“…Segundo pesquisa realizada pelo SINDICERAM (Sindicato das Indústrias de Cerâmica -Criciúma -SC) [6], em dezembro de 2015, o volume produzido de pisos foi de aproximadamente 6.600.000 m 2 e de azulejos foi de 2.000.000 m 2 na região de Criciúma, sendo, portanto, uma região ativa na geração de resíduos cerâmicos. Estes materiais são compostos principalmente por SiO 2 e Al 2 O 3 [7], o que indica a possibilidade de uso como material pozolânico. Desta forma, o objetivo deste trabalho é verificar a viabilidade da utilização do pó de placas cerâmicas queimadas, oriundas do descarte de placas em desconformidade e consideradas impróprias para venda, como substituição parcial do cimento Portland em argamassas.…”

O resíduo de placa cerâmica foi cominuído e caracterizado através de análise química e análise granulométrica. Em seguida, foram confeccionadas misturas com substituições de 5%, 12% e 20% do cimento Portland e determinados os índices de consistência, absorção da água, índice de vazios, massa específica, resistências à tração na flexão e resistência compressão axial para cada mistura. Os resultados mostraram que o resíduo de placa cerâmica é composto principalmente por SiO 2 (69,09%) e Al 2 O 3 (15,4%). A substituição de 5 e 12% ocasionou uma diminuição da porosidade dos corpos de prova. Os testes de resistência à tração na flexão mostraram um aumento nesta propriedade. Entretanto, os testes de resistência à compressão axial apresentaram um decréscimo de 0,9% e 2,5% para as substituições de 5 e 12%.

The ceramic plate waste was milled and characterized through chemical analysis and particle size analysis. Then, it was elaborated mixtures in order to replace 5, 12 and 20 wt.% of Portland cement by ceramic plates waste. In addition, the consistency indices, water absorption, void index, specific mass, tensile strength in flexion and axial compression were determined for each mixture. The results showed that the ceramic plates waste are composed by of SiO 2 (69.09 wt.%) and Al 2 O 3 (15.4 wt.%). The replacement of 5 and 12 wt.% decreased the mortar porosity. The tensile strength in flexion assays showed an increase on this property. However, the axial compression tests presented a decrease of 0.9% and 2.5% for replacement of 5 and 12 wt.%.

“…After cooling the specimen to room temperature, the sides of the specimens were sealed with silicone and then the specimens were placed on steel rods in a tray whereby water was filled up to the level of about 5 mm from the base of the concrete specimen. The quantity of water absorbed by the concrete specimens at intervals of 1,4,9,16,25,36,49 and 64 min were determined for calculation of the sorptivity index (Eq. 1).…”

“…In view of the benefits of re-using by-products as substitute for conventional concrete-making materials, there have been researches carried out to utilize recycled building materials such as construction and demolition waste [2,3], tiles [4] as well as ceramic wastes [5] in concrete. These research works have demonstrated that the wastes could be used satisfactorily as partial aggregate replacements in concrete.…”

“…This proportion is approximately four times larger than the waste produced by households and almost outnumbers the other types of waste dumped in landfills by over 50% [6]. The construction waste in landfills comprise 69% timber, 12% concrete, 10% metal, 7% brick, 0.43% plastic, and 2% other materials [5]. According to Bravo et al [6], given the differences in the composition of RCA and natural aggregate, the mechanical properties of the concrete that uses 100% RCA as a substitute aggregate are expected to decline in the future.…”

“…This phenomenon also reflects the rapid development and large consumption of such construction resources. Apart from plastic, glass, and scrap metal, construction waste is often dumped in landfills because of their non-recyclable properties [1][2][3], thereby leading to various landfill problems, such as area shortage and waste overload [4][5]. Malaysia shifts toward a green path by beginning to adopt a sustainable construction mode.…”

Abstract. Many construction and development activities today consume large amounts of concrete. The amount of construction waste is also increasing because of the demolition process. Much of this waste can be recycled to produce new products and increase the sustainability of construction projects. As recyclable construction wastes, concrete and ceramic can replace the natural aggregate in concrete because of their hard and strong physical properties. This research used 25%, 35%, and 45% recycled concrete aggregate (RCA) and ceramic waste as coarse aggregate in producing concrete. Several tests, such as concrete cube compression and splitting tensile tests, were also performed to determine and compare the mechanical properties of the recycled concrete with those of the normal concrete that contains 100% natural aggregate. The concrete containing 35% RCA and 35% ceramic waste showed the best properties compared with the normal concrete.
