Dec 18, 2017 This research investigated the potential of cement stabilized shale quarry dust for possible use as road foundation material. From the results, the shale consists mainly of SiO 2 (27.7–60.1%), Al 2 O 3 (7.30–17.9%), CaO (3.91–32.3%) and LOI (4.93–18.8%). The shale quarry dust (SQD) in its natural state had an average liquid limit (LL) as 38%, plasticity index (PI) as 24% and

found that the compressive and flexural strength of concrete made of Quarry Rock Dust are nearly 10% more than the conventional concrete (Suribabu et al., 2015). In the present study it is proposed to investigate the optimum replacement of river sand with stone dust for concrete in term of compressive strength performance at 7 days and 28 days. II.

Crusher stone dust can be an economic alternative to the river sand. Crusher stone dust is produced during crushing of stones into aggregates of desired size say 10mm, 20mm etc. These dusts are generally used in making blocks or land filling. It has potential to be used as partial replacement of natural river sand in concrete.

If the 'good stuff' is all used up first, it may be more difficult to make cement out of what is left. Careful selection on a day-to-day basis is needed to make the best use of all the materials available. Raw materials are extracted from the quarry, then crushed and ground as necessary to provide a fine material for blending.
