Resumen
El objetivo de este trabajo es analizar la factibilidad de uso de carozos de durazno, desecho biomásico del sectorfrutihortícola, como formador de poros en la fabricación de piezas cerámicas alivianadas. Se prepararon mezclas dearcilla comercial con el agregado de 5%, 10%, 15% y 20% en volumen de carozos y una muestra de arcilla sinagregados a modo de referencia. Todas las mezclas con un agregado de 8% de humedad se conformaron en moldes de70 mm x 40 mm, utilizando una presión de compactación de 25 MPa. El tratamiento térmico fue 1000°C durante 3horas, a una velocidad de calentamiento de 1°C/min. Los resultados obtenidos reflejan una alta factibilidad deutilización de esta biomasa para el uso estudiado. Los productos cerámicos obtenidos poseen buenas propiedadesgenerales, aunque las propiedades mecánicas son un limitante ya que cumplen con los requerimientos del mercadohasta agregados del 10% de material residual.
The objective of this work is to analyze the feasibility of using peach pits, biomass waste from the fruit and vegetable sector, as a pore former in the manufacture of lightweight ceramic pieces. Commercial clay mixtures were prepared with the aggregate of 5%, 10%, 15% and 20% by volume of pits and a clay sample without aggregates for reference. All mixtures with an aggregate of 8% humidity were formed in molds of 70 mm x 40 mm, using a compaction pressure of 25 MPa. The heat treatment was 1000°C for 3 hours, at a heating rate of 1°C / min. The obtained results reflect a high feasibility of using this biomass for the studied use. The ceramic products have good general properties, although the mechanical properties are a limitation since they meet the market requirements up to 10% aggregates of residual material.
