2021-2022 China Concrete Exhibition

2021-2022 China Concrete Exhibition focuses on the development trend and market prospect of the whole industrial chain of concrete and cement products at home and abroad, covering the upstream and downstream industries of ready-mixed concrete, high-performance concrete, precast concrete components, precast concrete piles, cement concrete pipe and box culvert, concrete admixture, lightweight aggregate concrete and eco-concrete to build a complete industrial chain. The exhibition is to hold 20+ events at the same time, inviting experts from the industry, and discussing prospective industry views in combination with current hot issues.

In order to help China's construction and this year's new infrastructure construction, China Concrete Exhibition has become a one-stop procurement and service platform for the concrete and cement products industry. At this year's China Concrete Exhibition, industry leaders, individual industry champions, etc. joined hands to make their debut. The exhibition area has been optimized, upgraded and innovated in an all-round way, which has focused on the development and changes of the industry in recent years and publicized the new technologies, new products, new equipment and transformation of scientific research achievements.

In order to help enterprises understand the latest industrial manufacturing information, new products, new technologies, new services, advanced management and operation modes of enterprises, and promote exchanges and cooperation among enterprises, local associations across China have organized local enterprises to come to Nanjing for this exhibition. During the three-day exhibition, professional insiders can be seen communicating with exhibitors in front of the booth about the latest market, inquiring suitable sources and suppliers as well as professional technical services.

In order to provide professional insiders with a good experience, this exhibition has made a bold attempt, adding some on-site interactive activities represented by“Concrete Art Floor”, showing the unique charm and superb skills of concrete art on the spot.

The 2^ndNational UHPC Design and Customization Competition

In December, 2020, the "1^stNational UHPC Design and Customization Competition" held at the same time as the exhibition shined brilliantly. The interesting, attractive competition once received wide attention from spectators. The 2^ndNational UHPC Design and Customization Competition become popular once again, with the elastic balls designed by different competitors touching the hearts of the audience every time they fell.

The theme of the second competition is "Design and Customization of UHPC Elastic Balls". The UHPC elastic balls are designed and customized according to the required size and weight, and the performances of "elasticity" and "light weight and high strength" are tested at the competition site. The competition includes three aspects: customized statement of elastic ball design, ball appearance inspection, ball compliance (physical size and weight) measurement, elastic test and damage inspection. The competition ranking is arranged according to the final score. The purpose of the competition is to investigate the UHPC material design and preparation ability, structure design ability, molding technology and team cooperation ability of the participating teams.

A total of 32 teams from UHPC materials R&D, design, manufacturing and construction enterprises, as well as professionals and students from universities and research institutes participated in this competition.
