Using spent fluid catalytic cracking (FCC) catalyst as pozzolanic addition - a review

Abstract

Spent fluid catalytic cracking (FCC) catalyst is an oil industry by-product from fluidised-bed catalytic cracking units. This residue is mainly formed by an active component (faujasite type zeolite Y) in an amorphous aluminosilicate matrix. It mainly consists of up to 90% silica and alumina. This paper reports an extensive literature review regarding the characterisation and mechanical and durability properties of mortar and concrete added to this material. FCC has been studied lately due to its pozzolanic characteristics and the good performance of concrete mixtures using FCC as cement replacement.

Eco-Efficient Concrete Using Industrial Wastes: A Review

“…Some authors [37] showed that FBCC (a waste from the petrochemical industry) is a zeolite material containing more than 50% SiO 2 and about 40% Al 2 O 3 . This material improves concrete strength and increases its durability [38].…”

Cementinio rišiklio su pramonės atliekomis ir nanosilicio dioksidu, skirto vandeniui laidžiam betonui, modifikavimas ir tyrimai

“…Toks efektas paaiškinamas dideliu NK paviršiaus plotu ir akyta mikromorfologija, turinčia didelę trauką vandeniui, kuri lemia didelę vandens absorbciją (20-30 %). Didelė NK dalelių vandens absorbcija, kuri paprastai skatina cemento pagrindu pagamintų medžiagų sklidumo sumažėjimą, gali būti technologinis trūkumas (Payá et al, 2013;Allahverdi et al, 2011;Su et al, 2001;Castellanos & Agredo, 2010;Tseng et al, 2005).…”
