    • Characterization of demolished concretes with three different strengths for recycling as coarse aggregate 

      Sampaio, Carlos Hoffmann; Cazacliu, Bogdan; Ambrós, Weslei Monteiro; Kronbauer, Márcio André; Tubino, Rejane Maria Candiota; Dal Molin, Denise Carpena Coitinho; Oliva Moncunill, Josep; Miltzarek, Gerson Luis; Waskow, Régis Pereira; Santos, Viviane Lopes Gschwenter dos; Silva, Luis Felipe Oliveira (2021) [Journal article]
      This paper presents a physical characterization for the recycling into new concretes of three comminuted concretes: C16/20 (“ordinary concrete”), C50/60 (“high strength concrete”), and C70/85 (“very high strength concrete”). ...

    • Construction and demolition waste recycling through conventional jig, air jig, and sensor-based sorting a comparison 

      Sampaio, Carlos Hoffmann; Ambrós, Weslei Monteiro; Cazacliu, Bogdan; Oliva Moncunill, Josep; Veras, Moacir Medeiros; Miltzarek, Gerson Luis; Silva, Luis Felipe Oliveira; Kuerten, Ariane Salvador; Liendo, Maria Alejandra (2021) [Journal article]
      The paper presents a comparison of the concentration methods conventional jig, air jig, and sensor-based sorting to treat construction and demolition waste. All tests were made with concrete, brick, and gypsum particles ...

    • Current applications of recycled aggregates from construction and demolition : a review 

      Reis, Glaydson Simões dos; Quattrone, Marco; Ambrós, Weslei Monteiro; Cazacliu, Bogdan; Sampaio, Carlos Hoffmann (2021) [Journal article]
      A literature review comprising 163 publications published over a period of 26 years from 1992 to 2018 is presented in this paper. This review discusses the generation and recycling of construction and demolition waste (CDW) ...

    • Destoning the moatize coal seam, Mozambique, by dry jigging 

      Sampaio, Carlos Hoffmann; Ambrós, Weslei Monteiro; Cazacliu, Bogdan; Oliva Moncunill, Josep; José, David Selemane; Miltzarek, Gerson Luis; Brum, Irineu Antônio Schadach de; Petter, Carlos Otavio; Fernandes, Eunírio Zanetti; Oliveira, Luis Felipe Silva (2020) [Journal article]
      This paper proposes pre-beneficiation studies by air jigs of the coal layers from a Moatize coal deposit. Pre-beneficiation, also called destoning, removes tailings before the beneficiation plant. The air jigs operate in ...

    • Production of high-quality coarse recycled aggregates through a two-stage jigging process 

      Gschwenter, Viviane Lopes da Silva; Tubino, Rejane Maria Candiota; Ambrós, Weslei Monteiro; Miltzarek, Gerson Luis; Sampaio, Carlos Hoffmann; Oliva Moncunill, Josep; Cazacliu, Bogdan; Dal Molin, Denise Carpena Coitinho (2022) [Journal article]
      The use of recycled aggregates (RA) to replace natural aggregates (NA) in new concrete production has been pointed out as one of the main strategies to close the loop of construction materials. However, producing RA with ...
