Evaluation of the pozzolanic activity of fluid catalytic cracking catalyst residue (FC3R). Thermogravimetric analysis studies on FC3R-Portland cement pastes
TL;DR: In this paper, the influence of water/binder ratio and the replacement percentage of FC3R on the pozzolanic reaction were investigated by means of thermogravimetry (TG) of cured FC 3R-Portland cement pastes.
Journal ArticleDOI
Management and valorisation of wastes through use in producing alkali‐activated cement materials
TL;DR: In this paper, a review of the potential advantages and pitfalls associated with the application of alkali-activation technology to a wide variety of wastes that have been claimed to be suitable for the production of construction materials is presented.

Fluid catalytic cracking catalyst residue (FC3R): An excellent mineral by-product for improving early-strength development of cement mixtures
TL;DR: In this paper, a new industrial byproduct obtained from the fluid catalytic cracking (FCC) process in petrol refinery is studied for construction uses, which is composed of original spherically shape particles and fragments produced in the catalytic process (30-0.1 μm) that present highly irregular morphologies.
Journal ArticleDOI
Physical, chemical and mechanical properties of fluid catalytic cracking catalyst residue (FC3R) blended cements
TL;DR: In this paper, the use of fluid catalytic cracking catalyst residue (FC3R) as a cement replacement material has been studied and four FC3R-blended cements were prepared by the replacement of Portland cement by FC3r in the 6-20% range by mass.

Characteristics of lime-silica fume mixtures
TL;DR: In this article, the hydration of two calcium hydroxide-silica fume mixtures at 25°C was studied and the molar ratios CaO/SiO2 and H2O/SO2 molar in the calcium silicate hydrates (C-S-H) formed were identified by using differential thermal analysis.
