Study of mortars added with fluid catalytic cracking catalyst residue (FCC) under the influence of high temperatures
Main Article Content
In this article, the effect of the addition of a petrochemical industry residue, called spent catalyst from the catalytic cracking (FCC), in cementitious materials exposed to temperatures of 25 °C, 200 °C, 300 °C, 500 °C, 750 °C, 1000 °C and 1200 °C was analyzed. Metakaolin (MK) and silica fume (HS) were used as reference materials. The additions were incorporated into a 10% replacement of the proportion of cement (OPC) in the mixture. The effects of temperature exposure in the weight change and compressive strength were evaluated. Also, changes in the physical appearance of the specimens after thermal exposure were studied. Techniques of Thermogravimetric Analysis (TG) and scanning electron microscopy (SEM) were used to analyze the changes. The results indicate that the addition of the FCC acts positively on the performance of Portland cement. It is noteworthy that the residual strength of OPC mortars at temperature of 750 °C is 16.53% of the strength at room temperature compared to the mortars added, which reach up to 29.24%. The FCC addition delayed the appearance of cracks in the elements exposed to high temperatures compared to those without addition; its residual strength at 750°C is 26% higher than the reference material (OPC).
