| Summary: | 碩士 === 正修科技大學 === 營建工程研究所 === 104 === Chemical doping agent is one of essential raw materials: concrete, and concrete is the most traditional engineering materials, almost all engineering are required to use concrete, but concrete shall be parous, transport, pumping, cast on site, maintenance and other multiple operations, caused the quality is not easy to control and easy to have unstable situation. In order to overcome the bad influence of the construction of concrete construction, the quality of the product quality is introduced, and the high performance concrete is introduced to meet the environmental protection and reduce the man-made factors. High fluidity concrete is one kind of high performance concrete and its subsequent evolution modified into self compacting concrete, bridges in our country has many uses more easily placing self filling concrete (SCC) case, especially the bridge pier structure. Discrimination in self filling concrete in domestic application is widely used, this study adopts elevated road project in Kaohsiung harbor couplet outside the approved design strength 350kgf/cm2 self compacting concrete, in the same proportion change G type lignin sulfonic acid series water reducing retarder, can provide liquidity high slump flow mixed concrete special agent and a carboxylic acid polymer, a new generation of mobile agent to do different types of pharmaceutical and adding different dosage and view the results. It is suggested that different types of pharmaceutical suitability of concrete.
