Assessment of Air Dust Content in the Production of the Reinforced Concrete Products


Annotation:

Globalization of the economy increases the burden on the environment, intensifying the antagonism between the nature and technology, generating environmental problems. Production increases the volume of use of the atmospheric air, and the parameters of dust formation determine the environmental risk to the enterprise employee health and the living matter of the environment.
Production of the reinforced concrete products is a source of the increased hazard for the employees and environmental ecosystems, supplying mobile fractions of the mineral particles into the atmosphere. Fine dust is considered the most dangerous.
An accurate assessment of air pollution is required as a basis for developing context-specific measures to ensure the safety of work and environmental ecosystems. Technical feasibility and environmental efficiency of the dust assessment with measurements in different places and at different times with air pumping through several alternative filters is substantiated. The main source of dust formation is vibration engineering. To isolate the most dangerous mobile dust fraction, it is advisable to use several filters made of various filter materials. The dust fraction content is defined as the ratio of the dust mass on the analytical filter to the sum of the particle masses on three filters.
The use of the recommended methodology will allow to reduce dust formation in the workplaces and pollution of the surrounding areas ecosystems. Parameters of the technogenic dustiness can be minimized by using the proposed methodology with the deposition of hazardous dust particles by a complex of filters made of the alternative filtering materials, for example, non-woven synthetic materials. Recommendations based on the results of the study may be in demand at the enterprises of various industries.
