Japan Concrete Institute Membership

Since our establishment as "Japan National Council on Concrete" in July 1965, we have made efforts to academic and technological development related to concrete in Japan, together with a large number of concrete engineers and organization participants. Today, we have now built a robust position both domestically and internationally, as an academic organization specialized in concrete with more than 75,000 members, consisting of people engaged in concrete-related business, as well as academia and research institute.

In light of such performance, we became certified as "Public Interest Incorporated Association" according to the laws related with public interest incorporated association reform enacted in December 2008, and the name was changed to "Japan Concrete Institute (public interest incorporated association)" in April 2011.

In order to improve technologies of concrete engineers in Japan and secure their positions, Japan Concrete Institute established the "Authorized Concrete Engineer (Authorized Chief Concrete Engineer) Qualification Test System" in 1970, and the "Authorized Concrete Diagnosis and Maintenance Engineer Qualification Test System" in 2001, where qualification exams are annually implemented. A number of concrete engineers who have been certified by those exams are actively working in ready-mixed concrete plants and construction sites, and they are highly appreciated from various quarters.

As described, Japan Concrete Institute offers a forum for mutual understanding and collaboration for those with the same purpose beyond difference of positions and fields, so we welcome researchers and engineers to JCI membership who forge the future of concrete industry.

(2) Operation

Decision-making bodies of the Institute are the general assembly and the board of directors, which are executed by the president, vice-president and the relevant director, and are audited by the auditor and accounting auditor. Business operations and research activities are conducted by individual committees.

Purpose and business

As a parent organization that promotes concrete science and technology, JCI has the objectives to conduct survey and study on concrete, reinforced concrete, various types of concrete and materials and machineries associated with concrete, as well as to promote research and improve technologies related to concrete, by disseminating the results. The businesses of the Institute include the followings;

(1) Study and research activity

The Institute conducts study and research activity, by establishing technical committees on each topic under permanent research committee. The outcomes of individual committees are published in the proceedings of the Japan Concrete Institute as a committee report, issued as a guideline or a report, or disseminated through workshops.

(2) Academic lectures, symposiums and workshops

JCI holds a Japan Concrete Institute Annual Convention, which is attended by concrete researchers and engineers from various fields, giving them the opportunity for lively exchanges of information through reports on research findings. In addition, various workshops on popular topics and technical tours to construction site are offered for members in the convention.

(3) Issuing monthly and technical journals

JCI publishes monthly journal "Concrete Technology" (approximately in 100 pages) and distributes it to its members, free of charge. The journal contains latest research and technological information, such as general remarks, explanations, technical reports, construction records, and literature search by experts of the field. Three annual special issues address in-depth topical theme, which acquire good reputation. JCI also publishes a technical journal of Concrete Research and Technology triannually, and distributes it to the members (free of charge).

(4) Publishing books

JCI publishes "Overview of Concrete Technology", a practical guide to concrete technologies "Concrete Diagnostic Techniques", a textbook of diagnosis and repair of existing concrete structures "Practical Guideline for Investigation, Repair and Strengthening of Cracked Concrete Structures 2009", a JCI's guideline, and English technical Journal "ACT (Journal of Advanced Concrete Technology)". In addition, JCI summarizes research outcomes and materials by individual technical committees, and distributes them to the members.

(5) Awards

JCI presents "Concrete Institute Awards (including Merit Award, Best Paper Award, Technology Award, Encouragement Award, and Work Award)" to articles, reports, pieces of work and members which are recognized to have remarkably contributed to promotion and development of concrete engineering and technology.

(6) Authorized Concrete Engineer Qualification Test

JCI annually administers qualification tests of "Authorized Concrete Engineer" and "Authorized Chief Concrete Engineer", for the purpose of raising the technical level of concrete engineers, as well as improving reliability of concrete and hence contributing development of concrete related industry. The titles of "Authorized Concrete Engineer" or "Authorized Chief Concrete Engineer" shall be given to those who have passed the test and registered (the certificate expires in four years, and must be renewed every four years). "Authorized Concrete Engineer" refers to engineers who are capable to conduct routine technical operations including manufacturing, construction, test, inspection and supervision of concrete, and "Authorized Chief Concrete Engineer" refers to those who are highly capable to conduct planning, management and instruction of concrete manufacturing, construction and research.

(7) Authorized Concrete Diagnosis and Maintenance Engineer Qualification Test

The importance of adequately maintaining the enormous stock of concrete structures will increase as time passes. A large number of engineers who owns diagnostic and repair techniques are needed, so that existing concrete structures are properly diagnosed and repaired for longer use. "Authorized Concrete Diagnosis and Maintenance Engineer" is an engineer who has a specialized knowledge in survey, measurement, judgment, prediction and repair of concrete, and an ability to diagnose deterioration of concrete. The title of "Authorized Concrete Diagnosis and Maintenance Engineer" shall be given to those who have taken workshops, passed the test, and registered (the certificate expires in four years, and must be renewed every four years).

How to apply

An application form (downloadable from the website) must be filled out and submitted to JCI (see application form for account information), with a copy of receipt for payment of entrance fee and membership fee. The amount for full member and student member are 13,000 yen (1,000 yen of entrance fee and 12,000 yen of annual fee) and 7,000 yen (1,000 yen of entrance fee and 6,000 yen of annual fee), respectively.
