【TENTATIVE】 With the transition to the class system in 1976, the predecessor "Civil Engineering Materials Engineering" course was taken over as a "Structural Materials Engineering" educational subject as one of the Class 4 Building Structural Engineering Courses, and structural materials engineering research. A room has been set up. At the time of 1970, it was composed of Associate Professor Minoru Funakoshi and Assistant Professor Ashuo Yonekura, who was conducting research on the shear strength of reinforced concrete beams and lightweight concrete. Assistant Yonekura studied drying shrinkage and creep of high-strength concrete as an assistant at Tokyo Institute of Technology from 1975 to March 1978, and returned to Hiroshima University as a lecturer in April 1978. did. In 1975, with the transfer of Assistant Yonekura, Assistant Professor Kakuhisa Okamoto was hired, and Assistant Professor Funakoshi and Assistant Professor Okamoto conducted research on the torsional strength of reinforced concrete beams in addition to research on the shear strength of reinforced concrete. .. Professor Funakoshi, who was promoted in 1981, moved to Hosei University in the same year, and Assistant Okamoto moved to Tokyo Institute of Technology in February 1982.

In April 1982, Professor Eiichi Tazawa was appointed from the Taisei Institute of Construction Technology, and at the same time, Assistant Shingo Miyazawa was appointed immediately after graduating from Tokyo Institute of Technology. Professor Tazawa conducted a wide range of research such as temperature stress of concrete, new mixing method (double mixing), alkaline aggregate reaction, research of fluidized concrete using high-performance water reducing agent, and was promoted in 1982. Assistant Professor Yonekura studied the drying shrinkage and creep of concrete using various admixtures, and the torsional strength of prestressed concrete (PC) beams. Assistant Professor Miyazawa and Professor Tazawa and Assistant Professor Yonekura conducted research on fluid concrete, the strength and deformation of reinforced concrete columns that have undergone an alkaline aggregate reaction, and the torsional strength of PC beams. In addition, Professor Tazawa and Assistant Miyazawa discovered for the first time in the world self-shrinkage associated with the hydration reaction of cement, and this self-shrinkage may cause cracks that were previously thought to be caused by temperature stress due to heat of hydration. I also clarified that there is something. Assistant Professor Yonekura studied bending, shearing, and torsional strength of PC beams using continuous fibers such as carbon fiber, developed high-tension PC members obtained by triaxial restraint, and reinforced existing structures by triaxial restraint. I was promoted to a professor in October 1993 after conducting research focusing on such things.

From April 1991, Assistant Professor Kawai Lab was appointed after obtaining a degree in the doctoral course at the Graduate School of the University of Tokyo to study substance transfer, alkaline aggregate reaction, and carbonation phenomenon inside concrete, and microorganisms with Professor Tazawa. We studied the deterioration of concrete, the dirt on the concrete surface, and the hydration reaction process of cement. In April 1995, Assistant Professor Miyazawa moved to Ashikaga Institute of Technology (currently Ashikaga University) as an assistant professor.

Professor Tazawa is energetically working on the self-shrinkage associated with the hydration reaction of cement, and is proceeding with research on the mechanism of self-shrinkage, prediction method, control technology, etc., and in 1998, on self-shrinkage. An international workshop was held in Hiroshima.

Assistant Professor Kawai conducted research on material transfer inside concrete, microbial deterioration of concrete, and environmental load evaluation of concrete. From July 1997 to July 1998, America North I studied abroad at Western University as an overseas researcher.

In March 1999, Professor Yonekura moved out as a professor at Hiroshima Institute of Technology, and in April of the same year, Professor Ryoichi Sato from Utsunomiya University and Assistant Yusuke Baba from Tokai University took office. In March 2000, Professor Tazawa retired from retirement age. Professor Sato conducts research on improving the performance of concrete, evaluating the behavior of structural members, evaluating the time dependence of concrete structural members, controlling cracks in continuous reinforced concrete pavement, and improving the performance of concrete structural members using waste. We worked on it and achieved practical application for the first time in Japan and overseas.

Assistant Baba conducted research on hydration shrinkage of cement, transferred to NMB Co., Ltd. (currently Chigasaki Technology Development Center Co., Ltd.) in March 2001, and completed the doctoral course at Utsunomiya University. Assistant Yang arrived in April of the same year. Yang was working on self-shrinking of high-strength concrete, and in March 2003, he moved to Zhejiang Institute of Technology in China, and Ippei Maruyama, who completed the doctoral course in architecture at the University of Tokyo, was in the same year. I arrived in April. Assistant Maruyama worked on research on reducing self-shrinkage of concrete and controlling cracks. In March 2005, he moved out as an assistant professor at Nagoya University, and dropped out of the doctoral program at Nagoya University. I have arrived. Associate Professor Kawai was promoted to Professor in April 2010, and Assistant Professor Yuko Ogawa was appointed in October 2011. Assistant Professor Ogawa is conducting research focusing on the performance evaluation of fly ash and the utilization of waste tile aggregate as an internal curing material. In March 2012, Professor Sato retired, and in March 2013, Assistant Professor Ishida moved to Ube Industries, Ltd. Mr. Bui Phuong Trinh, who completed the doctoral course at the university, has been appointed as a specially appointed assistant professor from October 2015 and an assistant professor from March 2016. After conducting research, I moved to Ho Chi Minh City Institute of Technology, Vietnam in October 2017. In December 2018, Assistant Professor Riya Catherine George, who completed the doctoral course at Indian Institute of Technology Kanpur, was appointed. Assistant Professor Riya is conducting research on damage identification using the vibration characteristics of members.
