WebThe tested samples were prepared at dry densities of 1.37 g/cm 3 and 1.67 g/cm 3, and the corresponding void ratios are 0.932 and 0.591, respectively. So, the porosities of the two samples are 0.4824 and 0.3715, respectively. The test temperature was kept at 22°C. The four parameters, , in Eq. WebBy expressing the relationships between individual properties: for example, the relationship between porosity and compressive strength for the prediction of compressive strength was defined by [3,33]. A reduction in the void ratio of the pervious concrete mixtures was found to result in an increase in the compressive strength [1,5].
