Permeability and Strength of Pervious Concrete According to Aggregate Size and Blocking Material

The purpose of this study is to identify the differences in porosity and permeability coefficients when mixing ratio aggregates different present satisfying strength requirement compressive specified a specification Korea. Three mix ratios were suggested by considering various aggregate sizes three cylinders made for each ratio. porosities those evaluated through compression water test, measuring weight specimens underwater analysis pictured Computed Tomography (CT) image. Experiments have shown that it best 50% 5–10 mm aggregates, 45% 2–5 5% sand terms permeability. In addition, as proportion fine increased, decreased. Moreover, effectiveness maintenance method was also examined study.
