On April 23, the "First Beijing-Tianjin-Hebei Concrete Admixture Technology Exchange Conference" was hosted by the Beijing Concrete Association Admixture Branch and the Tianjin Building Materials Industry Association Concrete Admixture Branch with the theme of "Unity, Cooperation, Co-creation and Sharing" in Tianjin Convened.

The Beijing-Tianjin-Hebei region is also an important place in Gyeonggi, and its strategic position is very important. The total population of the Beijing-Tianjin-Hebei region exceeds 100 million people. Realizing the coordinated development of the Beijing-Tianjin-Hebei region, driving innovation, and promoting the innovation of regional development systems and mechanisms is the need for building a new capital economic circle in the future and realizing the national development strategy. Therefore, this technology The exchange meeting was held at the right time. In recent years, with the increasing application of admixtures, the influence of admixtures on concrete technology has become very significant. The level of admixture application technology is sufficient to affect the development of concrete technology in China. The two complement each other and depend on each other. At the same time, the prefabricated construction industry in my country is developing rapidly, the demand for concrete is increasing, the quality requirements are also higher and higher, the performance requirements are becoming more and more comprehensive and diversified, the demand for external additives is increasing, and the performance requirements are also increasing. It is getting higher and higher. I believe that with the rapid development of my country's concrete admixture industry and the continuous increase of construction projects, the production and application of concrete admixtures will still have great development potential and room for development.

Huang Jing pointed out in his speech that the country is currently undergoing industrial structural transformation and upgrading, and the concrete admixture industry will inevitably be affected by structural transformation and upgrading. Under this circumstance, the admixture industry can only achieve rapid development only by holding a group for warmth. He hopes that the Beijing-Tianjin-Hebei Technology Exchange Conference will become a normalized event in the future, which will promote the development of the industry while strengthening technical exchanges between industries.

Aiming at the next development of the concrete admixture industry, Zhang Feng expressed his views at the meeting. He said that since the 1970s, with the development of admixture application technology, earth-shaking changes have taken place in concrete production and construction technology, which has promoted the high-quality development of commercial concrete, and the application range of commercial concrete has become more extensive. With the continuous improvement of technical performance, admixtures have played an irreplaceable role in the improvement of concrete performance, the innovation of concrete technology and the promotion of the high-quality development of the concrete industry. He suggested that one is to strengthen technical research in combination with the current changes in sand and gravel aggregates, improve the construction performance of concrete, increase the durability of concrete, and be a good teacher and helpful friend for the development of the concrete industry. The second is to strengthen the research and development of green production technology, strengthen the exploration of the harmless solid waste application technology of recycled aggregates, and protect the green mountains and green waters of the motherland. The third is to standardize the development of the industry, expand, strengthen, and optimize the concrete admixture market to achieve healthy competition and orderly development, thereby leading the sound development of upstream and downstream industries. The fourth is to actively participate in the "One Belt One Road" initiative, to be the pioneer of international brands in the foreign additive industry, to form an international influence, to promote Chinese culture, and to sing Chinese brands. The fifth is to strengthen the coordinated development of the concrete industry and the admixture industry, and truly push my country's concrete technology and construction technology to a new level.

The conference mainly focused on the current hot issues in the industry and made thematic reports and technical exchanges. Among them, Wang Ziming, a professor of Beijing University of Technology, gave a report on the topic of "Research Progress and Development Trends in Concrete Admixtures", from the development history of polycarboxylic acid water-reducing agent macromonomers, the structural characteristics and the effects of polyether macromonomers. The impact of the polymerization process, chemical admixtures for shotcrete, summary and future pr
