| Abstract: | The article describes the problems in the application of high-performance concrete, mainly including compatibility between cement and super-plasticizer, the bleeding of just mixed concrete, the selection of coarse aggregate and the designing methods of mixing proportion. It simultaneously analyzes the causes of these problems and solutions. Based on the experiment and analysis, it makes suggestions to enhance the appearance and quality of high-performance concrete. |
