“…Furthermore, as other researchers conclude (Aliabdo et al, 2014); (Miličević et al, 2015) (Sadek, 2012), the addition of ceramic recycled aggregates of CDW affects the mechanical strength of the blocks, in that they significantly reduce and limit the use of the designed product to that of non-bearing blocks. Furthermore, with the addition of these ceramic aggregates, then the water absorption is increased; when EPS is added to the samples, the water absorption remains similar to that of traditional products: almost identical to the degree of water absorption of a common brick.…”

“…In this context, many researchers have studied the behaviour of new materials that employ recycled aggregates from different origins as their raw materials. Among these studies, there are those which, in a cement matrix, incorporate recycled aggregates from: brick dust and ceramic tiles (Aliabdo, Abd-Elmoaty, & Hassan, 2014) (Miličević, Bjegović, & Siddique, 2015) (Sadek, 2012); ashes from thermal plants (Alba, Marrero, Leiva, Montes, & Vilches, 2012); EVA waste (footwear) (De Melo & Silva, 2013); the incorporation of waste in order to produce structural concrete (Valdés et al, 2010); and others that even produce new mortars with similar properties to traditional materials (Díaz, 2016);(Cabrera-Covarrubias, Gómez-Soberón, Almaral-Sánchez, Arredondo-Rea & CorralHiguera, 2015).…”

ResumenEste artículo presenta los resultados de una caracterización experimental de las propiedades físicas y mecánicas de un compuesto en base cemento que incluye áridos finos cerámicos y EPS reciclados para distintas dosificaciones procedentes de obras de rehabilitación. El objetivo es proponer un nuevo material de construcción desarrollado en Argentina para una posterior adaptación del mismo a la normativa española y europea para minimizar el impacto ambiental, mejorar la eficiencia energética y los costes de la ejecución, así como una solución al problema de gestión que suponen los residuos. Los resultados de los ensayos realizados muestran que al incrementar la cantidad de áridos y EPS reciclados, la resistencia mecánica se reduce frente a las muestras de referencia tradicionales. Al añadir EPS, se observa que se produce una disminución proporcional de la conductividad térmica, mejorando por tanto, las propiedades térmicas. Además, se obtiene que el grado de absorción del agua es similar al de las muestras de referencia y, frente al fuego, tienen un comportamiento también equivalente a éstas, obteniéndose que el nuevo material tiene baja emisión de humos y baja propagación de la llama. Palabras clave: Árido fino reciclado, materiales de construcción, sostenibilidad, residuos de construcción y demolición, poliestireno. AbstractThis article presents the results of an experimental characterisation of the physical and mechanical properties of a cement-based compound that includes recycled fine ceramic aggregates and EPS for various dosages from rehabilitation work. The aim of this research is to propose a new construction material, developed in Argentina, for its future adaptation to Spanish and European regulations in order to minimise the environmental impact, improve energy efficiency and reduce construction costs, as well as provide a solution to the problem that CDW (Construction and demolition waste) management represents. Tests results show that when increasing the amount of recycled fine aggregates and EPS, the mechanical resistance is reduced in comparison with traditional sample products. By adding recycled EPS, it is observed that a proportional reduction of the thermal conductivity occurs, thereby improving its thermal properties. Furthermore, it is found that the degree of water absorption is similar to that of the reference samples, and fire tests show that its behaviour is also equivalent, thereby showing that this new material has low smoke emission and low flame spread.

“…Apesar da adição de argila e similares ao concreto não ser consensual, há embasamento técnico que justifique a tentativa. A substituição de até 25% do agregado fino por tijolo em pó não causaria perda tão relevante na resistência à compressão do concreto, como observado por Aliabdo, Abd-Elmoaty e Hassan [4], diferentemente do que ocorre com a substituição do agregado graúdo [5]. Além disso, há diminuição de 8 a 17% em sua densidade, conforme Kesegić, Netinger e Bjegović [6], fator crucial para uma telha de concreto, as quais são associadas ao alto peso.…”

Resumo: Na construção civil, sempre são gerados detritos, um material descartado ainda com potencial de ser reciclado. Este projeto visa a síntese de uma telha utilizando detritos de construção, um item versátil que dá aplicabilidade ao entulho da construção civil. Na primeira fase, foram montados três protótipos de telhas, com a substituição integral do agregado graúdo pelos detritos. Concreto, tijolo e cerâmica moídos foram utilizados no lugar da brita. O molde foi feito reutilizando telhas de concreto e uma cobertura em plástico. A partir dos testes nota-se a necessidade de se melhor quantificar as propriedades do concreto reciclado. Baseando-se nisso, e no estudo bibliográfico subsequente, decidiu-se reavaliar as proporções e as misturas de concreto. Foram preparados noventa corpos de prova, três para cada uma das trinta misturas. Para agregado fino, foram utilizadas diferentes proporções de emboço, tijolo moído e areia. Como agregado graúdo foi usado concreto e cerâmica, além da brita, também em variadas proporções. Ao término da cura, os corpos foram movidos até uma prensa hidráulica, onde foram submetidos a testes de força na compressão e na tração de flexão. Das trinta misturas feitas, cinco apresentaram resultados comparáveis ao grupo controle. Para futuros testes, recomendam-se as duas misturas de melhor resultado, com uso parcial do emboço, cerâmica e concreto reciclado. Se utilizadas as devidas proporções, a reciclagem do concreto não só é viável, como é ecológica. Palavras-chaves:Telha; Concreto; Cerâmica; Reciclagem; Agregado fino e graúdo. Abstract:In civil construction, there will always be debris, a waste product with plenty potential to be reused. This project aims the development of a concrete roof tile, using construction debris, a versatile item which gives a destination to civil construction rubble. In the first phase, three prototypes were assembled, with complete coarse aggregate substitution by the debris. Crushed concrete, brick and ceramic were used to replace stone. The mold was made reusing concrete roof tiles and a plastic cover. Based on results, it was stated the need for a better quantification of the recycled concrete properties. That considered, and the additional bibliographic research, the concrete proportions and mixtures were reevaluated. As fine aggregate, different mortar, brick and sand proportions were used. As coarse aggregate, besides stone, concrete and ceramic were used, also in different proportions. By the end of the cure, the test bodies were moved to a hydraulic press, where they were tested for compression and flexural strength. Five of the original thirty mixtures had a reasonable result when compared to the control group. For future tests, the best two mixtures, with partial use of mortar, ceramic and concrete recycled are recomended. If made with the right proportions, concrete recycling is not just viable, but ecologic.

Asphalt industry finds itself battling ongoing economic difficulties and an urge to achieve a more sustainable development and growth. it means constant searching is needed for alternative materials and possibilities to use recycled and processed waste materials in asphalt mixes as long as an expected level of performance and durability is provided. Aluminium dross is a recyclable by-product of the casting process of melted aluminium. in this study an attempt was made to reveal the potentials of using aluminium dross as filler for asphalt wearing course mixes. During the research, filler fractions (d<0.063 mm) were prepared by milling and microstructural tests were conducted both on the alternative and control filler for a better understanding of the materials and their composition. the effect of replacing limestone filler with aluminium dross filler on the performance of asphalt mixes was analysed by performance-based and performance related asphalt mechanical tests according to common standards. in the paper, the properties of fillers and various mechanical test results are presented and by interpreting the tests and results final conclusions are presented regarding the use of aluminium dross as filler in asphalt mixes. keywords: asphalt, aluminium dross, filler, rheology, stiffness kulcsszavak: aszfalt, alumínium salak, töltőanyag, reológia, merevség member of the member of the Hungarian scientific Association for transport bella UDvarDi, bSc Graduated in 2017 as material engineer, Bsc. currently working on her msc diploma work.
