The Institute was originally established in July 1965 as the "Japan National Council on Concrete" with "Japan ACI" the Japan Chapter of the American Concrete Institute formed in 1962 as a nucleus.  Approval for incorporation was received from the Minister of Construction in 1967.  The name of the organization was changed in May 1975 to "Japan Concrete Institute (JCI)" as it is known today.


The organization is a nonprofit corporate body as defined in Article 34 of the Civil Code and is under the jurisdictin of Ministry of Land, Infrastructure and Transport Government of Japan..


The categories of members are Regular Member (Individual person), Class 1 Organization Member and Class 2 Organization Member.

Regular Member:  A person of learning and experience concerning concrete or a person engaged in work closely related to concrete engineering(Present number:   approx. 7600)

Class 1 Organization Member:  A public agency, academic society, or association dealing with concrete.  (Present number:  approx. 45)

Class 2 Organization Member:  An organization supporting the objective and activities of the Institute.  (Present number:  approx. 320)


Officers consist of one President, these Vice Presidents, 24-29 Directors and two Auditors, with approximately one half elected every two years.  Current President and Vice Presidents are

President Yoshihiro Masuda
Prof. Utsunomiya University
Vice Presidents Taketo Uomoto
Professor, Shibaura Institute of Technology
Shigehiro Kobayashi
Managing Exective Officer, Sumitomo Osaka Cement Co. Ltd
Hirozo Mihashi
Professor, Tohoku Institute of Technology


The General Meetings of the Board of Directors are the resolutionary organs of the Institute, with the President, Vice Presidents and the Executive Directors as executives.  The various undertakings and research activities are carried out by the respective committees concerned.


The Institute, as the parent body for promoting research concerning concrete, has the purpose of carrying out investigation and research on concrete, reinforced concrete, other types of concrete and varius materials and equipment related to concrete, and through coordination of investigations and research and dissemination of the results, aims to further research and advances in technology concerning concrete.

Investigation and research activities

Investigation and research activities are carried out by establishing technical committees according to topics under a permanent "Research Committee".  The results of investigations and research by the technical committees are published as committee reports in the Institute publication, "Concrete Journal".  Otherwise, they are published as guides or standards, and seminars are held to publicize the work.

Besides the above, foreign publications are studied and translated, and introduced in the Institute journal.

Scientific lecture meetings, symposia and seminars

An "Annual Convention" (including a concrete engineering lecture meeting) at which researchers and persons concerned with concrete in various fields in Japan gather together to present their research work is held annually.  Symposia and seminars of national and international level on the latest research topics  are held from time to time.

Publication of Institute journal and other materials

The official Institute publication, "Concrete Journal" (approximately 100 pages) is published monthly and distributed free of charge to members.

"Concrete Research and Technology" (approximately 100 pages in Japanese) is published three times per year and distributed free charge to members.

Education literature regarding concrete technology is published as a series, "Concrete Engineering Books" in addition to which study results of various research committees are published in the form of reports or data books.

Journal of Advanced Concrete Technology (ACT) is a new inter-national journal, being launched under the auspices of the JCI. ACT will publish chiefly original research contributions and discussion of previous articles. Invited review articles, selected articles from JCI conferences and case studies may occasionally be published. Contributions will be abstracted in major indexing services. Please visit a web site of ACT.


Every year research papers or reports appear in the Institute publications are examined.  Those considered to have contributed greatly to the progress and advancement of concrete engineering and technology are honored with "Japan Concrete Institute Awards"

Production of educational video tapes

A series of video tapes (total six cassettes) of an educational nature on concrete and the correct way of handling it for the benefit mainly of those involved with concrete on the job and students is being produced.

Exchanges with overseas organizations

The Institute has had a especially close relationship with the American Concrete Institute from the very beginning and the official publication of the Institute, "Concrete Journal" is the successor to the Japan ACI publication, "Concrete Journal".

In the Japan-US Joint Seminars co-sponsored by the Japan Society for the Promotion of Science and the US National Science Foundation, JCI and ACI have served as the contact organizations for the respective countries when the theme of the seminar concerned concrete.

JCI was a member of CEB (Comite Euro-International de Beton) from 1970 and continues to be a member of fib (International Federation of Structural Concrete) after the merger of CEB and FIP in 1997.

JCI cooperates with RILEM (International Union of Testing and Research Laboratories for Materials and Structures) by submitting the opinions of the Institute to the various technical committees of RILEM.  JCI has been an associate member of RILEM since 1983.

In May 1993, an agreement of cooperation was signed between KCI (Korea Concrete Institute) and JCI regarding mutual exchange of members and publications, cooperative surveys and research, dissemination of research results, and joint lectures and seminars.

JCI has an "Overseas Liaison Committee" and two Working Groups of fib and ISO.

Concrete Engineer Cortication Test

A "Concrete Engineer Certification Test System" was established in 1970 with the aim of enhacing the technical levels and securing the prestige of concrete engineers of Japan, and qualification tests for "Concrete Engineer Authorized by JCI" are held every year.  Those who have passed the tests and are presently  registered number more than 35,000 Concrete Engineers and 10,000 Chief Concrete Engineers.  These engineers are actively employed at ready-mixed concrete plants, construction sites and other related areas.

Concrete Maintenance Engineer Certification Test

The maintenance and management of concrete structures, which represent a huge amount of accumulated social infrastructure, is an issue of increasing importance. Ensuring the long service life of the myriad existing concrete structures through proper diagnosis and repair requires a large number of engineers with the required diagnosis and repair skills.
To answer this need, JCI established a Concrete Maintenance Engineer Certification Test System and began administering certification tests in FY2001, thereby sending qualified concrete maintenance engineers into society.
To diagnose the degree of deterioration of concrete, concrete maintenance engineers must be skilled in inspection, measurement, assessment, prognosis, and repair. The title of "concrete maintenance engineer" is conferred to engineers who have passed the certification test and been registered by JCI..
