154 AGGREGATE SUBGRADE THICKNESS DETERMINATION
2) Aggregate layer compaction; and 3) Loading. Specifically, a crushed limestone having low plasticity fines and compacted to 95% of the maximum laboratory density was identified as a best practice and can be used at thicknesses less than the current design recommendations. However, uncrushed gravel and reclaimed asphalt pavement performed poorly.
Replacement of sand with 30%, 50%, and 70% of PVC aggregates led to reductions in dry density of up to 12%, 18%, and 27%, respectively. For fresh concrete the density reductions were 5.5%, 11%, and 22.5%. One can observe that there is some effect of concrete curing on the residual density, especially at low PVC aggregate content.

Density of Cement Sand and Aggregate in Kg/m3 | list of ...
Cement density:- generally density of cement is around 1440kg/m3 or it is measured in other unit- their density is 1.440 in g/cm3, 94 in lb/ft3 and 14.40 in kn/m3. The cement mixed with fine aggregate produces cement mortar for masonry, or with sand and gravel produces concrete. Ans. 1440 kg/m3 is density of cement.
It also seems that the particle''s angularity has a strong influence on packing density: de Larrard (1999) reported that rounded aggregates give a packing density close to 0.60 while crushed aggregates packing gives values between 0.50 and 0.57. Such results suggest that packing density can be related to a ''roundness'' factor and some attempts to do this have been described in the ...
Aggregates for Concrete
Crushed stone is produced by crushing quarry rock, boul-ders, cobbles, or large-size gravel. Crushed air-cooled blast-furnace slag is also used as fine or coarse aggregate. The aggregates are usually washed and graded at the pit or plant. Some variation in the type, quality, cleanli-ness, grading, moisture content, and other properties is expected.
