Abstract

This paper analyzes the feasibility of using a residue of spent catalyst (FCC) of the cracking process, from a Colombian oil company, in the production of building elements such as locks and pavers. To define the optimal mix of portland cement/FCC, Portland cement mortars with FCC ratios between 0 and 70% as replacement of cement were prepared and its compressive strength is evaluated at ages up to 28 days of curing. Using a statistical processing, applying the methodology of response, the proportions of each component in the mixture are optimized. In addition the study of the prcess of hydration is performed by techniques of X-ray diffraction (XRD) and differential thermal analysis (TG / DTG). The results indiocate that it is possible to incorporate into the concrete FCC as replacement of cement up to 45% and obtain a building element with mechanical properties comparable to those commercially available elements. According to the Colombian standard, the elements developed in this research classified as non-structural blocks and floor pavers. It raises this is an alternative use of the residue and contribute to environmental sustainability.
