摘 要:为建立透水混凝土抗压强度与透水系数的定量关系模型,制备了透水混凝土试件,并测试了试件的有效孔隙率、透水系数和28 d抗压强度。结合现有模型,建立了基于Griffith断裂理论的数学关系模型,并验证了模型的有效性;基于本文提出的模型,选取合适参数,可以对透水混凝土性能进行有效预测。
Abstract: In order to establish a quantitative relationship model between the compressive strength and the permeable coefficient of pervious concrete, pervious concrete specimens were prepared through laboratory tests, and the effective porosity, permeable coefficient and 28 d compressive strength were measured. Combined with the existing model, the mathematical relation model based on Griffith fracture theory was established and the validity of the model was verified. Based on the model proposed in this article, selecting appropriate parameters can effectively predict the performance of pervious concrete.
