Abstract
According to the principle of the accumulation of aggregate and particle interference theory, mixing design method, experimental research and analysis through an analysis of the use of pervious concrete aggregate gradation test. They were established aggregate gradation and aggregate porosity unit volume aggregate number of particles, the regression equation between the aggregate surface area. Based on pervious concrete mix design features in-depth analysis of the relationship between the parameters and principles of performance and mechanical properties of porous concrete between the constituent materials; and selecting suitable raw materials, optimizing pervious concrete material, permeable to determine the best ratio of concrete; Finally, life cycle environmental assessment system, ordinary concrete, pervious concrete and pervious concrete high performance environment coordination of the evaluation carried out. Through this high- performance pervious concrete mix design and study the life cycle environmental evaluation system, we draw some important conclusions of the study, to promote engineering applications pervious concrete has a certain reference value.
