From July 13 to 15, 2021, the 6th "Subert Cup" National Concrete Material Design Competition for College Students was held in Wuhan University of Technology under the guidance of the Material Teaching Steering Committee of Colleges and Universities of the Ministry of Education. 144 teams of college students from 80 universities in the fields of materials, civil engineering and transportation participated in the competition. After fierce competition in theory examination, mix ratio design and field practice, two teams of Chongqing University won the special prize for team and the first prize for team, respectively, creating another great achievement for Chongqing University.
The National Concrete Material Design Contest for College students, sponsored by the Education and Human Resources Committee of Chinese Association of Concrete and Cement products (National Institute of Building Materials of Higher Education), faces the participants of inorganic non-metallic materials and civil engineering from whole country, is a very important science and technology competition in building materials field held every two years to exercise scientific research and practice ability of college students. Since it was firstly held in 2008, it has successfully completed six consecutive events. Among them, the third event in 2014 was undertaken by Chongqing University. At present, this competition has become the highest level competition in the field of concrete material design for national college students in.
The competition attracted a total of 144 teams from 80 domestic top colleges and universities in civil engineering and materials science such as Chongqing University, Tongji University, Southeast University, Central South university, South China University of Technology, Harbin Institute of Technology, Beijing Jiaotong University, Wuhan University of Technology, Xian University of Architecture and Technology, Beijing University of Civil Engineering and Architecture, etc. The competition lineup was strong and unprecedented
The theme of this competition is to prepare C40 flow concrete with good durability using mechanized sand with the consideration of the engineering application environment and economy, showing the ability of college students to solve complex engineering problems. After theoretical examination, mix ratio design, practical operation and other competitions, which was very challenging for the participating students and teachers, the theoretical knowledge level of the participating teams, the scientificity, rationality and innovation of the mix ratio design, as well as the standardization and adjustment ability of the practical operation was assessed.
After more than two months of careful preparation and hard training, two teams from the undergraduate major of Materials Science and Engineering (Building Materials) of school of Materials Science and Engineering of Chongqing University finally made their excellent performance recognized by the professional judges and achieved excellent results. The team composed of students Yuanhao Dong, Yang Liu and Qing Shen won the special prize of this competition. The team composed of students Yuanliang Ren, Ling Yang and Lijuan Chen won the first prize of this competition. Zhirui Zhang and Linwen Yu were awarded as excellent instructors.
In the competition, teachers and students from our university carried forward the school's fine tradition of "Endurance, Thrifty, Diligence and Patriotism", organically combined professional theoretical knowledge with application practice, improved the comprehensive application ability of the learned knowledge, and cultivated the creative spirit and team spirit. At the same time, the influence of material science discipline of Chongqing University in the academic field and the confidence of promoting the construction of double first-class major of the college was greatly enhanced.
