          Abstract

          This paper deals with the analysis of the generation of Construction and Demolition Waste (CDW) in Havana, Cuba, for the period 1999 to 2010 and its possible use in the manufacturing of recycled aggregates in mortar and concrete production. In order to define the possible applications of the CDW as aggregates in mortar and concrete production the characteristics of the waste as well as studying the existing technologies available in the province for their treatment were analysed. Based on the experimental results, it was determined that the recycled fine aggregates of a mixed composition achieved the minimum requirements defined by Cuban regulations. All the mortars produced with recycled fine aggregates achieved a compressive strength of 5.2 MPa after 28 days which is the minimum requirement for a Type III mortar, consequently they could be used in the manufacturing of masonry mortar. The recycled coarse aggregate originating from pre-cast floor elements could possibly be used in the production of structural concrete for medium and low aggressive environments when concretes were made with 50% and 100% of recycled coarse aggregates in substitution of the natural aggregates. respectively.

          En este trabajo se realiza un análisis de la generación de Residuos de Construcción y Demolición (RCD) para el período de 1999 a 2010 en La Habana, Cuba y se define su posible uso en la fabricación de áridos reciclados para la producción de mortero y hormigón. Para la definición de las posibles aplicaciones de los RCD como agregados en la producción de mortero y hormigón, se analizaron las características de los residuos, así como el estudio de las tecnologías disponibles actualmente en la provincia para su tratamiento. Basado en los resultados experimentales, se determinó que los áridos finos reciclados de composición mixta cumplían con los mínimos requisitos exigido por las normas cubanas. Todos los morteros producidos con áridos reciclados finos obtuvieron una resistencia a compresión de 5.2 MPa a los 28 días, que es el mínimo establecido para morteros tipo III, por lo que pueden ser utilizados en la producción de morteros de albañilería. El árido grueso reciclado originado de elementos de hormigón prefabricado puede ser utilizado en la producción de hormigón estructural para ambientes de baja y media agresividad, con sustituciones de 50% y 100%, respectivamente, de árido natural por reciclado.
