TORRES AGREDO, JANNETH; BAQUERO, EDWIN ARLEY  e  SILVA, ALEX RICARDO. EVALUATION OF THE POZZOLANIC ACTIVITY OF FLUID CATALYTIC CRACKING RESIDUE. Dyna rev.fac.nac.minas [online]. 2009, vol.76, n.158, pp.49-53. ISSN 0012-7353.

In the present article results of the evaluation of the pozzolanic activity of fluid catalytic cracking residue (FCC) proceeding from the petrol industry, are presented. Possibility of FCC as an addition to cement for the production concrete and mortars was studied. The pozzolanic activity of the FCC was evaluated according to ASTM C311 and C618, thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC) techniques. The results showed that this waste can be used as addition to the cement in mortars and concrete, adding to its importance of the utilization.

Palavras-chave : Fluid catalytic cracking residue; pozzolanic activity; mortars; differential scanning calorimetry; thermogravimetric analysis.
