Effect of FC3R on the properties of ultra-high-performance concrete with recycled glass

Abstract

Ultra-high-performance concrete (UHPC) is the essential innovation in concrete research of the recent decades. However, because of the high contents of cement and silica fume used, the cost and environmental impact of UHPC is considerably higher than conventional concrete. The use of industrial byproducts as supplementary cementitious materials, in the case of recycled glass powder and fluid catalytic cracking catalyst residue (FCC), the partial substitution of cement and silica fume allows to create a more ecological and cost-efficient UHPC. This research presents a study to determine the possibility of partial substitution of cement by FCC in a previously optimized mixture of ultra-high-performance concrete with recycled glass. The results demonstrate that compressive strength values of 150 and 151 MPa without any heat treatment can be achieved, respectively, when replacing 11% and 15% of the cement with FCC, for a determined amount of water and superplasticizer, compared to 158 MPa obtained for the reference UHPC without any FCC content. The rheology of fresh UHPC is highly decreased by replacing cement particles with FCC.

A Comprehensive Overview of Recycled Glass as Mineral Admixture for Circular UHPC Solutions

“…Tagnit-Hamou et al [52] studied the implication of the curing temperature and the amount of water in CS of waste glass-UHPC at 2, 28 and 91 days. The tests pointed out that the inclusion of GP as a cement partial replacement increases the spread flow, a factor that allows it to work with a lower w/b [27,75]. Also, with more than 20% of cement replacement with GP, the CS at 28 days was slightly lower than the control [52], but this pattern changes with 91 days of normal curing and with hot curing.…”

“…The study highlighted the importance of incorporating supplementary cementitious materials for enhancing both the mechanical strength and sustainability of UHPC. The effect of high reactive aluminosilicates cementitious materials, like metakaolin (MK) and Fluid Catalytic Cracking Catalyst Residue (FC3R), in waste glass-UHPC was explored [3,27]. Due to the reaction of the high alumina-silicate components of FC3R and MK, yielding ettringite formation, those cementitious materials showed potential for enhancing early-age strength, but their impact on long-term strength and workability was observed to vary based on substitution levels.…”

“…Hence, the findings of these investigations illustrate the collaborative effect of limestone and glass powder in alleviating rheological issues in mixtures containing FR3C or MK. Thereby, with the optimal dosage of these high alumina materials, the effect of glass and limestone allows the UHPC to exhibit beneficial properties for early strength development, all the while maintaining cost-effectiveness, a proper rheology feature in the fresh state, and reducing the carbon footprint [3,27].…”

“…This way, one must meticulously choose micro-and nano-sized components that can effectively fill the gaps between larger particles, resulting in an improved packing arrangement [22]. It is worth mentioning that certain materials, like SF, quartz powder, slags, fly ash and others, are frequently utilized in this application owing to their fine particle size and pozzolanic features [2,3,6,[23][24][25][26][27][28][29]. Understanding the achievement of optimal density in concrete relies on the use of particle-packing models, like the modified Andreasen and Andersen (A&Amod) or the Compressive Packing Model (CPM) [19].…”
