 · concrete, brick, and mortar. When workers cut, grind, drill, or crush materials that contain crystalline silica, very small dust particles are created. These tiny particles (known as "respirable" particles) can travel deep into workers' lungs and cause silicosis, an incurable and sometimes deadly lung disease.


Concrete Compressive Strength Using River Sand and …

The compressive strength of concrete built with river sand and quarry dust as fine aggregate was examined in this study. Ordinary Portland cement (OPC) was blended with river sand and quarry dust at five levels, namely 10%, 20%, 30%, 40%, and 50%, by partially substituting OPC with river sand and quarry dust.
