Abstract This experimental study presents the variation in the strength of concrete when replacing sand by quarry dust from 0% to in steps of 10%. M20 and M25 grades of concrete were taken for study keeping a constant slump of 60mm. The compressive strength of concrete cubes at the age of 7 and 28 days were obtained at room temperature.

between these health endpoints and exposure to respirable dust in this sample of stonecrushers. Methods This was primarly a crosssectional descriptive study with analytic components. This study analysed a subset of data collected in a health survey of stone crushers in Kigamboni informal stone quarry in DaresSalaam, Tanzania in 2007.
concrete production is required and quarry rock dust which has the physical and chemical properties almost similar to the natural sand could be the alternative. This study mainly focus on the mechanical properties of eggshell concrete with quarry rock dust compare to normal eggshell concrete. Besides that, the optimum percentage of quarry rock dust
· Portland limestone cement, river sand and quarry rock dust both of 2 mm maximum size as fine aggregate, and 14 mm crushed rock coarse aggregate were used for the concrete The particle size distribution and the physical properties of the fine and coarse aggregates are shown in Fig. 1 and Table 1 respectively. The fine and coarse aggregates satisfied the BS EN 12620:2002 + A1:2008 .
