Avaliação da resistência à compressão do compósito cimento-madeira em diferentes concentrações de serragem de Araucaria angustifolia (Bertol.) Kuntze

Abstract

The growing concern about the environment leads to the search for ways to reduce the waste emission or a way to reuse full stop the sawmill sector of Pinus spp. the efficiency of logs reaches approximately 54%, with a large production of residues that can be used for the manufacture of the cement-wood composite. This composite has been used since 1920 in Austria, having its diffusion around 1976, when large production started in Germany and spreaded to some countries in Asia, Mexico and the United States. Its acceptance relies its diverse applications such as a woden panel due to its thermal and acoustic insulation characteristics. Aiming to expand its applicability and consequently to make a material more popular, this work demonstrated that the application of this material in the form of a structure is unlikely in the composition used in this work. However, other possible uses for the application of this mixture were identified.
