Porosity void ratio relationship
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.

Then divide both numerator and … WebJul 27, 2024 · Relation Between Porosity (n) and Void Ratio (e) -Soil Relation Between Porosity (n) & Void Ratio (e) By the definition of porosity, we have, n = Vv/V Where, Vv = Volume of voids in a given soil mass. V= Total volume of the soil mass = Volume of voids …
WebFeb 7, 2024 · The porosity of the concrete increases slightly with every 15% increase in RCA by an amount in the range of 8 to 16% due to the increased coarseness of aggregate in the mix and the lack of fine aggregates in the mix. This indicates that there is a direct relationship between RCA content and the void ratio of the produced porous concrete.
