Practice problems: Porosity and bulk density

4. Calculate the bulk density of a rectangular soil sample with dimensions 12 cm by 6 cm by 4 cm, that is 15% moisture content and weighs 320 g. Vol. of soil = 12cm x 6cm x 4cm = 288cm 3 Oven dry wt. = 320/1.15 = 272g r b = 272/288 = 0.97g/cm 3 . 5. Calculate the oven dry weight of a 350 cm3 soil sample with a bulk density of 1.42 g/cm3.

2.7.1 Introduction Proportions

aggregate, on an oven-dry-rodded basis, is used per unit volume of concrete. Appropriate values for this aggregate volume are given in Table 5.4. It can be seen that, for equal workability, the volume of coarse aggregate in a unit volume of concrete is dependent only on its nominal maxim size and fineness modus of the fine aggregate.

Aug 03, 2018 The dry density or dry unit weight ?d is defined as the weight of solids ( ) per unit of total volume (V) of the soil mass. Thus, d. What is Saturated Density. When the soil mass is saturated, its bulk density is called the saturated density. Thus saturated density is the ratio of the total weight of a saturated soil sample ( ) to its total ...

Bulk density is equal to mass if the volume is unit. In the above definition, the volume contains both aggregates along with voids between aggregate particles. The approximate value of bulk density for aggregate usually used for normal-weight concrete varies between 1200-1750 Kg/m 3 or 75 to 110 lb/ft 3. Relative Density or Specific Gravity of ...

EN 206:2013+A1:2016 (2016) defines heavyweight concrete as having an oven dry density greater than 2600 kg/m 3. The density achieved will depend on the type of aggregate used. High-density aggregates generally consist of high-density minerals or rocks, or they are man-made materials, such as steel or iron.

The Australian Standard AS 2578.1-1998 ‘Concrete aggregates’ defines particle density as the mass of a quantity of oven dried particles divided by their saturated surface dried volume, and the bulk density, as the mass of a unit volume of oven dried aggregate. Bulk density is determined either as compacted or un-compacted.
