| Abstract: | Aggregate gradation characteristics has great influence on the optimization of mix proportion design and the basic performance of pervious concrete. Three kinds of aggregates with different particle sizes of A, B and C were used for mixture design test. By large number of experiment data fitting and variance analysis, the correlations between the pervious concrete valid porosity, unit volume aggregate particle number, aggregate specific surface area, compressive strength and aggregate gradation were established. The result is of great significance for the optimization of mix proportion design of pervious concrete and the prediction of basic performance. |
