Mechanical and Microstructural Characterization of Quarry Rock
The purpose of this research is to study the effects of quarry rock dust (QRD) and steel fibers (SF) inclusion on the fresh, mechanical, and microstructural properties of fly ash (FA) and ground granulated blast furnace slag (SG)-based geopolymer concrete (GPC) exposed to elevated temperatures. Such types of ternary mixes were Construction aggregates derived from primary resources either by crushing of sound rock masses (crushed stone aggregates) or from naturally occurring unbound clastic sediments (natural sand and gravel aggregates) make the most voluminous mineral raw material exploited by humans nowadays (Fookes 1991; Přikryl Geomaterials as construction aggregates: a state-of-the-art

Evaluation of blast efficiency in aggregate quarries: facts and
Quarry blasts and seismicity. Blast operation creates both elastic and inelastic deformation within the nearby rock mass. A seismic event is a rapid inelastic deformation that occurred within a specified volume of rock (Ma et al. 2015).Regulatory authorities usually monitor blasts in quarries on the scheduled date of the operations by The extraction of rock materials from the landscape is accompanied by severe influence on nature.

(PDF) Annual Consumption of Crushed Stone Aggregates in
The results showed that an average of 102,000 cubic meters of crushed stone aggregate is produced by each of the 178 registered quarries in Ghana per annum; and this constitutes a national averageAs a secondary material, quarry fines are a valuable material to be reused for many purposes in civil engineering projects. The aggregate source depletion, especially the lack of high quality aggregates as expected in the future, as well as the demand for a carbon-neutral society and circular economy, also promotes the high-volume utilization of Assessment for Sustainable Use of Quarry Fines as Pavement Construction

Self‐reported disease symptoms of stone quarry workers
Even though existing studies have looked at these phenomena separately, there exists a critical knowledge gap in understanding the joint effect of work‐post and PPE usage on self‐reported disease symptoms of stone quarry workers. Knowledge about the joint effect of work‐post and PPE usage is important for developing strategies relevantA great deal of engineering work was necessary to address each aspect of the quarry preparation. Among the plans was sealing two tunnels in the quarry, which allowed trucks to move rock from the fracture site to the quarry plant. The tunnels were plugged with reinforced concrete to avoid flooding the still-active section of the quarry.Quarry serves as flood water reservoir Pit & Quarry
