Dust of Alpilles

The stone quarry of Sarragan (Baux-de-Provence, Alpilles mountains) is the last underground stone extraction site of the Camargue region. From the extraction to the sawing and the cutting of the stone blocks, the quarry operations generate an important volume of dust (around 40% of the extracted stone).

The results show that in most of the plots the dust emission increases with the wind velocity. PM10 fluxes from the road surface in each plot were calculated to determine the effectiveness of the dust control products.

Introduction to Quarry

Quarry dust is a waste from the crushing unit which accounts 25%-30% of the final product from stone crushing unit and a reason to cause environmental pollution. Quarry dust can be used as an admixture in concrete efficiently to lessen its impact on environment and human. It can also be used as partial replacement of cement in concrete.

Stability of embankments constructed from soil

This study examines the stability of an embankment used in stone quarry reclamation built of local natural soil mixed with stone dust. Stone dust is a fine-grained and low-strength material, whereas soil is coarser with higher strength. Test results show that the shear strength and maximum dry unit weight of the mixed material increase with a decrease in the stone dust.
