ResumenEn este trabajo se realiza un análisis del impacto ambiental producido por la utilización de morteros cuyo ligante son desechos de polvo de vidrio. Dentro del concepto de sostenibilidad, la ingeniería civil debe desarrollar su capacidad para utilizar materiales de construcción que reutilicen productos de desecho, cuyo destino final son vertederos controlados y por otra parte que minimicen el impacto negativo en el medio ambiente a la hora de su puesta en obra. Para este fin, se han realizado ensayos de filtración sobre probetas de morteros fabricados con residuos de polvo de vidrio como ligante para identificar la migración o emisión de elementos lixiviados. La realización de estos ensayos ha dado como resultado que el único elemento liberado en forma apreciable es el sodio (procedente fundamentalmente del vidrio). Todos los demás elementos son liberados en cantidades inferiores a un mg/l por lo que no representan peligro ambiental.Palabras clave: Lixiviados; mortero; polvo de vidrio; Ligante.
Environmental Viability Assessment of Using Mortar Containing Glass Powder in Soil Stabilization
AbstractThis paper presents the analysis of the environmental impact caused by the use of mortar whose binder is made with waste glass powder. Within the concept of sustainability, civil engineering should develop their ability to use building materials reusing waste products, whose final destination are controlled landfills and secondly to minimize the negative impact on the environment when they are put into work. To this end, tests have been conducted on specimen's filtration mortars containing waste glass powder as binder migration to identify potentially dangerous emission of harmful elements. The realization of these trials has resulted in that sodium is the only element liberated in detectable amounts (principally from the glass). All other elements are released in quantities lower than one mg/l, which represent no hazard to the environment.
Patients with HIV infection are getting older, with more comorbidities, with very frequent use of concomitant treatments, and high number of adverse effects. This requires a multidisciplinary approach and a coordinated effort within the Primary Care setting.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
