Survey/research on concrete, which constitutes a core aspect of the activities of the Japan Concrete Institute (JCI), is carried out by technical committees for specific topics organized under the Research Committee administered by the Science Committee. The subjects of research are publicly collected from JCI members and selected by the Research Committee. About five subjects are adopted every year to be studied basically for two years. About ten technical committees are therefore active ever year. In the 2010 fiscal year that began in April, ten technical committees are in operation in their respective spheres.
A wide spectrum of topics engaging researchers’ interest is studied by technical committees, including problems arising in concrete engineering and subjects offering new technical perspectives. The achievement of each committee is summarized in a report to be published, with training sessions and symposiums being held based on such a report. Some of the study results may be proposed as standards and recommendations. International conferences and symposia have also been actively held based on the achievements of JCI’s technical committees. One of those symposia was held last year, and one, this year. Summarized study results are also briefed in the institute’s annual convention in July every year.
Four technical committees on the following subjects were concluded by March 2010:
(1) Minimization of Global Warming Substrances and Wastes in Concrete Sector (Chaired by Koji Sakai)
(2) Overseas Standards and Requirements for Concrete Materials (Chaired by Taketo
(3) Reduction of Shrinkage Cracks and Durability Enhancement from Viewpoints of
Mineral Admixtures (Chaired by Toyoharu Nawa)
(4) Performance-Oriented Seismic Rehabilitation (Chaired by Shunsuke Sugana)
The Japan Concrete Institute strives to expand the international scope of its activities and deepen exchanges with international institutions including ACI. Since the above-mentioned topics are timely and of international interest, the achievements of the committees should not be enclosed within the boundaries of Japan. It is JCI’s responsibility to the international community to make them available to the world for the promotion of concrete studies. As it is currently difficult to translate all of the reports into English, it was decided to translate a digest edition to be delivered worldwide. Technical Committee Report 2007 – Digest Edition was published in 2007 as the first issue of this annual publication. Now we are pleased to present Technical Committee Report 2010 – Digest Edition as issue No. 4.
We truly hope that this digest report will contribute to the promotion of studies on concrete worldwide and serve as a tool for international research cooperation.
