No you cannot compact sharp sand
Sharp sand feels sharp to the touch and is a much coarser material than lawn sand which is often called soft sand or builder's sand. If you want to lay bricks, soft sand is much easier to work with and to smooth down.
4" or 102 mm of compacted sand or gravel fill.
exfoilation
Presence of sand dunes and compacted ergs in arid/desert regions and occurence of deposited weathered regoliths at footslopes/basements of rocks in temperate and tropical areas.
Sand is a solid, it comes from the three types of minerals: metamorphic, sedimentary, and igneous. When one of these rocks have contact with erosion or wind, over a period of time it will break down into sediments. The sediments can be sand, silt, clay, and other things. Soon the sediments will get compacted back together again and this part of the rock cycle starts over again.
In compacted sand the grains of sand are closer together, meaning there are more grains in a certain volume. This gives a higher value for density.
a lot of sand compacted into layers
(Some where) 1 tone sharp sand = .7 M3 (Some where) 1 tone sharp sand dry = 1.60 M3 1 tone sharp Sand, wet - 1.92 M3 1 tone sharp sand loose = 1.44 M3 Iftikhar khan
The sand would need to be compacted and cemented together by precipitated minerals over time.
Sharp sand is used in construction. It is a material that is mixed with concrete or soil and the sand is substantially free of bond. It does not refer to the grain shape of the sand.

When molten rock breaks through sedimentary (compacted sand) rock
Sand is a natural earth material and as such can be somewhat variable depending on the composition of the clasts and the degree of compaction. However see below: Sand (dry) - 1.6 tonnes/m3 Sand (loose / poorly compacted) - 1.44 tonnes/m3 Sand (well compacted) - 1.680 tonnes/m3 Sand (wet) - 1.92 tonnes/m3 Sand (wet, packed) - 2.08 tonnes/m3

Sandstone
Light-colored sand is mostly quartz. The specific gravity of quartz is 2.65, but sand is porous. A good approximation is 1.6 for compacted sand where the interstitial volume is filled with air, rising to 1.9 when the sand is saturated with water.
as at Nov 2011 prices of sharp sand in Nigeria around Lekki Ajah Axis is between 2400 to 2600
