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 … WebPorosity (n) is defined as the ratio of the volume of voids to the total volume, or 𝑛= (3.4) The degree of saturation (S) is defined as the ratio of the volume of water to the volume of voids, or 𝑆= (3.5) It is commonly expressed as a percentage. The relationship between void ratio and porosity can be derived from Eqs.
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. 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].
Webconditions. A combination of the two sets of equations relates porosity to void ratio and relates the modulus of elasticity to the coefficient of compressibility, coefficient of volume compressibility, compression index, coefficient of consolidation, specific storage, and ultimate compaction. WebJul 9, 2024 · Porosity, the percent by volume of a soil sample not occupied by solids, is directly related to bulk density and particle density. If particle density remains constant, as bulk density increases porosity decreases.
