      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 ...
    • Efficient adsorbent based on construction and demolition wastes functionalized with 3-aminopropyltriethoxysilane (APTES) for the removal ciprofloxacin from hospital synthetic effluents 

      Chaguezac, Diana Fernanda Caicedo; Reis, Glaydson Simões dos; Lima, Éder Cláudio; Brum, Irineu Antônio Schadach de; Thue, Pascal Silas; Cazacliu, Bogdan; Lima, Diana Ramos; Santos, Arthur Hoffmann dos; Dotto, Guilherme Luiz (2020) [Journal article]
      An inorganic sludge from construction and demolition wastes (ICDW) was grafted with APTES to obtain an inorganic-organic modified adsorbent ICDW-APTES. This adsorbent was successfully employed for ciprofloxacin (CFX) ...
    • Fabrication, microstructure, and properties offired clay bricks usingconstruction and demolition waste sludge as the main additive 

      Reis, Glaydson Simões dos; Cazacliu, Bogdan; Cothenet, Alexis; Poullain, Philippe; Wilhelm, Michaela; Sampaio, Carlos Hoffmann; Lima, Éder Cláudio; Ambrós, Weslei Monteiro; Torrenti, Jean-Michel (2020) [Journal article]
      Green routes to prepare or manufacture sustainable building materials have been attracting muchattention over the years targeting sustainability issues. In this investigation, for thefirst time, sludgefrom the inert mineral ...
    • Some observations on the influence of particle size and size distributionon stratification in pneumatic jigs 

      Ambrós, Weslei Monteiro; Sampaio, Carlos Hoffmann; Cazacliu, Bogdan; Conceição, Paulo Ricardo Nunes da; Reis, Glaydson Simões dos (2019) [Journal article]
      Particle size variation plays a key role in jigging performance, and despite extensive research in the area, very little attention has been given in the case of pneumatic jigging. The aim of this study was to look into ...
