Title :さんご砂利コンクリートに関する研究 1
Title alternative :Study on Coral Finger Concrete 1
Authors :具志, 幸昌
Authors alternative :Gushi, Yukimasa
Issue Date :Apr-1969
Abstract :In previous study, it was reported that the coral finger concrete had enough strength to be used in ordinary concrete works, and that it had a strong segregatin property which was a origin of the difficulty in handling and placing the concrete. This report is the story of the properties and the behavior of the coral finger concrete ih which a kind of AE agents are contained. On accout of using the AE agent, the water contents of coral finger concrete can be reduced in greate degree, and the segraegtion property can be diminished. The entrained air so improve the workability of the concrete that the cement content can also be reduced. The difficulty in practical handling of the concrete, pointed out in the previous report, is eliminated. Other properties of the coral finger concrete in case of using the AE agent, such as unit weight of the concrete, the c/v~σ28 relation etc, are also discusseed in this report.
