RESEARCH ON APPLICATION OF RECLAIMED AGGREGATE PERVIOUS CONCRETE BASE BASE BASED ON SPONGE CITY
In order to promote the construction of sponge city,alleviate the problem of urban waterlogging,and realize the natural accumulation and infiltration of rainwater,the application of recycled aggregate pervious con-crete in the basic construction of sponge city was deeply and systematically studied.According to the core concept of volume method,the mix ratio scheme of recycled aggregate pervious concrete is designed.The pervious concrete was prepared and cured by the method of mechanical mixing and vibration forming.The large pore surface structure of reclaimed aggregate pervious concrete base based on sponge city is designed to achieve good pervious effect and structural performance.Through the analysis of practical engineering application,it can be seen that the reclaimed aggregate permeable concrete base has remarkable efficient voidage characteristics,which can effectively improve the permeable performance of pavement.
