Stone dust and sand, both commonly used construction materials, play a pivotal role in ensuring the structural integrity and longevity of buildings. Understanding the distinctions between these materials is crucial for builders and homeowners alike. Let's delve into the world of stone dust and sand to make informed decisions when …

Clearly, dust monitors can perform a vital role in helping to protect safety at working quarries. However, a TSI DTE was recently hired from Ashtead Technology to perform monitoring prior to the commencement of quarrying operations, so that baseline dust levels could be established for comparison once the quarry is operational.

Abstract: Quarry rock dust is investigated as fine aggregate in replacement with sand in cement concrete admixture, as the properties of the rock dust are suspected to be as good as sand.
