TROCHEZ, Jenny Johanna; TORRES AGREDO, Janneth  and  MEJIA DE GUTIERREZ, Ruby. Study of hydration of cement pastes added with used catalytic cracking catalyst (FCC) from a colombian refinery. Antioquia [online]. 2010, n.55, pp.26-34. ISSN 0120-6230.

This paper analyzes the effect of the incorporation of industrial waste from an oil refinery in Colombia, known as used catalytic cracking catalyst (FCC), in the hydration process of cementitious pastes. For this purpose, ordinary Portland cement pastes (OPC) added in percentages of 10 and 20% of FCC were prepared. The pozzolanic reactivity of the material and type of hydration products were determined by X-ray diffraction (XRD) and thermogravimetric analysis (TG / DTG). Additionally, the heat of hydration released was determined based on the standard ASTM C186. The results indicate that the hydration process of FCC blended cement is strongly exothermic as a consequence of its pozzolanic activity. The main phases present in the blended cement system were the calcium silicate hydrates (CSH gel), calcium aluminate hydrates (CAH) y calcium aluminosilicate hydrates (CASH), similar to the products obtained in metakaolin blended cement pastes.

Keywords : Catalytic cracking catalyst; blended cement pastes; pozzolanic reactivity; hydration products; heat of hydration.
