effect, which is closely related to our daily life.

It can continue to damage the respiratory tract, digestive tract, skin, and mucous membranes of the human body, and over time, can cause cancer
.

Not only does water-soluble hexavalent chromium have toxicity, but all chromium compounds have toxicity.

With the demand for high-quality development, not only does it require continuous improvement in performance, but it also faces stricter requirements in terms of green, safety, and environmental protection.

The Current Situation of the Domestic Industry and Cement Toxicity 1.1 The Transformation of the Development Road of Cement in the Domestic Industry.

Environmental protection issues are increasingly attracting the attention of China’s environmental protection departments.

Hexavalent chromium can enter the body through contact with the respiratory tract, esophagus, and skin.

A review is made on the sources and toxicity prevention measures of water-soluble hexavalent chromium in cement in the domestic industry, and further prospects are given for the future development trend of cement.

The author, Huang Hongxing, is from Fujian Provincial Product Quality Inspection and Research Institute.

1.2 Transformation of the development path of cement in the domestic industry.

While the industry is making progress in development, it will also face more severe environmental problems.
