Analysis (density and porosity analysis) from sample 110717
| Method | density and porosity analysis |
| Person/Institution | Shogenova, Alla |
| Sample number | |
| Remarks | Density and porosity were determined using the water saturation method. For density measurements samples were dried at a temperature 100110 °C and the weight of dry samples (Pd) was determined. Then the samples were saturated with water for 7 days and after that weighed in air (Pw) and water (Pww). From the obtained measurements the following parameters were calculated: dry density = Pd/V = Pd/(Pw Pww), where V represents sample volume; wet density= Pw/(Pw Pww); grain density= Pd/(Pd Pww); effective porosity = (Pw Pd)/(Pw Pww).
