Comportamiento de tejas de diferente color (rojo y paja) frente al biodeterioro

Abstract: (2)Instituto de Recursos Naturales y Agrobiología (IRNAS). CSIC. Sevilla. Spain INTRODUCCIÓNDurante años, el deterioro de los materiales, se ha atribuido únicamente a la acción de procesos físicos y químicos, pero realmente, se ha demostrado que la acción de microorganismos, tales como bacterias, cianobacterias, algas, hongos o líquenes, es uno de los principales factores que afectan al deterioro de los materiales [1][2][3][4][5].Históricamente, las tejas cerámicas son materiales que presentan una durabilidad … Show more

“…It acts as a degreaser in the paste, favoring the degassing of impurities and the elimination of water during the drying process and reducing linear shrinkage and deformation during firing [27]. The content of alumina of the analyzed raw materials is approximately 21 %, enough quantity to provide the clay with high melting temperature, low thermal conductivity, high resistance to corrosion, low expansion coefficient, and hardness [28]. The results obtained from the feldspar show that it is an alkaline potassium-sodium type, with a low sodium proportion and traces of barium compared to potassium.…”
