◆ Grand opening

As a representative of the support unit of the conference, Chen Guanxiong, technical advisor of Guangdong Provincial Department of Transport and director of the Expert Committee of Guangdong Provincial Highway Society, was invited to attend the opening ceremony. He said in his speech that UHPC, as a popular new building material in China and even the world, has been applied on a large scale in the Pearl River Delta and Yangtze River Delta regions. From the first application of STC bridge pavement project in Zhaoqing Mahfang Bridge in 2011, to the largest application of the main structure of the bridge in China, to the world's largest span of the Torch 3# bridge, Guangdong Province has been at the forefront of the application of new materials and new technologies. As a practitioner in the field of transportation, he is well aware of the tremendous driving force of material change for the development of the industry, and also understands the vital importance of scientific research to support the development of the industry. The development of the industry requires the joint efforts of universities, design, construction, testing and other parties, and at the same time, it also needs a platform to promote everyone's communication. He believes that the UHPC industry Conference is the first platform in China to provide exchanges for design institutes, research institutions, industrial suppliers and construction enterprises, which has a positive promoting significance for the research and application development of UHPC. I hope that this conference will benefit all my colleagues, and I hope that practitioners in the engineering industry will take this opportunity to exchange views.

 

 

In his opening speech, Xu Yongmo, former president of China Concrete and Cement Products Association, first thanked the expert representatives for exchanging their innovative achievements at the UHPC industry Conference. He proposed and expected that although UHPC originated in Europe, it must be developed in China, which is the mission and responsibility of China's concrete materials and engineering technicians, and China should make recognized contributions to the innovation and development of concrete materials science and engineering technology. At present, the domestic high performance concrete materials provide two technical routes for the high-strength lightweight building structure: one is the high-strength lightweight aggregate concrete, which is the high-strength lightweight concrete; One is UHPC, which has ultra-high strength compressive and flexural properties, and solves the problem of excessive volume of concrete structures through ultra-high strength and lightweight. He believes that the innovative development of UHPC materials is far from over and still faces many challenges. In terms of engineering applications, China's huge construction projects provide trial and error and iteration opportunities for the innovative development of UHPC, and more "first" and "largest" UHPC engineering applications will be produced in China in the future. The development of UHPC will continue to face new problems and continue to achieve new developments, such as the innovation of engineering construction pouring technology, the application of ultra-high and ultra-large structures of wind power mixing towers of 160 meters and above, the construction of Marine cities, and ultra-large prefabricated fast-loading seawater floating structures. He believes that the conference opening today is a big review of the innovation and development of UHPC materials and engineering technology in China in recent years, and hopes that in the field of UHPC materials and engineering technology, we should follow to lead the development, and innovative brands built in China and made in China continue to emerge in the field of UHPC.

◆ "Tribute to Bach" theme activity ◆

Mr. Bach is the inventor of ultra-high performance concrete and the founder of engineering application, the academic and industrial circles do not know much about Mr. Bach's pioneering work, up to now, his theory and concept are still not out of date, and still have a good guiding role and reference value for us to broaden our vision and explore future development. With the support and assistance of Arbophor (Anqing) Co., LTD., and with the permission of the Sustainability and R&D Center of Samet Group - the unit where Bach used to work, the conference specially planned and organized the theme of "Tribute to Bach". Professor Lu Xinying of Tsinghua University and Secretary General Zhao Jun of CCPA-UHPC Branch spent a lot of time and energy. The precious technical data "Ny Beton-NY Teknologi" left by Mr. Bach was translated into Chinese "New Concrete - New Technology" as the technical data of this conference.
