The particle size distribution was calculated by means of the ImageJ software version 1.50i, using the B1, B2 and B3 micrographs obtained with the Scanning Electron Microscope, as a result: 5% of the particles had a size greater than 10μm (> PM 10 ) on average, 39% of the particles had sizes between 2.5μm - 10μm (PM 10 - 2.5 ) on average and 56% of particles had sizes smaller than 2.5μm (<PM 2.5 ), these particles <PM 2.5 being the most harmful to health and are associated with diseases such as pneumonia, asthma and child bronchitis. The particles are composed of: O, Ca, Mg, Na, Si, S, Fe, Ti, K, Al; these chemical elements are characteristic of the crystalline phases of each cement manufacturing process, while the elements: Pu, Zn, Cl are present in the side that was next to the ceiling, since these are covered by an alloy of 55% of Al and 43% of Zn. 2017 artículo científico 0250-5460 https://www.redalyc.org/articulo.oa?id=426352861002 es http://www.redalyc.org/revista.oa?id=4263 Revista Boliviana de Química application/pdf Universidad Mayor de San Andrés Revista Boliviana de Química (Estado Plurinacional de Bolivia) Num.3 Vol.34 |
