Recycled Concrete - an overview ScienceDirect Topics

Wet density of concrete was varied between 3.1% and 14.8%, hardened density between 3.5% and 14.1%, and oven dry density between 7.1% and 13.6%. Reduction of the density of air-dried concrete was lower and found to be in the range of 1.1%–12%.

PROPERTIES OF RECYCLED AGGREGATE CONCRETE

2015-2-18  An increase in a share of recycled aggregate in total mass of the component aggregate reduces the bulk density of fresh concrete, where it was shown that the bulk density of the recycled aggregate con-crete was 5% to 10% lower than in the comparable natural aggregate concrete, while concretes made with the recycled coarse aggregate and natural fine aggregates had densities of 1% up to 5% lower than in the comparable natural aggregate concrete. In general, the values of bulk densities of the fresh concrete based on recycled

2009-4-20  The weight/density of 82 pcf could be accurate for that sample. Large (4" -6") pieces of concrete are generally cubical and angular. The in-place density depends on the size and shape of the individual particles. Large pieces with no fines will give you a very low density (pcf) unless you have the optimum amount of fines of the correct gradation.
