Diseño de mezclas de hormigón reciclado mediante el método Volumen de Mortero Equivalente (EMV): Validación bajo el contexto español y su adaptación al método de diseño de Bolomey

Abstract: A new method for proportioning recycled aggregates concrete (RAC) is used to check its feasibility under the Spanish context. First, an extensive experimental campaign has been done, with the purpose of check and analyze the applicability of the EMV method with two Spanish recycled concrete aggregates (RCA). The aim of the second part of the investigation, was to elaborate an adaptation of the EMV method to Bolomey methodology (1), using a 20% weight replacement of coarse natural aggregates (NA) for RCA, and s… Show more

“…Concrete mixes components were a CEM I 42.5 R cement from CEMEX Co., two calcareous sands (I and II) and one calcareous coarse aggregate, and two RCA. The aggregates grading curves were presented in a previous investigation (6). RCA type A, was obtained by crushing old concrete specimens and its composition consisted of 89% of NA with attached mortar and 11% of clean NA.…”

“…Along the whole investigation, several characteristics of the concrete were studied, starting from the fresh concrete properties such as slump ( 9), air content and fresh densities (10); followed by hardened concrete properties such as hardened densities (11), compressive strength (12) and static modulus of elasticity (13); and finally some durability properties. On this part of the investigation only the durability properties of the concrete will be addressed because all the other properties have been already published (6), and they will be mentioned purely for information purposes.…”

“…Choque térmico: Consiste en someter una muestra de agregado, previamente saturado, a elevada temperatura durante un determinado tiempo (entre 30 minutos y 1 hora), lo cual crea tensiones en el interior de las partículas del agregado debido a la rápida evaporación del agua. En tal sentido, diversas temperaturas han sido consideradas para esta metodología: Jiménez et al (2013) propone 500°C, mientras que otros autores consideran más adecuado temperaturas en torno a 300°C (Sui y Muller, 2012). Luego, el AR caliente es introducido en agua fría, provocando la separación del mortero del agregado natural.…”
