Loss on ignition LOI is a test used in inorganic analytical chemistry and soil science particularly in the analysis of minerals and the chemical makeup of soil It consists of strongly heating a sample of the material at a specified temperature allowing volatile substances to escape until its mass ceases to change This may be done in air or in some other reactive or inert atmosphere
a Calculate the void ratio e Here unit weight of the soil is water content is w Substitute 0 098 for w for Now use the formula of dry unit weight Here specific gravity of soil solids is unit weight of wet soil is void ratio is e Substitute 2 69 for for 17 5 for Therefore void ratio e is
POROSITY AND BULK DENSITY OF SEDIMENTARY ROCKS By G EDWARD MANGER ABSTRACT More than 900 items of porosity and bulk density data for sedimentary rocks have been tabulated Most of the data are from the more accessible American British German and Swiss literature The number of porosity determinations per item ranges from 1 to 2 109
Unit weight of a soil mass is the ratio of the total weight of soil to the total volume of soil Unit Weight g is usually determined in the laboratory by measuring the weight and volume of a relatively undisturbed soil sample obtained from a brass ring Measuring unit weight of soil in the field may consist of a sand cone test rubber balloon or nuclear densiometer
Specific gravity is a dimensionless unit that defines the ratio between the density of a rock and the density of water at typically 4 Celsius Density is an important characteristic of a rock since this parameter helps to identify the rock type and its geologic structure To …
