| dc.title | Evaluation of smaller cubes and cores for high strength and very high strength concrete | en_US |
| dcterms.abstract | In the current Code of Practice used in the construction industry in Hong Kong, the capacity of structural members is assessed from the results of compaction test of 150mm concrete cubes and cores. However, as the high strength and very high strength concrete are becoming popular in the construction industry, testing of 150mm cubes and cores becomes impractical due to the limited capacity of current compression machines available in the Hong Kong. In fact taking 150mm or 100mm cores from the structures will damage the structural integrity of these structures. Therefore, the drafting committee of the Code of Practice for Reinforced Concrete structures in which the supervisor of this project is a member has to look at a new acceptance criteria by using smaller concrete cubes and cores for testing. However, local data on the reliability of smaller size specimens are scarce. More information regarding the relationship between the smaller cubes and cores is necessary. In order to provide more data for the consideration by the drafting committee, the work described in this dissertation is to investigate the relationship and to establish the testing standard of smaller size cubes and cores for normal strength, high strength and very high strength concrete. A statistical approach is adopted to assess the size effect of cubes and cores strength. From the study, the acceptance criteria of smaller cubes and cores for normal strength, high strength and very high strength concrete are recommended. | en_US |
