“…In fact, the finer the material is, the higher its specific area and water demand. The workability of fresh mortar is controlled by several factors, such as fineness, water to binder ratio, shape of particles, and hydration rate [25,40]. Figure 7 shows an angular shape for SCM.…”

This study investigated the potential use of Zerdezas dam Calcined Sediments (CS) and El-Hadjar Blast Furnace Slag (GGBS) from northern Algeria as a partial replacement of cement (C) in normal hardening hydraulic road binders. Two binder mix designs were optimized using a Response Surface Methodology (RSM). The first mix, 50C35GGBS15CS, consisted of 50% cement, 35% blast furnace slag, and 15% calcined sediment. The second mix, 80C10GGBS10CS, consisted of 80% cement, 10% blast furnace slag, and 10% calcined sediments. The tests of workability, setting time, volume expansion, compressive and flexural strengths, porosity, and SEM were conducted to ensure that both mixes meet the standard requirements for road construction binders. The two proposed mixes were qualified as normal hardening hydraulic road binder. The reuse of the sediments will contribute to a better disposal of dam sediments and steel industry waste and to preserve natural resources that are used for manufacturing cement. It will also contribute to the environmental impact reduction of cement clinker production by reducing greenhouse gas emissions.

“…The growing demand for new SCMs has been mentioned in many sustainability reports as a route to decrease the CO 2 output of the construction industry in the short term (Scrivener et al, 2016;Monteiro et al, 2017;Habert et al, 2020;Pamenter and Myers 2021). Many primary and secondary resources are under investigation for use as SCM; a few examples are calcined clays (e.g., with 40 wt% kaolinite), biomass ashes, municipal solid waste incinerator ashes, steel slags, slags from the nonferrous metal industries, waste glass, mine tailings, spent pot lining, and BR (Aubert et al, 2006;Mladenovič et al, 2016;Scrivener et al, 2018;Bouchikhi et al, 2019;Juenger et al, 2019;Ohenoja et al, 2019;Danner and Justnes 2020;Hallet et al, 2020;Simonsen et al, 2020;Peys et al, 2021).…”

Co-Calcination of Bauxite Residue With Kaolinite in Pursuit of a Robust and High-Quality Supplementary Cementitious Material

2022

The present article investigates the potential of co-calcination with kaolinite as a sector-wide solution for the transformation of bauxite residue into an effective supplementary cementitious material (SCM). Bauxite residues from eight alumina refineries were co-calcined with 30 wt% of kaolinite at 750°C. SCMs with moderately high reactivities were obtained. Mortars with 30 wt% replacement of Portland cement (CEM I) by co-calcined bauxite residue had relative strengths of 73 ± 4%, 87 ± 4%, and 88 ± 2% after 2, 7, and 28 days compared to a CEM I reference mortar. The reactivity and contribution to strength development were shown to scale linearly with the kaolinite dosage. Most bauxite residues require only 20 wt% substitution by kaolinite to reach the reactivity and performance targets. Co-calcination reduced the mobility of heavy metals significantly. The negative effect on the workability that some BRs with higher content of free sodium exhibited was mitigated by co-calcination. This positive effect was also observed after calcination with 10 and 20 wt% of kaolinite. The same was found for the positive effect on the leaching of heavy metals. The inherent reactivity of the bauxite residue mainly stemmed from the desilication products such as sodalite and cancrinite. During co-calcination, the sodium-containing phases reacted with kaolinite, delivering a supplementary cementitious material with high reactivity and low free-sodium content.

“…The production of glass waste has a record of generation of powdered residues on a scale of at least 48 thousand tons of powder each year in Brazil (Rodier & Savastano Jr, 2018), and the adoption of powdered residues to improve the properties of the microstructure of cementitious matrix materials is one of the most developed aspects of study in the world due to the interesting characteristics it has: amorphous structure and a large amount of silicon present (Bouchikhi, Benzerzour, Abriak, Maherzi & Mamindy-Pajany, 2019).…”

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.
