“…On the other hand, the PO Fire-resistance, physical, and mechanical characterization of particleboard containing Oceanic Posidonia waste • 9 distribution in the PO-C boards is a random distribution of small particles leading to a compact structure, without areas of weakness. Additionally, the reduction of the particles' width results in better cohesion at the core of particleboard (24). As may be observed, PO-C-15 and PO-C-30 exceed the minimum requirements established for OSB panels.…”

ABSTRACT:In this work, particleboards manufactured with Oceanic Posidonia waste and bonded with cement are investigated. The particleboards are made with 3/1.5/0.5 parts of cement per part of Posidonia waste. The physical properties of bulk density, swelling, surface absorption, and dimensional changes due to relative humidity as well as the mechanical properties of modulus of elasticity, bending strength, surface soundness, perpendicular tensile strength and impact resistance are studied. In terms of the above properties, the best results were obtained for particleboards with high cement content and when the waste "leaves" are treated (crushed) before board fabrication, due to internal changes to the board structure under these conditions. Based on the results of fire tests, the particleboard is non-flammable without any fire-resistant treatment. RESUMEN: Caracterización física y mecánica de tableros fabricados con residuo de Posidonia Oceánica y su reacción frente al fuego.En esta investigación se han diseñado y fabricado tableros con residuo de Posidonia Oceánica y cemento. Los tableros se han fabricado con 3/1.5/0.5 partes de cemento por cada parte de Posidonia estudiándose sus propiedades físicas (densidad, hinchazón, absorción superficial, variaciones dimensionales por humedad) y mecánicas (módulo de elasticidad, resistencia a flexión, al arranque de superficie, al arranque de tornillo, a la tracción perpendicular y al choque). Se observa una mejora de los resultados de resistencia mecánica con el incremento de la cantidad de cemento y si la hoja del residuo es previamente tratada ya que proporciona una mejor estructura interna en el tablero. Además, tras los ensayos de reacción al fuego, se observa que el material es no inflamable sin ningún tipo de tratamiento ignifugante.

“…Se concluye que la mezcla de vermiculita más porosa ofrece mejor resultado de absorción y mejores resultados que la espuma, felpa, lana de vidrio, dosificaciones de cromita y el carbonato de calcio. En el sector doméstico es apta como materia base para la elaboración de tableros para muebles (González et al [113]), con buenas propiedades acústicas, térmicas y comportamiento a la humedad.…”

The work presented here focuses on the study of the acoustic behavior of rigid structure granular materials derived from natural products. Lightening materials are employed in construction. Severals products are extracted directly from quarry, being processed in industrial treatment plants to obtain the required properties. These materials do not contribute to environmental pollution from the point of view of the product nature. Products as arlite and vermiculite are available in the market with different particle sizes. These materials have very interesting properties: they exhibit high porosity, withstand high temperatures, have advantages from an economic point of view and their density is low.
