摘要:
透水混凝土作为环境友好型材料,被广泛应用于各种基础设施,其在结构性能方面极具特殊性(如高孔隙率等),因而长期服役极易导致其物理性能和耐久性能降低。采用再生骨料制备透水再生混凝土,设计四因素三水平正交试验,采用极差法分析再生骨料替代率、颗粒级配、水灰比、目标孔隙率对透水再生混凝土抗压强度和渗透系数的影响规律。试验结果表明:当再生骨料替代率为50%、颗粒级配为3∶1、水灰比为0.3、目标孔隙率为18%时,透水再生混凝土物理性能表现最佳,其抗压强度和渗透系数分别为26.2 MPa、2.3 mm/s。研究结果可以为透水再生混凝土的制备提供依据。
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.
