Sales Inquiry Effect Of Cement Dust On Machineries. Effect of replacement of natural sand by manufactured sand . for concrete. Ilangovan et al., 2006: studies the strength and behavior of concrete by using crushed rock dust as fine aggregate, they investigated the possibility of using crushed rock as 100 % replacement for sand, with varying compacting factors.
cement factory management embark on health education of workers, acquire effective protective gadgets and enforce their usage. These measures would help to decrease the effects of occupational hazards of cement dust and detect the disease in initial stage when treatment is achievable in cement
#0183;#32;After water, concrete is the most widely used substance on the planet. But its benefits mask enormous dangers to the planet, to human health and to culture itself
#0183;#32;Few studies have been carried out on acute effects of cement dust exposure. This study is conducted to investigate the associations between current quot;totalquot; dust exposure and acute respiratory symptoms and respiratory function among cement factory workers. A combined crosssectional and crossshift study was conducted in Dire Dawa cement factory in Ethiopia. 40 exposed production
ENVIRONMENTAL IMPACTS OF CEMENT PRODUCTION
However, collective effort describing the general effects of cement dust on different organ and systems in humans or animals, or both has not been published. Therefore, the aim of this review is to gather the potential toxic effects of cement dust and to minimize the health risks in cement mill workers by providing them with information regarding the hazards of cement dust.
Effect of cement dust on chlorophyll was studied in Arachis hypogaea, Sesamum indicum and Triticum species. Sampling was done at different distance like km, km and km from the cement
The Effect of Cement Dust on the Lung Function in a Cement . potential adverse effects on the respiratory system [ 9 11 ] also Portland cement dust is considered to have little potential to induce adverse effects on the lung such as pneumoconiosis or fibrosis [ 12 13 ] However Mwaiselage et al (2005) showed a significant relationship between cumulative cement dust
Cement dust is a potentially phytotoxic pollutant. Large amounts of toxic substances are emitted during its production viz. carbon dioxide, particulate matter (dust), oxides of nitrogen and sulfur dioxide. Cement dust also contains heavy metals like
