Abstract

This research aimed to evaluate the potencial use of residues of Pinus spp. sawnwood production and partial substitutions of Portland cement for fly ash and blast slag furnace, in cement-wood composites. The physical characteristics (density, porosity and water absorption) and mechanical characteristics (compression and traction resistances) of the composites were evaluated in agreement with the ABNT normalization. The amount of substituition to the Portland cement for 5% to 40% of fly ash and 25% to 60% of blast slag furnace were evaluated. In both cases chemical addictive, to accelerate de cement hydration (CaCl2 .2H2O), were used. The results demonstrated the technical feasibility to residue of Pinus spp. use, and substitutions of Portland cement in composite, accordingly to optimized values obtained by multivariate statictical analysis, were 5% of fly ash and 25% of blast slat furnace.
