Abstract/Contents: | "The bulk density of compressible materials depends on the compressive load to which they are subjected. This results in bulk density variation within piles of such materials. However, it is difficult to measure bulk density in situ without disturbing the sample or changing the load on it. A laboratory method was developed to simulate the variation of density with depth of material. The method was used with compost, wood shavings, straw and peat and simulated material depths of up to 3.5 meters. The variation of bulk density with depth was shown to follow a power function relationship where the exponent provided an indication of the compressibility of a material. Effective density is proposed as a useful single descriptor of bulk density. Both effective density and material compressibility were shown to be influenced by the size of container used to obtain measurements. A medium sized container (400-mm diameter and 380-mm fill height) provided a good compromise between accuracy and practicality." |
