Evaluación de la toxicidad de un residuo industrial estabilizado/ solidificado con cemento Portland Toxicity evaluation of an industrial waste stabilized/ solidified with Portland cement

This study evaluates the toxicity associated with Portland cement mortar blended with a residue of the petrochemical industry called catalytic cracking catalyst waste (FCC) using the technique of Solidification/Stabilization (S/E). The techniques of X-Ray Fluorescence, X-Ray diffraction and Infrared Spectroscopy permitted to evaluate the Chemical and mineralogical characteristics of the residue. Leaching of heavy metals on blended mortars with 20% w/w of FCC - determined by the tests Toxicity Characteristic Leaching Procedure (TCLP), Synthetic Precipitation Leaching
