| dc.description.abstract | This paper describes research on viability of producing self-compacting concretes (SCCs) with ternary blends of powder materials comprising cement, limestone powder (L) and a waste catalyst generated at the fluid cracking catalytic unit (FCC) by the oil-refinery industry. For this purpose, an experimental program was conducted to iteratively design mixture proportions of SCCs using 30% (v/v) limestone powder and 0-30% (v/v) of waste FCC catalyst as partial cement replacements in the powder materials blends. Tests of fresh-state SCCs were conducted for slump flow, V-funnel, and L-box. Compressive strength tests of hardened SCCs were conducted at 3, 7, 14 and 28 days of curing time. Results showed that SCCs containing high volumes - up to 60% (v/v) - of both additions, limestone and waste FCC catalyst, in powder materials blends achieve adequate self-compactability in compliance with European standard EN 206-9. Moreover, waste FCC catalyst incorporation in concretes composition leads to compressive strength gains. Besides standard requirements being fulfilled and the improvement in the concrete performance, the ample availability of the waste FCC catalyst (around 500 kton) in oil refineries worldwide make this waste a potential steady supply for the concrete industry. As such, large-scale manufacturing of innovative SCCs with recycle waste FCC catalyst is feasible in the future, making a significant contribution to lower the carbon footprint of the construction materials. | pt_PT |
