[36], the dry bulk density and apparent density of the three aggregates were determined, 网页The packing density of aggregate increased by 3.75%, 13.6% and 18.4% for natural aggregate and 14.86%, 19.5% and 27.7% for recycled concrete aggregate using the proportions obtained from MTM, JDD 网页What is coarse aggregate’s bulk density? The mass of aggregates required to fill a unit volume container after aggregates are batched is known as bulk density of aggregates. If a statement says “a coarse aggregate with a higher bulk density,” it means that few of the voids can be filled using fine aggregates and cement. 网页Calculate: The percentage of voids is calculated as follows Percentage of voids = [ (Gs ϒ)/Gs]*100 Where, Gs = Specific gravity of the aggregate ϒ = Bulk density in kg/litre 3.2.1 Procedure for Loose Bulk Density 1.
