Yufeng Group has won the first prize of Guangxi Science and Technology Progress Award for two consecutive years.

On May 30, good news came from the 2023 Guangxi Science and Technology Award Conference held in Nanning, Guangxi. Yufeng Group, a subsidiary of Beibu Gulf Port, won the first prize of Guangxi Science and Technology Progress Award for its project "Key Technologies and Applications of Industrialization of Low Calcium Corrosion Resistant Cementitious Materials for high-speed rail". This is another peak this year after Yufeng Group won this honor in 2022.

As the highest award in Guangxi's scientific and technological circles, the Guangxi Science and Technology Award is awarded to scientific and technological workers and achievements who have made great contributions to Guangxi's economy and society every year. Yufeng Group has won the highest honor in Guangxi's scientific and technological circles for two consecutive years and achieved a historic breakthrough!

"Key Technology and Application of high-speed rail Low Calcium Corrosion Resistant Cementitious Material Industrialization" is led by Yufeng Group, jointly with five units such as Wuhan University of Technology, Guilin University of Technology and Guangxi Green Cement Industry Engineering Institute Co., Ltd., through more than 10 years of dedicated research, breakthroughs have been made step by step, and finally achieved positive results.

The project has been granted 11 national invention patents, 1 software copyright and published more than 40 high-level papers, which have been appraised by China Building Materials Federation. The project has achieved a major breakthrough in key technology research and industrialization, and the overall results have reached the international advanced level.

It is reported that the results of the project have been applied in the first "Hualong 1" nuclear power plant (Fangchenggang) in Western China, the first "Linglong 1" nuclear power plant (Changjiang) in the world, and in a large number of key projects such as an airport in the South China Sea, a large port and protection base in the Beibu Gulf, and the Tengxia Water Conservancy Project in Guangxi. It has produced huge direct economic benefits and strongly supported the construction of major projects such as ocean and nuclear power.

This technology has been successfully applied

in Hainan Changjiang Nuclear Power Phase II Project. This technology has been successfully applied

in Datengxia Water Conservancy Project. Kechuang "Gene" has made great achievements in scientific and technological innovation of Yufeng Surging

Yufeng Group. Thanks to the good scientific research mechanism and cultural atmosphere of the group company, the entrepreneurial attitude of "thinking is the problem, doing is the answer", and then the long-term deposition of good science and technology genes, through years of exploration, a unique "trilogy" has been formed in scientific research.

The first song: Focus on

Yufeng Group adheres to the tenacity of "practicing to the extreme is a unique skill", relying on key projects, planting green development foundation, focusing on improving the research and development of special cement in an all-round way. Through unremitting efforts, special cement varieties such as nuclear power cement, medium heat cement, road cement, sulfate-resistant cement, masonry cement, slag cement, high iron phase cement and high corrosion-resistant cement have effectively expanded the development path of product differentiation, and have been widely recognized by the industry by virtue of their excellent quality and stability, excellent supply capacity and good after-sales service. Fangchenggang Nuclear Power Station, Changjiang Nuclear Power Station, Datengxia Water Conservancy Project, Hong Kong Airport Expansion Project and other large-scale projects and key projects use Yufeng special cement.

The second song: Innovation

Yufeng Group adheres to the concept of "innovation is the first driving force", has the courage to explore unknown areas, and has established a high level in the industry by diving into the depth of scientific and technological innovation. With the accumulation of innovative achievements and the ultimate "trick", it has brought the attraction of high-quality products and the market share of special products. It further stimulates the effectiveness and vitality of the development of circular economy and strengthens the core competitiveness.

The third song: Adhere to

Yufeng Group's long-term doctrine that "scientific and technological innovation can not be achieved overnight". The scientific and technological team has repeatedly deliberated and polished in the research field with the spirit of craftsmen. In order to provide a good environment for scientific and technological personnel, let them devote themselves to research. Yufeng Group has launched a series of training and incentive mechanisms to ensure that scientific research teams have sufficient funds, and that scientific researchers have salaries, salaries and bonuses, encouraging them to dare to sit "cold reception" and persist in "long-distance running" in one field to become the leader in this field.

Yufeng people will unswervingly implement the "five bigger" important requirements put forward by General Secretary Xi Jinping for Guangxi's development, and will make greater progress in promoting green development in the future! With our own practice, we will unswervingly follow the path guided by the leaders, hold high the banner of scientific and technological innovation, take the road of green development, and constantly devote ourselves to the research and development of key technologies such as intensive co-disposal of multi-solid wastes, intelligent manufacturing of green cement with ultra-low energy consumption and ultra-low emission, and disposal of polluted soil by cement kilns in the Beibu Gulf region, so as to promote scientific and technological innovation. To inject strong scientific and technological momentum into green development and create an intelligent green cement industry business card exclusive to Yufeng. Assistant General Manager

of Beibu Gulf Port Group Company, Secretary of the Party Committee of Yufeng Group, Chairman Yang Yi received the certificate

on behalf of Yufeng Group. Extended reading:

Key Technologies and Applications for Industrialization of high-speed rail Low Calcium Corrosion Resistant Cementitious Materials Project Innovation Highlights:

Highlight 1: First discovered the high-temperature phase separation and inactivation mechanism of iron phase in general cement. Olves the problem that the strength of the conventional common cement mainly depends on the contribution of tricalcium silicate and the strength of the cement is obviously reduced due to the increase of the iron phase content, and synergistically improves the strength and the corrosion resistance of the cement.

Highlight 2: high-speed rail key technologies for the industrialization of low-calcium cement have been developed to solve the production problems such as narrow range of clinker firing, easy balling and ring formation of high-speed rail phase clinker, reduce the calcination temperature, and reduce the use of natural resources such as coal and limestone.

Highlight 3: Industrialized production of high-speed rail low-calcium corrosion-resistant cement with the characteristics of high early strength, low hydration heat and high gelling capacity, development of major engineering application technology, and effective solution to the problem of concrete durability and easy cracking of engineering in harsh corrosive environments such as marine engineering.
