“…Clay-based ceramics, such as bricks, are heterogeneous materials, which can incorporate raw materials of wide ranging compositions, without impairing their technical properties (Dondi et al, 1997;Segadães et al, 2005;Torres et al, 2009;Zhang, 2013). Due to this ability, bricks have become a popular material in waste management research worldwide and several studies have demonstrated that clay-based bricks and tiles can successfully accommodate waste types, such as incineration ashes, mine tailings and dredged harbour sediments (Chen et al, 2011;Kasuriya et al, 2008;Mezencevova et al, 2012;Roy et al, 2007;Zhang et al, 2011).…”

“…Due to serious environmental hazards, such as heavy metal pollution, the tailings disposals often need continuous surveillance even after the mining operations have terminated (Elberling et al, 2002;Ramirez-Llodra et al, 2015). Several authors have investigated the potential for using residues from the mineral resource industry as secondary raw materials for the production of clay-based ceramics (Chen et al, 2011;Menezes et al, 2005;Roy et al, 2007;Segadães et al, 2005;Torres et al, 2009). Benefits such as increased durability (Torres et al, 2009), reduced firing temperature (Segadães et al, 2005) and lowered total cost (Roy et al, 2007) were reported for the produced ceramics.…”

The Arctic area contains several mining operations and has already experienced severe environmental problems relating to tailings (Askaer et al, 2008;Poland et al, 2003) Up until this date, only a few mines have been in operation in Greenland, but serious environmental problems relating to the tailings from some of these mines have also been experienced here (Johansen and Asmund, 2001).…”

“…According to ANICER [1], more than 100 million tons have been processed, increasing the consumption of natural resources and fuel, and causing serious environmental impacts. As a consequence, in order to reduce non-renewable raw material consumption, many industrial wastes have been tested as raw material for ceramic mass formulations such as steel slag powders [2], galvanic solid waste [3], ceramic slurry waste [4], granite [5][6][7][8][9][10] and marble [11][12][13] waste powders, and sedimentary rock powders [14,15]. Results published in [2] show that in red ceramic formulations containing 2% to 10 wt% of steel slag waste as raw material, there was a decrease in flexural strength and water absorption when compared to the mixture without waste.…”

Nowadays, environmental codes restrict the emission of particulate matters, which result in these residues being collected by plant filters. This basaltic waste came from construction aggregate plants located in the Metropolitan Region of Londrina (State of Paraná, Brazil). Initially, the basaltic waste was submitted to sieving (< 75 mm) and the powder obtained was characterized in terms of density and particle size distribution. The plasticity of ceramic mass containing 0%, 10%, 20%, 30%, 40% and 50% of basaltic waste was measured by Atterberg method. The chemical composition of ceramic formulations containing 0% and 20% of basaltic waste was determined by X-ray fluorescence. The prismatic samples were molded by extrusion and fired at 850 °C. The specimens were also tested to determine density, water absorption, drying and firing shrinkages, flexural strength, and Young's modulus. Microstructure evaluation was conducted by scanning electron microscopy, X-ray diffraction, and mercury intrusion porosimetry. Basaltic powder has similar physical and chemical characteristics when compared to other raw materials, and contributes to ceramic processing by reducing drying and firing shrinkage. Mechanical performance of mixtures containing basaltic powder is equivalent to mixtures without waste. Microstructural aspects such as pore size distribution were modified by basaltic powder; albite phase related to basaltic powder was identified by X-ray diffraction.

“…A problemática dos resíduos sólidos é um dos grandes gargalos a ser enfrentado pela indústria de rochas ornamentais no século XXI. Trabalhos têm mostrado a possibilidade de reaproveitamento destes resíduos sólidos na fabricação de cerâmica vermelha e revestimentos cerâmicos para pisos [7,8,[11][12][13]. No entanto, estes resíduos têm sido pouco estudados como material filler em materiais cimentícios.…”

ResumoA utilização de agregados industrializados vem crescendo ao longo dos anos para atender a grande demanda da construção civil devido ao crescimento econômico do país. O objetivo deste trabalho foi utilizar o planejamento experimental em Rede Simplex para avaliar o efeito da adição do resíduo de rocha ornamental como filler na composição de misturas ternárias (brita 0, pó de pedra e resíduo), que levem a máxima compacidade (densidade seca aparente máxima). Foram tomados dezesseis pontos experimentais, cujos teores dos materiais utilizados variaram de 0 a 100%. O modelo em rede simplex cúbico completo apresentou melhor ajuste aos resultados experimentais, o qual resulta em respostas estatisticamente mais adequadas para as composições estudadas. A superfície de resposta gerada indicou que a densidade seca aparente máxima de 2,0 g/cm 3 foi obtida para a composição ternária: 63% de brita 0/17% de pó de pedra/20% de resíduo de rocha ornamental. Portanto, o uso de resíduo de rocha ornamental como filler em agregados para a construção civil pode ser uma alternativa viável para deposição final deste abundante resíduo de forma ambientalmente correta. Palavras-chave: resíduo de rocha, filler, planejamento experimental, simplex, agregado. Abstract The use of industrial aggregates has grown over the years to meet the great demand of the civil construction due to the country's economical growth. The aim of this work was to use the experimental design in Simplex Lattice to evaluate the effect of the addition of ornamental rock waste as filler in the composition of ternary mixtures (crushed rock 0, stone powder, rock waste), leading to maximum compaction (maximum apparent dry density
