Abstract
Some durability properties are analyzed in concretes made with a novel method for recycled aggregates concrete (RAC) proportioning, in order to validate it under the Spanish context. Two types of concrete mixes were elaborated; one following the guidelines of the named method, and other based on an adaptation of the method to Bolomey methodology. Two types of recycled concrete aggregates (RCA) were used. RCA replacement for natural aggregates (NA) ranged from 20% to 100%. The 20% was chosen in order to comply with Spanish recommendations. Water penetration under pressure, water absorption and chlorides attack were the studied properties. It is verified that the new method and the developed adaptation results in concrete mixes of better or similar properties to those of the natural aggregates concrete (NAC) and the conventional RAC, saving important amounts of cement. //
Algunas propiedades de durabilidad son analizadas en hormigones elaborados con el nuevo método para la dosificación de hormigones con árido reciclado (HAR) para validarlo bajo el contexto español. Se elaboraron dos tipos de hormigones; uno siguiendo las directrices del nuevo método y otro basado en una adaptación del anterior a la metodología Bolomey. Se utilizaron dos tipos de árido reciclado (ARH). Los reemplazos de áridos variaron entre 20% y 100%. El 20% ha sido elegido para cumplir con recomendaciones españolas sobre HAR. Las propiedades estudiadas fueron: penetración de agua bajo presión, absorción de agua y susceptibilidad al ataque de cloruros. Se verifica que el nuevo método y la adaptación desarrollada resultan en hormigones con mejores o similares características que las de un hormigón con áridos naturales (HAN) y las de HAR convencional, ahorrando, además, importantes cantidades de cemento.
