Abstract In this research, the cracked concrete members are repaired and strengthened by inlaying method to ensure that the concrete members have not less than the initial mechanical properties before cracking. The inlay is made into a dumbbell shape or a shape of 8 characters by metal or composite material. The middle slender part of the inlay penetrates through the crack, and the two ends of the inlay are embedded with the original concrete member to achieve the functions of repair and reinforcement. The test results show that the flexural properties of cracked cement products are significantly improved by using this inlaid reinforcement technology in this research. Moreover, this technology has the advantages of convenient construction, high reliability and low cost.

About author:: Dihong Li obtained his Ph.D. degree in materials scie-nce from Harbin University of Architecture in 1998. From 2000 to 2001, he worked as a visiting scholar at the University of Tokyo in Japan for structural research on armor materials and ship materials. He has been engaged in the teaching and research of polymer-based composite materials for many years. He mainly studies the structural analysis of polymer-based composite materials, structural design, and integrated design of structures and processes. In the past five years, he has undertaken 11 scientific research projects with a total funding of 3.84 million yuan, 3 project leaders, 2.09 million yuan, and 2 national special projects with a total funding of 1.87 million yuan. Since he took office, he has published 43 academic papers and won 9 national invention patents. In the past five years, he has published 21 academic papers, including 4 in SCI and 9 in EI. There are 7 core journals and more than 4 national invention patents.Xian Xia received her B.S. degree in engineering from Xuzhou University of Technology in 2017. She is currently a graduate student in Civil Engineering and Transportation, Beijing University of Civil Engineering and Architecture, under the supervision of Prof. Li Dihong. Her research has focused on structurally inlaid repairing and reinforcement concrete. |
