That is known as fine aggregate and it is normally is sand or crushed stone having size less than 9.5 mm in diameter. Different types of fine aggregates and their size. 1) stone dust -0.5 mm to 5 mm 2) coarse sand-0.5 to 2 mm 3) medium sand -0.25 to 0.5 mm 4) fine sand-0.06 to 0.25 mm 5) silt- 0.002 to 0.06 mm 6) clay – less than 0.002 mm

Fill sand is another common material that is used in construction projects. It is comprised of the finest particles or rocks that have been broken down and eroded over time. Fill sand has a very high compaction rating, but it is prone to shifting and displacement. Many people choose fill sand because it is attractive and affordable.
