  • ACARP Abstract

    Stone dust tends to fall out earlier than coal dust due to its coarser size and higher density This causes the incombustible content to rise away from the duster Almost all of the stone dust distributed by the trickle duster was seen to fallout within 100 to 150m of the sourceClayey soils are commonly stiff in dry state but lose their stiffness when saturated with water Soft clays are characterized by low bearing capacity and high compressibility In this research, stone dust obtained from stone processing area used for Stabilization of clayey soil with lime Thus, the effectiveness of using stone powder and lime in stabilizing finegrained clayey soil (CL) wasEffect of Stone dust and Lime in the GeotechnicalThe stone dust (limestone) is raised into suspension along with the coal dust in an explosion and blocks the transfer of heat from one particle to another The practice of applying stone dust is known as stone dusting Recent research has shown that legislative requirements for incombustible material in the practice of stone dusting to suppressACARP Abstract

  • Use of Stone Dust in the Design of High Performance

    Stone dust is classified as material obtained from stone crushing process, and due to its fines rarely used in concrete design because of high water cement ratio requirement (Adis, 1991) [5] Kiliswa (2012), [6] studied the effect of quarry dust on the strengths and permeability of concrete (Class 20 and 25) From his results he concludedAbstract: Soil stabilization is the alteration of soil properties to improve the engineering performance of soils The properties most often altered are density, water content, plasticity and strength The primary reason fly ash is used in soil stabilization applications is to improve the compressive and shearing strength of soils The performance of fly ash and stone dust was studied byAbstract: Stabilization of Expansive Soil by Fly Ash andAbstract: The present study deals with the emissions of the suspended particulates (silica dust) from stone crushing industry and its effect on workers and nearby residents A detailed air pollution survey was conducted at Chitrakoot, Banda and Mahoba of Bundelkhand, U P India High volume and respirable particulate samplers were used atAbstract of Effect of Particulate Matter on Stone Crushing Sit

  • Role of 'dusting and popdusting' using a highpowered

    Abstract Ureteroscopy and laser stone fragmentation (URSL) has had recent advancements with the more powerful laser systems with the ability to 'dust' and 'popdust' the stone We wanted to look at the outcomes of this method for large stones (≥ 15 mm) using our new 100 W holmium laser Over a period of 16 months (January 2017April 2018), 1029Abstract Occupational exposure to silica occurs at workplaces in factories like quartz crushing facilities (silica flour milling), agate, ceramic, slate pencil, glass, stone quarries and mines, etc, Nonoccupational exposure to silica dust can be from industrial sources in the vicinity of the industry as well as nonindustrial sourcesNonoccupational exposure to silica dustAbstract Stones are naturally occurring rocks of igneous, sedimentary or metamorphic origin Most of the rocks are sufficiently consolidated to enable them to be cut or made into various shapes(PDF) PROPERTIES OF BUILDING STONES ResearchGate

  • Effect of Stone dust and Lime in the Geotechnical

    Clayey soils are commonly stiff in dry state but lose their stiffness when saturated with water Soft clays are characterized by low bearing capacity and high compressibility In this research, stone dust obtained from stone processing area used for Stabilization of clayey soil with lime Thus, the effectiveness of using stone powder and lime in stabilizing finegrained clayey soil (CL) wasThe manufacture of kitchen and bath countertops in Israel is based mainly on artificial stone that contains 93% silica as natural quartz, and ∼3500 workers are involved in cutting and processing it Artificial stone produces high concentrations of silica dustArtificial stone dustinduced functional and inflammatoryThe airborne concentrations of stone dust generated were higher when cutting than polishing for any specific stone, even after taking into account the different dust tunnel speeds The concentration of respirable emissions as a percentage of inhalable dust ranged between 8 and 13% when cutting and 16–32% when polishingCharacterizing and Comparing Emissions of Dust,

  • Artificial stone silicosis : Current Opinion in Allergy

    is now commonly used for the production of kitchen benchtops Reports of artificial stone silicosis from many countries have noted that workers were typically employed at small workplaces and were often diagnosed in their 30s or 40s Poor exposure control measures were common, including the practice of ‘dry processing’ Dust generated from artificial stone has been noted to have propertiesAbstract Objectives: Workers who fabricate stone countertops using hand tools are at risk of silicosis from overexposure to respirable crystalline silica This study explored the efficacy of simple engineering controls that can be used for dust suppression during use of hand tools by stone countertop fabricators in bulk dust samples fromExperimental Evaluation of Respirable Dust and CrystallineAbstract Occupational exposure to silica occurs at workplaces in factories like quartz crushing facilities (silica flour milling), agate, ceramic, slate pencil, glass, stone quarries and mines, etc, Nonoccupational exposure to silica dust can be from industrial sources in the vicinity of the industry as well as nonindustrial sourcesNonoccupational exposure to silica dust
