    Lightweight concrete : an alternative for recycling cellulose pulp
    (2015-04) Andrés, Federico N.; Beltramini, Loreley B.; Guilarducci, Anabela Guadalupe; Romano, Melisa S.; Ulibarrie, Nestor Oscar
    From the analysis of the production process of molded pulp packaging, it can be seen that one of the residues generated in the molding is "pulp". When this waste cannot be reincorporated into the production line, is recovered by centrifugation in the effluent treatment system. With the intention of recycling this residue it was investigated the feasibility of their use in the manufacture of concrete blocks or panels lightened studying possible ways to use the material, either in the wet state (form is discharged from the process) or dry (dried in a controlled environment), analyzing the advantages and disadvantages of each alternative. For practical purposes, various dosages were proposed to maintain constant the amount of residue and varying the amounts and proportions of water and cement. Test specimens were made with various amounts of cement per m³ of concrete.

    Waste of molded pulp industry. Filler panel production for construction
    (2015-04) Andrés, Federico; Beltramini, Loreley B.; Guilarducci, Anabela Guadalupe; Romano, Melisa; Ulibarrie, Nestor Oscar
    In the production process for producing recycled pulp cellulose, there are waste generated by the raw material entering the system. This residue is separated from the pulp by physical methods, and is mainly composed of plastics, paper, laminated papers and other materials in smaller proportions. In order to recycle this waste, in this paper we analyze the viability of use in the production of insulated panels. With the untreated residue extracted from the plant, panels of 30 cm side and thickness of approximately 6 cm were made. On these panels, parameters such as density and compression strength were evaluated for the study of the homogeneity of the material obtained
