Annual Convention PosterEvery annual convention is promoted by a creative poster designed on given theme. This poster reflects the enthusiasm of the various sponsoring chapters toward the Annual Convention.
JCI is working to expand the way for new possibilities in concrete engineering through the mutual understanding and cooperation of all its members.
JCI is working to expand the way for new possibilities in concrete engineering through the mutual understanding and cooperation of all its members.
JCI actively conducts studies and research on
concrete every year. Study and research themes are
annually solicited from members and selected
through an impartial deliberation process by the JCI
Research Committee. Research findings are either
released in JCI journals or committee reports and/or
announced at reporting sessions.
JCI publishes monthly Concrete Journal and
presents a multifaceted range of information
including commentaries, technical reports,
construction records, and international information
on a regular basis. Our three annual special issues
have been met with a favorable reception for their
topical themes covering various perspectives.
Concrete Research and Technology and ACT
(Journal of Advanced Concrete Technology) are
posted on the website of “Japan Science and
Technology Information Aggregator, Electronic”
(J-STAGE) at the same time that they are published
for uncharged access. The Japan Concrete Institute have published
guidelines such as "Practical Guideline for
Investigation, Repair and Strengthening of Cracked
Concrete Structures", "Guidelines for Control of
Cracking of Mass Concrete" and "Guidelines for
Assessment of Existing Concrete Structures, and
books like "Fundamentals of Concrete
Technology", "Concrete Diagnosis Techniques"
and "JCI Standards", based on the results of the
activities of its various kinds of committees.
JCI awards include the Honorary Membership Award,
Lifetime Membership Award, JCI Fellow, the Japan
Concrete Institute Awards (Best Paper Award,
Technology Award, Encouragement Award, Work
Award, and Meritorious Deed Award), and the Annual
Paper Encouragement Award, which is presented to
outstanding young speakers by the Annual
Convention Planning Committee. The Honorary
Member Award and various Concrete Institute Awards
conferment ceremony is held as a regular event
following the ordinary general meeting of JCI, and the
Annual Paper Encouragement Award is conferred at
the closing ceremony of the JCI Annual Convention.
Additionally, we are implementing a grant project to
provide support for conducting research on superior
concrete engineering and for the participation fees
for international conferences for presenting papers.
JCI, as an organization that promotes concrete science
and technology, conducts investigative research on a
wide range of subjects including concrete materials
and production, the design, construction, and
management of concrete structures, and new concrete
technologies, through the mutual understanding and
cooperation of all its members, and works to widely
disseminate findings.
Since 1979, JCI has been holding an Annual
Convention once a year (over three days), 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, question-and-answer
sessions, and so on.
Symposiums and seminars on specific
concrete-related research themes are held to
coincide with the publication of Research
Committee reports, offering a forum for research
presentations and discussions for participants,
regardless of whether they are JCI members.
Concrete technology seminars are held every year
in major cities across Japan for the purpose of
spreading concrete technology, teaching new
techniques, and fostering human resources.

JCI Annual Convention
The JCI Annual Convention in three absorbing days filled with
cutting-edge technical and scientific information on concrete.
This annual convention, which was launched in 1979 and will
be held for the 39th time this year, provides a wealth of
information mainly through annual seminars and events such
as Concrete Techno Plaza and Ready-Mixed Concrete Seminar,
as well as special lectures. The three-day program features a
range of activities related to materials, structure, performance,
diagnosis and the environment, and research presentations and
exhibits concerning the latest concretes. It also features original
events organized by the various JCI chapters that involve the
participation of residents, making the convention a festival of
concrete that offers an interesting combination of enjoyable
and serious events. All People involved with concrete are
welcome.
Ready-Mixed Concrete Seminar
The Ready-Mixed Concrete Seminar introduces various techniques and studies for better ready-mixed concrete production. Every time it is held, this seminar attracts a large audience.
Concrete Techno PlazaThis event offers a venue for the many diverse companies that support concrete technology, including cement, admixture, and machinery manufactures, general contractors , and design consultants, to exhibit their latest technologies and products.

The importance of adequately protecting and maintaining the enormous
stock of concrete structures built over more than half a century will only
increase as time passes. To ensure that this need can be met, JCI has been
promoting the systematization of engineering knowledge in new fields such
as the diagnosis, maintenance, and repair of existing concrete structures,
and along with the publication of Concrete Diagnostic Techniques, a
textbook for authorized concrete diagnosis & maintenance engineer
workshops, established the Concrete Diagnosis & Maintenance Engineer
Certification System in 2001. Since then it has been administering
qualification tests for concrete diagnosis & maintenance workshop
graduates (who are eligible to take the qualification test within 2 years of
graduating), producing over 12,300 certified Authorized Concrete Diagnosis
& Maintenance Engineer.
JCI has established collaborative relationships with concrete-
related organizations throughout the world.
1. ACI (American Concrete Institute) ... JCI having been originally established with the Japanese chapter of ACI, it continues to have to
this day a particularly friendly relationship with ACI, and concluded an
international partnership with ACI in 2004.
2. RILEM (International Union of Laboratories and Experts in Construction Materials, Systems, and Structures) ... JCI joined RILEM as
an organization in 1982. JCI signed an international partnership
agreement with RILEM in 2007.
3. ISO/TC71 (International Standards Organization/Technical Committee 71 (Concrete, Reinforced Concrete and Prestressed
Concrete)) ... JCI is the deliberative organization for TC71. (1988:O
member, 1994:P member)
4. KCI (Korea Concrete Institute) ... JCI concluded an exchange agreement with KCI in 1993.
5. fib (International Federation for Structural Concrete) ... JCI became a Delegation 4 Class fib member along with the Japan Prestressed
Concrete Engineering Association in 1998.
6. ACF (Asian Concrete Federation) ... JCI actively supported the establishment of ACF and is serving as its first chair country.
7. IMCYC (Mexican Institute of Cement and Concrete) ... JCI signed an international partnership agreement with IMCYC in 2005.
8. IBRACON (Brazilian Concrete Institute) ... JCI signed an international partnership agreement with IBRACON in 2006.
9. TCA (Thailand Concrete Association) … JCI signed an International partnership agreement with TCA in 2016.
10. CIA (Concrete Institute of Australia) … JCI signed an International partnership agreement with CIA in 2016.

JCI established in1970 the Authorized Concrete Engineer and Authorized
Chief Concrete Engineer Certification System for the purpose of raising the
technical level of concrete engineers, and since then has been administering
qualification tests every year, certifying thus far a total of approximately
55,200 people.
The majority of the authorized concrete engineers and authorized chief
concrete engineers certified by JCI are working in various positions in
ready-mixed concrete production, product quality control, construction, and
soon, across Japan, and have earned a high level of trust as engineers with
concrete expertise gained through many years of work in their respective
fields.
