“…As expected, high percentages were observed for SiO2 (67.01%), CaO (13.76%), and Na2O (9.58%), confirming that the glass residue used is soda-lime-silicate, in addition to being close to the percentages stipulated by Vogel (1994), Shelby (2005, and Bauer (2019) as a soda-lime-silicate glass system. Comparing the quantities of these main oxides with those presented in the studies on UHPC that used the residue as an alternative raw material, a great similarity was observed with the studies by Vaitkevičius, Šerelis and Hilbig (2014), Soliman and Tagnit-Hamou (2016), Soliman and Tagnit-Hamou (2017a), Tagnit-Hamou (2017b), Mosaberpanah, Eren andTarassoly (2019), Pezeshkian, Delnavaz and Delnavaz (2019), Wilson, Soliman, Sorelli and Tagnit-Hamou (2019) and Jiao et al (2020), being an indication of the compatibility with the UHPC systems of the studied glass residue.…”

The exponential advancement of cutting-edge technologies in the scope of civil construction, seeks to give cement-based materials the eco-efficient potential linked to mechanical performance that enables different applications. This work aims to evaluate the glass residue regarding the pozzolanic potential through ABNT NBR 5752:2014, as well as to verify whether through the characterization tests of x-ray fluorescence, x-ray diffraction and laser diffraction granulometry, if it is viable of application as supplementary cementitious material (filler), in ultra-high performance concrete. The glass residue submitted to the tests proposed in this study, was crushed in a jaw crusher, milled in a bench ball mill at 47 rpm, and was sieved in a 75 µm opening mesh (ABNT nº 200 mesh). For the test of pozzolanic activity, CP II F-40 class cement, normal sand, water from the public supply network, and superplasticizer additive were used for the mix with 25% of the residue replacing cement, while for the other characterization techniques, the glass residue was applied in its processed form (after sieving), dry or wet. The evaluated glass residue did not reach the minimum rate of 75% established by ABNT NBR 5752:2014, achieving only 45.72%, being classified as non-pozzolanic, which indicates its inert behavior in the presence of calcium hydroxide. The characterization tests confirmed, based on the specialized literature on ultra-high performance concrete, its viability as a filler when adopted as an alternative raw material for presenting chemical and mineralogical composition, in addition to granulometric distribution, very close to those used in studies that demonstrated satisfactory results when using the glass residue as an input.

“…In UHPC mixtures, studies have shown that partially replacing cement (up to 30%) and silica fume (up to 50%) with a natural pozzolan resulted in UHPC specimens with very low (or negligible) chloride ion penetration and drying shrinkage of less than 500 μstrain, whereas workability and mechanical properties of these UHPC mixtures did not substantially change [ 21 , 22 ]. However, the literature reporting the effects of natural pozzolans in non-proprietary UHPC is severely lacking and each of these studies either used aggregates with a maximum size less than 1.2 mm, optimized gradation, or both [ 21 , 22 , 23 ]. Using ultra-fine aggregates or an optimal gradation increases UHPC production cost which negatively impacts sustainability.…”

A Comprehensive Study on Non-Proprietary Ultra-High-Performance Concrete Containing Supplementary Cementitious Materials

et al. 2023

Ultra-high performance concrete (UHPC) is a novel cement-based material with exceptional mechanical and durability properties. Silica fume, the primary supplementary cementitious material (SCM) in UHPC, is expensive in North America, so it is often substituted with inexpensive class F fly ash. However, future availability of fly ash is uncertain as the energy industry moves toward renewable energy, which creates an urgent need to find cost-effective and environmentally friendly alternatives to fly ash. This study investigated replacing cement, fly ash, and silica fume in UHPC mixtures with ground granulated blast-furnace slag (GGBFS), metakaolin, and a natural pozzolan (pumicite). To identify acceptable UHPC mixtures (28-day compressive strength greater than 120 MPa), workability, compression, and flexural tests were conducted on all mixtures. Then, durability properties including shrinkage, frost resistance, and chloride ion permeability (rapid chloride permeability and surface resistivity tests) were evaluated for the acceptable UHPC mixtures. Results showed that 75, 100, and 40% of fly ash in the control mixture could be replaced with pumicite, metakaolin, and GGBFS, respectively, while still producing acceptable strengths. Flexural strengths were greater than 14.20 MPa for all mixtures. For durability, UHPC mixtures had shrinkage strains no greater than 406 μstrain, durability factors of at least 105, and “very low” susceptibility to chloride ion penetration, indicating that these SCMs are suitable candidates to completely replace fly ash and partially replace silica fume in non-proprietary UHPC.

“…UHPC is a promising material for reinforced concrete structures because it has significant potential for creating new architectural perspectives as well as structural systems with a prolonged service life and low maintenance costs thanks to its superior durability performance [13]. Due to its hydraulic action, high strength activity, and fineness value [14], GGBS may be one of the best alternative cementitious materials for use in UHPC that will allow for a reduction in Portland cement dosage while maintaining satisfactory performance.…”

Ultra-high performance concrete (UHPC) is an innovative cement-based composite with high mechanical performance under tensile and compressive loads, extremely low permeability, and excellent durability. Because of these features, UHPC has the potential to contribute to the development of new architectural perspectives and structural systems with prolonged service life; therefore, it is anticipated that the use of UHPC in cast-in-situ applications will increase in the near future. As a result of its high Portland cement dosage, the hydration heat of UHPC can be relatively high compared to that of conventional concrete. Thus, ground granulated blast furnace slag (GGBS) can be used in UHPC formulation for reducing Portland cement dosage thereby limiting hydration heat while also addressing ecological and engineering concerns. In the scope of this study, the effects of GGBS replacement (0%, 30%, and 60%) on the hydration heat, strength, and microstructural characteristics of UHPC were studied. Results showed that GGBS-bearing UHPCs are more sensitive to ambient temperature in respect to cumulative heat. 60% GGBS replacement reduced cumulative heat release by 36% and 28% at 20 • C and 35 • C respectively. So, the benefit of GGBS on reducing hydration heat is less pronounced in hot weather. Performance differences in strength depending on the replacement ratio were only noticeable on the first day of curing. Prolonged curing time and fiber inclusion eliminated strength differences. Microstructural investigations indicated that Ca(OH) 2 can be lowered up to 0.5%, and the Ca/Si ratio of the C-S-H phase was reduced below the value of 1.0 after 90 days of curing as a result of GGBS replacement.
