| description | This research was developed with the objective of evaluating the potential use of residues of the production of sown Pinus spp wood and partial substitutions of Portland cement for high performance metakaolin and residue of calcined ceramic in cement-wood composites. The evaluation of the physical characteristics (specific mass, porosity and water absorption) and mechanics characteristics (compression and traction resistances) of the composites were determined in agreement with the ABNT standards. The was levels of substitution to the Portland cement for 5% to 40% of high performance metakaolin and 5% to 40% of residue of calcined ceramic. In both cases additive chemicals (CaCl2.2H2O) to speed up the cure of the cement were used and super-plasticizer to maintain without altering the rheological characteristics of the composite. The results demonstrated the technical viability to the use of the residue of Pinus spp and the for substitutions of the cement Portland in composites, and the optimized levels, obtained through multivariate statistical analysis, were 10% of high performance metakaolin and 5% of residue of calcined ceramic. |

Este trabalho teve como objetivo avaliar o potencial de utilização do resíduo do desdobro de toras de Pinus spp. e de substituições parciais do cimento Portland por metacaulim de alta reatividade e resíduo de cerâmica calcinada, em compósitos cimento-madeira. As características físicas (massa específica, índice de vazios e absorção de água) e mecânicas (resistência à compressão e a tração) dos compósitos, foram determinadas conforme normas da ABNT. Foram testadas substituições do cimento Portland por teores de 5% a 40% de metacaulim de alta reatividade e 5% a 40% de resíduo de cerâmica calcinada. Em ambos casos foram utilizados, aditivos químicos (CaCl2.2H2O) para acelerar a pega do cimento e superplastificante, a fim de manter inalteradas as características reológicas do compósito. Os resultados demonstraram a viabilidade técnica da utilização do resíduo de Pinus spp. e das substituições parciais do cimento Portland dos compósitos. Os valores otimizados destas substituições foram determinados através de análise multivariada, sendo de 10% para o metacaulim de alta reatividade e de 5% para o resíduo de cerâmica calcinada.
