JOURNAL FREE ACCESSThe Recommendations for Concrete Pumping 2012 by Japan Society of Civil Engineers was published in June 2012. The original “Recommendations for Concrete Pumping” was enacted in 1985 and the first Revision was done in 2000. This revision is its second one. This report describes an overview of transitions of these Recommendations up to the present and key points of this revision.View full abstractDownload PDF (1299K)

JOURNAL FREE ACCESSThis report presents the design and construction of cementitious materials used for the low-level radioactive waste disposal, in terms of the required performance and techniques. Especially from the viewpoint of system performance, long-term durability (e.g. over 10 000 years) of cementitious materials needs to be further investigated. In order to quantitatively verify the design requirement on the low diffusion layer: the leakage speed should be reduced by controlling the diffusion of radionuclides, we determined to use a diffusion coefficient as an index for the verification because it is considered as the simplest way to numerically indicate the diffusion performance of members. We deemed the diffusion coefficient of the layer can be verified by the overall equivalent value which is related to an area ratio of healthy portion to other domains that changed in state due to deterioration.View full abstractDownload PDF (1928K) -

JOURNAL FREE ACCESSThis paper reports the first-year activity of JCI-TC 115 FS “Research Committee on Diagnosis of ASR-affected Structures”. An attitude survey was carried out in order to investigate the recognition of concrete engineers in regard to current preventive measures and diagnosis of ASR-affected structures. From the results, more than half of respondents recognized that it is required to establish the preventive measures appropriate for priority of the structure. The results also indicated that the preventive measures should be established by considering the balances between risk and cost.View full abstractDownload PDF (1234K) -

JOURNAL FREE ACCESSThe surface quality of the concrete structure is very important, because it would decide the durability performance of concrete structures. And the surface quality would be greatly influenced by the skill of construction. But now, the PDCA cycle for improving the quality doesn't rotate well, since the rationalized evaluation method on the surface quality has not existed. Therefore, a new evaluation method on the surface quality using the visual test has been studied in order to evaluate correctly and to improve the quality of concrete structures. This paper describes the existing problem of evaluation methods, any details on a new evaluation method and its effects.View full abstractDownload PDF (1861K)
