This work is intended to promote the suitability of newsprint paper waste as one component of light-weight composite panels, using gypsum as a binder. The manufacture of agro-gypsum panels from corn stalks, a light lignocellulosic material, was taken as a basis for comparison. Promoting the newsprint paper involved carrying out two series of trials. First the authors studied the surface treatment of the cellulosic fibers before and during panel formation, using sodium silicate in combination with magnesium chloride, and then we added an acrylic polymer and/or replaced the gypsum by industrial waste, for example, phospho-gypsum or cement dust. Big improvements in the physicomechanical properties (low density, high water resistance, and compressive strength) of agro-gypsum panels can be obtained by replacing the gypsum with cement waste in the presence of the acrylic polymer. According to the compressive strength required, construction panels were manufactured from surface-treated waste paper with gypsum, and/or phospho-gypsum and cement dust, in absence or presence of acrylic polymer. Panels for thermal insulation were obtained from treated corn stalks and gypsum instead of waste paper. Addition of acrylic polymer or replacing the gypsum by phospho-gypsum or cement dust, improved the suitability of the corn stalks panels for construction applications. |
