Reinforced Concrete Buildings in the Near FutureA. Baba, A. Mori2001 Volume 39 Issue 7 Pages 3-8
Published: July 01, 2001
Released on J-STAGE: April 26, 2013
JOURNAL FREE ACCESSA new form work system is dealt with herein. Thin cementitious sheathing panels produced by extrusion molding are developed for the system, which are excellent in flexural strength and durability. A modular coordination system for the form work, quality control method, and actual properties are introduced. The features of the system are characterized as saving human power, improving durability of the buildings, so that sustainability of constructing reinforced concrete buildings and humanizing the construction labor.View full abstractDownload PDF (4899K) -

JOURNAL FREE ACCESSThe Building Standard Law of Japan and its Enforcement Order were revised in June 2000. The main point of this revision is that the contents of provisions changed into performance code from specification code. At the same time, the notifications defined by the Ministry of Land, Infrastructure and Transport (MLIT) were improved, and the new notification (Notification No. 1446) was also added. Owing to this revision of these Law, Order and Notifications, it became impossible to use the concrete like the nonstandardized goods of JIS A 5308 (Ready-Mixed Concrete) -1998 and the high strength concrete, if it is not obtained Minister's Approval.
This paper explains the contents of this revised Building Standard of Law and its Enforcement Order, and describes how the revised Standard Law defines the building structural concrete.View full abstractDownload PDF (1912K) -

JOURNAL FREE ACCESSDurability of the salt damage to reinforced concrete and prestress concrete structures has now become a very important subject. Accordingly, it would be necessary to clarify the effect of the concrete mix materials on the process of chloride-induced corrosion of concrete. The chemical admixtures such as superplasticizer have been developed, and the mineral admixtures such as blast furnance slag are now indispensable for production of high-flowability concrete and high-strength concrete. Considering the above situations, this study is base research aiming at effect of differences in the major constituents of superplasticizers and mineral admixtures on the processes of chloride ion penetration and binding in hardened mortar.View full abstractDownload PDF (8573K) -

JOURNAL FREE ACCESSIt is always discussed as a new and an old theme that the finished concrete architecture is a good finishing method of reinforced concrete architectures or not. The theme is also discussed from a viewpoint of the conservation of cultural worthy architectures built in modern ages. The author will try to discuss the theme from a cultural view going back to the starting point of the concrete architecture. In the report, he traces back to an architect's mind as a genealogy of three architects : August Perret, Antonin Raymond and Makoto Masuzawa.View full abstractDownload PDF (18650K) -
