摘要

在本研究中,使用烧结的粉煤灰骨料制备了粉煤灰基透水混凝土(FPC)。使用的材料包括OPC I型水泥、尺寸为4.75、9.5、12.5mm的粗骨料、水和高效减水剂。使用这些材料,开发了水灰比分别为0.30、0.35和0.40的各种混凝土混合物。研究了这些参数对透水混凝土力学性能的影响,如抗压强度、抗弯强度、抗拉强度、渗透性、孔隙率、耐磨性和可浸性。试验结果表明,与天然有效骨料相比,粉煤灰烧结骨料制备的透水混凝土材料具有更好的力学性能。此外,SFA骨料混凝土的抗压强度范围为7.15至17.40MPa,孔隙率范围为26.79至34.05%,可作为环保混凝土使用。

Use of sintered fly ash aggregate in pervious concrete
In the present study, fly ash-based pervious concrete (FPC) is fabricated using sintered fly ash aggregates. Materials used include OPC Type I cement, the coarse aggregate of size 4.75, 9.5, 12.5 mm, water, and superplasticiser. Using these materials, various concrete mixtures were developed with a water to cement ratio of 0.30, 0.35, and 0.40, respectively. The effect of these parameters on the mechanical properties of the pervious concrete such as compressive strength, flexural strength, tensile strength, permeability, porosity, abrasion resistance, and leachability is studied. The test results showed that pervious concrete materials made with sintered fly ash aggregates had a better mechanical as compared to natural available aggregate. In addition, the concrete with SFA aggregates could achieve compressive strength ranges from 7.15 to 17.40 MPa with porosity range from 26.79 to 34.05% and these can be adopted as an environment-friendly concrete.
