In order to ensure the aggregate performs as intended for the specific use, a variety of tests must be performed on the aggregate One such test is determining materials finer than No 200 (75 µm) sieve in mineral aggregates by washing Fine materials such as clay particles or water soluble particles removed by washing, can cling to larger .
11 This test method describes the procedures for measuring in-place density and moisture of soil and soil-aggregate by use of nuclear equipment (hereafter referred to as “gauge”) The density of the material may be measured by direct transmission, backscatter, or backscatter/air-gap ratio methods
* The bulk density is the mass of the material related to a specific volume and for cement is normally expressed as “kilograms per cubic metre” * The bulk density reflects the volume taken up by the cement plus any air trapped between the p.
