“…This behavior could be explained by the low density of the CA compared with the NA (see Table 1), which also has been reported in previous studies (Jiménez et al, 2013;J. Silva, Brito, & Veiga, 2010;M. A. G. Silva, Silva, & Simão, 2007).…”

Revista de la Construcción Journal of Construction 22] Mechanical properties of mortars containing recycled ceramic as a fine aggregate replacement Propiedades mecánicas de morteros que contienen cerámica reciclada como reemplazo del árido fino Abstract We study the behavior of mortars where 0%, 10%, 20%, 30%, 50% and 100% of their original natural sand was replaced by ceramic sand in a search of potential new building materials that will help to conserve natural resources and that are environmentally friendly. In this paper, the physical properties of the sands and their derived mortars, including their compressive strength, flexural strength, and shrinkage due to base and total drying, are characterized. Our results show that the compressive and flexural strengths of the recycled mortars decrease proportionally to the amount of natural sand replacement used. A similar behavior is observed for the shrinkage due to drying in mortars with low ceramic substitutions (10%, 20% and 30%). Based on these findings, we believe that the use of mortars made with recycled sand (with substitution contents lower than 30%) could be feasible in applications where the mechanical requirements are low. Resumen A partir de la búsqueda de nuevas alternativas en el área de construcción que ayuden a la conservación de los recursos naturales y del medio ambiente, se estudia el comportamiento de morteros con sustituciones parciales de reemplazo del 0%, 10%, 20%, 30%, 50% y 100% de arena cerámica reciclada por arena natural. Se caracterizan las propiedades físicas de las arenas estudiadas, así como las propiedades mecánicas de los morteros resultantes de ellas; tales como la resistencia a la compresión, flexión y de retracción básica, por secado y total. Los resultados obtenidos indican que para la resistencia a compresión y a flexión de los morteros reciclados, éstos sufren decrementos proporcionales al remplazo de la arena natural; sin embargo, para el caso de la retracción por secado éstos reportan comportamiento similar (morteros con sustituciones bajas de 10%, 20% y 30%). En base a lo anterior, morteros con arena cerámica reciclada (con contenidos menores al 30% de reemplazo) podrían ser factibles de su utilización en aplicaciones, en las cuales los requerimientos de éstos sean bajos.

“…High strength to weight ratio, fast curing time, very low permeability, enhanced impact and damping behaviour and high resistance to chemical, weathering agents and frost attack are some of the enhanced properties of this class of materials over conventional cement based concretes (Fowler, 1999;Ribeiro et al, 2002Ribeiro et al, , 2004Ribeiro et al, , 2009. As drawbacks, the relative high cost, the high sensitivity to creep and to elevated temperatures, the deficient behaviour under fire and the relative high coefficient of thermal expansion and shrinkage have been reported (Fowler, 1999;Marín et al, 2003;Ribeiro et al, 2003aRibeiro et al, , 2004Silva et al, 2007;Tavares et al, 2002). Nevertheless, currently, one of the main assets of PC materials is their great ability for incorporating recycled wastes, mainly due to the hermetic nature of the resin matrix (Bignozzi et al, 2000;Garbacz and Sokolowska, 2013;Nóvoa et al, 2004).…”

“…It is the durability and resistance against corrosion of construction materials that are the characteristics considered in recent years as the chief aim of the research into the process of modifying the existing materials and/or producing new composites of improved properties. Numerous research institutions have been conducting long-term research into the fabrication of new polymer concretes that can be successfully used for protecting structures against the harmful influence of aggressive agents [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20].…”
