概要: 金沢大学大学院自然科学研究科環境創成<br />金沢大学薬学部<br />In recent years, there have been many attempts to reuse molten slag. Mo lten slag is obtained through further treatment of incinerated ash produced in the disposal process of garbage or sewage sludge and is used in building materials, such as brick. To establish the safety of such slag, its physical properties and metal contents were investigated in this study. After examining the physical and chemical characteristics of 13 forms of slag made using different methods, no differences were observed and it was judged that reuse is possible. There was little elution of toxic metals in the elution test when water was used as a solvent. On the other hand, when acid and alkali were used, the elution of toxic metals tended to become greater. © 2004 The Pharmaceutical Society of Japan. 続きを見る

概要: In the Hokuriku district in Japan, large numbers of concrete structures have been suffering from damage caused by alkali silica reaction (ASR). Some huge volcanoes are located within this district, and the headwaters of main rivers prompt the outflow and spreading of volcanic rocks such as andesite, rhyolite and tuff stones, which are the main volcanic reactive stones causing the serious damage of ASR in the entire area. To solve this problem effective countermeasures such as repair and strengthening methods should be established. One intake tower in this area had deteriorated due to ASR, and deformation had occurred as a consequence of ASR ex-pansion of the concrete. Countermeasures were carefully considered by academic experts, and post-tensioned tendons were inserted into the intake tower concrete (vertically oriented) so that the power station can continue to operate safely in the future. This is thought to be the first challenge of its type anywhere in the world for which the deformation of a real structure caused by ASR expansion must be controlled. In this paper, the results obtained from laboratory tests using reactive aggregate and the overview of the investigation and the method of the reinforcement including the effect of the countermeasures will be discussed.<br />出版者照会済 続きを見る

概要: 金沢大学理工研究域環境デザイン学系<br />A large number of bridge piers on the Noto highway are now suffering from serious damages c aused by alkali-silica reaction (ASR). The Kashima Bridge with a 2-span steel girder structure was constructed in 1978. However, in the inspection carried out in 2004, it was found that half of stirrup steel bars in the pillow beam fractured at the bending corner of steel bar due to the excessive ASR expansion of concrete. For this reason, the pillow beam of the Kashima Bridge was completely reconstructed by removing all the concrete in 2005. In the first part of the paper, the execution procedure of reconstruction of pillow beam and the strengthening of column in ASR-affected RC pier were introduced. In the second part of the paper, in order to recycle concrete rubbles from the Kashima Bridge, the possibility of recycled aggregates for residual ASR reactivity and its some countermeasures were also discussed. © 2008 Taylor & Francis Group.全文公開200909 続きを見る

概要: In the Hokuriku district, the effort toward the production of highly durable concrete mixtures using classified fine fly ash has just started as a part of ongoing countermeasures for the chloride attack and the alkali silica reaction (ASR). At a time when ASR deterioration phenomena are still progressing, the use of fly ash cement in concrete should be recommended and assertively be adopted as a regional approach for the mitigation of ASR problem especially in the Hokuriku District. In order to promote this mutual understanding and cooperation among the electric power companies, the national and local governments, the industrial association of ready-mixed concrete companies and the universities are indispensable. Accordingly, a joint-collaborative industry-academia-government research committee has been set up in January 2011. This paper focuses on the drawing from the current stage of ASR problem in the Hokuriku district and the development of highly durable fly ash concretes as its countermeasures. 続きを見る
