透水再生混凝土配合比设计研究
Mixture proportion design of pervious recycled concrete
摘要
Abstract
Pervious concrete,as an environmentally friendly material,is widely used in various infrastructure applications.However,due to its unique structural characteristics such as high porosity,its physical properties and durability tend to degrade during long-term service.In this study,pervious recycled concrete was prepared using recycled aggregates.A four-factor,three-level orthogonal experiment was designed to investigate the effects of recycled aggregate replacement rate,particle gradation,water-cement ratio,and target porosity on the compressive strength and permeability coefficient of pervious recycled concrete.The range analysis method was employed to evaluate the influence of these factors.The results showed that the optimal physical performance was achieved when the recycled aggregate replacement rate was 50%,the particle gradation ratio was 3∶1,the water-cement ratio was 3∶10,and the target porosity was 18%.Under this optimal mix proportion,the compressive strength and permeability coefficient of the pervious recycled concrete reached 26.2 MPa and 2.3 mm/s,respectively.The findings of this study provide a theoretical basis for the preparation of pervious recycled concrete.关键词
