Abstract |
Domestically, application of High Flowing Self-Compacting Concrete (HSCC) is limited to building structures and it if difficult to find examples of application in civil infrastructural constructions. However, In the case of North America and Europe, by introducing precast and prestressed system, HSCC is being used for high-density reinforced bridge members. Hence it is assessed that broadening the utilization of HSCC into areas such as bridges and civil construction is required. Therefore in this research, to apply HSCC to high-density reinforced bridge members, ground granulated blast-fumace slag and fly ash were mixed in binary and ternary systems. Also the dynamical characteristics of HSCC. following 1 st class regulations of Japan Society of Civil Engineers (JSCE), were assessed to enable application on high-density reinforced structures. The test results revealed ter-nary system mixture showed better mechanical characteristics than binary system mixture and the application on high-density reinforced precast bridge members seems possible.
