| Outline of Final Research Achievements |
The purpose of this study is to develop new cementitious materials that are capable of keeping expanding over a long time in a stable manner. Long-term stable-expansive HPFRCC (High Performance Fiber Reinforced Cement Composite) was developed by combining expansive additive, non-explosive demolition agent and alkali-reactive aggregate. A testing method to evaluate the expansive properties of the long-term stable-expansive HPFRCC was proposed. Artificial aggregates made of the expansive HPFRCC was mixed into concrete to produce cracks like ASR (Alkali Silica Reaction) cracks. Concrete specimens with cracks were used for examination of the injectivity of epoxy-resin into ASR cracks.
