Resumen
En el presente trabajo se hace una revisión bibliográfica de la literatura relacionada con los residuos de construcción demolición y posteriormente con la de áridos reciclados, de estos se analiza su clasificación, propiedades y la tecnología para su obtención. Se identifican las principales organizaciones internacionales que incluyen los áridos reciclados y qué requisitos tienen estas para la fabricación, tanto, de un hormigón estructural como no estructural. Se realiza una caracterización de las principales plantas en el territorio donde se justifica la necesidad de obtención de áridos reciclados en nuestro país.
Se efectúa un análisis de las principales normativas internacionales (Estados Unidos y España) sobre el empleo de áridos reciclados y se vincula con la normativa vigente en nuestro país donde se propone un programa general para permitir el empleo de áridos reciclados en la normativa cubana. Entre las conclusiones extraídas se destaca que la ausencia de la norma cubana de especificaciones para los áridos reciclados, limita su producción industrial en Cuba, por lo que La normativa española EHE-08 Instrucción de Hormigón Estructural puede ser, en parte, adoptada como norma nacional para utilizar los áridos reciclados en la construcción.
In this paper is carried out a literature review of documents related to demolition and construction wastes, and subsequently, to recycled aggregates, of which classification, properties and technology for their production are analyzed. Major international organizations including recycled aggregates are identified, and its requirements for manufacturing weather a structural or non-structural concrete. There is a characterization of the main plants in the territory where it is justified the need for obtaining recycled aggregates in our country. An analysis of the main international standards (U.S. and Spain) on the use of recycled aggregates is made and linked with the current standard in our country where a general program is proposed to allow the use of recycled aggregates in Cuban standard. Among the conclusions is highlighted that the absence of specifications regarding recycled aggregates in the Cuban standard, limits its industrial production in Cuba, therefore, the Spanish legislation EHE-08 Instruction of Structural Concrete can be partly adopted as a national standard to use recycled aggregates in construction.
