Applications of SHCC in Japan – Tools and Tips for Promoting its Use
This paper reviews the progress of SHCC applications in Japan and describes suggestions for spreading the use of SHCC. An example of the steps of research activities to be taken for utilizing a new cementitious material is described. As the first step, fundamental and reliable research data should be accumulated to establish the production and construction methods. As the second step, assessment test methods for characteristic performances should be established, while formulating draft recommendations for design and construction incorporating the performances. As the third step, ideas for application making use of the performances should be proposed, and application should be carefully commenced, beginning with small-scale projects. The results of a hearing survey are reported regarding obstacles to the application of new maintenance techniques. Major obstacles for engineers of the ordering parties include the troublesome task of explaining the necessity of adopting the new technique and the issue of responsibility when troubles occur. When developing a cementitious material with high performance, the following conditions should be met: (a) the material is clearly competitive in performance and (future) cost in comparison with conventional materials; (b) its characteristic material performance can be simply quantified and incorporated in the design; (c) a construction method to ensure the effect of its characteristic material performance has been established; and (d) it is an effective material to cope with a serious problem that is present.
