概要

ECC is a pseudo-strain-hardening, highly ductile cementitious composite. However, the major studies on this material have been limited to laboratory scale without experience in full-scale plants. Thus, practical applications of ECC have not been previously investigated. In the current study, full-scale processing experiments were executed, and mechanical and fresh properties were tested, where emphasis was placed on two types of tensile test. It was thus proven that ECC can provide excellent fresh and mechanical properties in full scale production, and a statistical basis for determining tensile property specifications was provided. Furthermore, it was found that flexural tests can be utilized for inspecting tensile properties in daily production. These experimental data were reflected in an actual building construction project that was designed to utilize ECC structural elements. As a result, ECC element production was successfully achieved with the required quality in this project.
