On July 26, Liu Jiaping, academician of the Chinese Academy of Engineering and director of the State Key Laboratory of High Performance Civil Engineering Materials, was invited to visit Fangqiao Company of the 14th Bureau of China Railway to give a special report on Key Technologies and Applications of Precast Concrete. Discussions and exchanges were held on strengthening school-enterprise cooperation, establishing a national high-end concrete research and development center, and promoting the transformation of research results. Academician
Liu Jiaping and his delegation first visited the company's green concrete prefabrication factory, new product test base, intelligent equipment research and development workshop, product park, etc., and learned about the product structure, production process, finished product quality and intelligent manufacturing level on the spot. Academician
Liu Jiaping said that the high intelligence and informatization applied by Fangqiao Company in the prefabrication scene of concrete products reflect the high level of on-site management ability and mature intelligent manufacturing level. He hoped that Fangqiao Company would further strengthen professional research and lead the promotion of concrete industry while maintaining the high level of automated and intelligent production. To provide guarantee for the national construction of high-quality projects.
In the special report, Academician Liu Jiaping shared his academic achievements from three aspects: research background, key technologies and applications of precast concrete, and prospects for a new generation of concrete. He pointed out that prefabricated concrete structure is an important carrier for the development of green construction, intelligent construction and lean construction, and has shown the industry trend of low-carbon, large-scale, high-quality and ultra-high performance. It is necessary to greatly improve the performance of prefabricated concrete to meet the new needs of the development of engineering assembly structure. After the
meeting, Academician Liu Jiaping and his delegation had in-depth exchanges with the leading group and R & D personnel of Fangqiao Company. He fully affirmed the preliminary work done by Fangqiao Company in concrete research, analyzed and guided the relevant work, adhered to the problem orientation, focused on solving practical problems in R & D, and timely transformed the results. Build core competitiveness. Academician
Liu Jiaping is an expert in high-performance civil engineering materials, professor and doctoral supervisor of the School of Materials Science and Engineering of Southeast University. He has been engaged in the basic theory, key technology research and engineering application of concrete crack control and high performance for a long time, and has undertaken more than 30 scientific research tasks such as major national projects. Three key technology groups, namely, shrinkage crack control, microstructure optimization and rheological property control, have been established, and major theoretical breakthroughs in concrete industry and functional materials have been achieved many times.
The development of green high-end manufacturing is the lifeline of concrete industry. At present, Fangqiao Company has done a lot of research on permeable concrete, lightweight aggregate concrete, UHPC (ultra-high performance concrete), repair mortar and so on, and has entered the stage of substantive application. At present, research is being carried out on decorative ultra-high performance concrete, foam lightweight concrete, color high-performance concrete, C80 high-strength concrete ratio, and production technology of fair-faced concrete prefabricated components. The company will take this in-depth exchange with the academician team as an opportunity to further strengthen the research of advanced materials technology and promote the high-quality development of enterprises.
