Abstract

Graphical abstract: Highlights: Density and Resin factors act independently for the mechanical and thermal properties. For physical and thermal properties, the Density and Resin factors behave in a dependent manner. It is possible to reduce the resin content by 3% for MOR, as long as the density is 0.54 g cm −3 . For WA, it is possible to reduce the amount of resin to 12% for the panels (0.40 e 0.50 g cm −3 ). For thermal conductivity, it is possible to reduce the amount of resin to 12%. Abstract: This study investigated the potential use of cement bags disposed in civil works as a raw material for the manufacture of particulate boards. The cement bags were recycled particles and these particles used to manufacture panels for three different densities (0.4, 0.5 and 0.6 g cm −3 ) and two levels (12 and 15%) of resin (polyurethane castor oil). The results showed that the density and the resin differently influence the performance of mechanical, physical and thermal panels, which suggests the possibility to reduce by 3% the amount of resin in the formulation of the panels.
