Porosity void ratio relationship
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]. WebRather, the ratio of void space to total volume (i.e. porosity) does not change with scale (given that the packing of the grains does not change). It is shown in Figure 2 that two systems of different scale have the same porosity. Therefore, for a given geometry, porosity is independentof grain size. 2r 1 2r 2= 4r 1 4r 14r 1= 8r
