Caracterización mecánica del material compuesto de matriz de yeso reforzado con residuos de madera de pino

Abstract

Abstract: The present work intends to generate knowledge that, added to the requirements of the current regulations, help to change the life cycle that is currently given to pine wood residues in search of a possible application in the field of construction. It is proposed to use a gypsum matrix with the intention of obtaining a light material with thermal and acoustic insulation properties. In addition, properties such as low density, rapid hardening and good workability make this matrix potentially significant for the search for an alternative construction material free of gray cement that contributes to the reduction of CO2 release in favor of sustainability. The characterization of the gypsum matrix composite material reinforced with pine wood residues was carried out in plates, since it is the most common way that this matrix is used in the construction systems applied in our environment. To carry out this characterization, the following tests were carried out: specific weight, moisture content, flexural strength by modulus of elasticity, water absorption by immersion, capillarity coefficient, heat transfer, gross acoustic insulation and airborne noise, fire resistance and gas emission. With the results of the tests carried out, it was sought to establish the adequate percentage of pine wood reinforcement for its incorporation into a plaster matrix, as well as to compare these results with the minimum requirements established in the current standard.
