The purpose of this study is to consider method of improving reliability of compressive strength prediction by face<br/> hitting rebound test hammer and to propose compressive strength reliability expression to apply to face hitting rebound<br/> test hammer. The result is as follows. 25mm size face hitting rebound test hammer was used to observe a correlation<br/> between compressive strength and rebound degree for entire hitting angle direction. so, if method using this hammer is<br/> applied, it will be a method to improve reliability in compressive strength presumption by rebound test method.

Lee, Sang Ryul Moon, Hyo Soo Cho, Han Kwang Kwon, Na Hyun Choi, Jung Sik Ahn, Yong Han Abstract The purpose of this study is to develop a risk breakdown structure by deriving structural and job risks that may occur during the dismantling of radiated concrete structures in nuclear power plants. In order to achieve the purpose, the similarity between nuclear power plant dismantling and construction demolition work was analyzed, and a work breakdown structure was established to derive risk factors for each cutting work type and structural and job risks based on expert interviews. As a result, this study developed a practical risk breakdown structure that can be used when dismantling nuclear power plants.

The purpose of this study is to obtain basic data of the properties of the foamed concrete within purified fly-ash Which is manufactured from raw material of fly-ash so as to make various application of foamed concrete. To find change of the properties according to admixing purified fly-ash as substitution of cement, admixture ratio was increased 20% step by step from 0% to 60% at the amount of 300, 400, 500, 600㎏/㎥ of B(cement+purified fly-ash). The results of study were shown as follow: As the admixture ratio of purified fly-ash was increased with decreasing the value of flow but increasing the value of absorptivity because of its high fineness and trend of the breaking of foam. It would be necessary to check the admixture ratio of purified fly-ash to make up for the KS F4039 with the value of flow, it's minimum is 180㎜. As the admixture ratio of purified fly-ash was increased, the compressive strength was decreased but with aging, it increased dramatically for it's property of pozzolan reaction. This study shows that the admixing of purified fly-ash in foamed concrete is very useful but we have to check the admixture ratio of purified fly-ash to its side effects before using it.
