| Outline of Final Research Achievements |
This research aims to develop the functional concrete using waste tire, which can restrict the Alkali Silica Reaction. Tipped the waste tire into small particles, variation of mechanical properties of mortar and concrete were evaluated with changing the particle sizes and replacement ratios. From the results of mortar bar test, one of the ASR test method, mortars including waste tire tips never showed the restriction effect of expansion due to ASR. Oppositely, expansion ratio of them were larger than that of non-contaminant specimen. This result indicated very important information about replacement ratio of waste tire tips that larger than 10% replacement ratio of waste tire tips generated the structural weak point in mortar matrix. It was estimated that replacement ratio of waste tire should be less than the volume of entrained air. Further experiment can be advanced based on the results above in the future.
