“…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.…”

“…As stated in [8], roof tiles ceramic samples containing residues from granite cutting/polishing and silica sand washing indicate a beneficial effect of waste on ceramic body's properties, reducing water absorption and increasing flexural strength for mixtures containing both wastes. Torres et al [7] published results indicating that porcelain tile samples containing 20% to 40 wt% of granite cutting sludge and fired in industrial furnace at 1210 ºC present similar flexural strength values when compared to mixtures without granite cutting residue. Albite phase was also identified by X-ray diffraction for mixtures containing granite as raw material.…”

“…A indústria de rochas ornamentais gera muita riqueza e desenvolvimento social no país com a criação de milhares de empregos diretos e indiretos. Por outro lado, a indústria de rochas ornamentais também gera enormes quantidades de resíduos sólidos poluentes [7][8][9]. Estes resíduos sólidos na maioria das vezes, principalmente no Brasil, são dispostos inadequadamente no meio ambiente, o qual resulta em poluição ambiental de difícil solução.…”

“…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.…”

“…Diversos trabalhos têm sido relatados na literatura sobre a incorporação de resíduos de rochas ornamentais em materiais cerâmicos para a construção civil. [7][8][9][10][11] Em geral estes resíduos apresentam composições química e mineralógica que, quando adicionados às formulações cerâmicas em quantidades adequadas, favorecem o processamento cerâmico. Os resíduos de rochas ornamentais são ricos em compostos fundentes (K 2 O e Na 2 O) que auxiliam na formação de uma fase vítrea durante o processo de sinterização.…”
