“…Consequently, small differences in mineral content were possible. The absence of alite in the diffractograms may have resulted from an instability in the cooling process, reverting to the more stable dicalcium silicate [ 39 ] or by the presence of potassium present in the sludge from the processing of ornamental rocks that hindered the reaction of belite with CaO [ 13 ].…”

“…Enríquez et al [ 13 ] evaluated belitic clinker production from carbonate calcium sludge, cement furnace ash, and rice husk ash without the use of limestone and clay. Belitic-based clinker was obtained at 1350 °C with high hydration kinetics and large heat release at initial ages.…”

Environmental concerns have come to the forefront due to the substantial role of the cement industry in the extraction and expenditure of natural resources. Additionally, industrial processes generate a considerable amount of waste, which is frequently disposed of inadequately. The objective of this study was to evaluate the simultaneous use of ornamental rock processing sludge and calcium carbonate sludge generated from the kraft process in the production of belitic clinker. These waste materials would be used in total or partial substitution of natural raw materials, namely, limestone and clay. Several formulations were produced and sintered at 1100 and 1200 °C. The raw materials were characterized physico-chemically and thermogravimetrically, with subsequent evaluation of the resulting dosed raw mixes. Mineral analyses determined that the mixtures with limestone and clay in substitution ratios of 95% and 100%, respectively, and sintered at 1100 °C have the potential to produce belite-rich clinkers. This temperature is considerably lower than those reported in reference studies. Additionally, full limestone and clay substitution could result in a 23.92% reduction in carbon dioxide in clinker production. The results confirmed the potential use of ornamental rock processing sludge and calcium carbonate sludge as viable alternative materials for cement production and, consequently, could contribute to a reduction in the negative environmental impacts of this industry.

“…It is generally accepted that the main constituents of OPC include Alite, Belite, Celite and Felite (Enríquez et al, 2020;Plank, 2020;Nari and Praneeth, 2021). To obtain cement-like material with a chemical composition similar to OPC, the synthesized Alite, Belite, Celite and Felite were mixed together.…”

Importance of the work: Utilization of bio-waste-based construction materials is an effective route to create a more sustainable ecosystem. Objectives: This research investigated fabricating lightweight cement blocks prepared from bio-wastes. Additionally, the bio-waste-based cement blocks were tailored to include antibacterial properties. Materials & Methods:The synthetic cement-like material was prepared using a solution combustion technique, with cockleshells and rice husk ash as the key raw materials. Rice husk ash (20-60 wt%) was added to the cement-like material prior to casting. The density, compressive strength and antibacterial performance of the cement blocks were evaluated. Results: It was found that increased rice husk ash suppressed the compressive strength. Nevertheless, the average density (1.004 g/cm3) and average compressive strength (3.65 MPa) of all cement blocks were in the acceptable ranges for industrial requirements based on recognized standards, specifically Thai Industrial Standards Institute Type C12 (TISI 2601-2556). Enhancement of the compressive strength by more than 10% could be achieved when jute fibers were added. A colony count method was used to determine antimicrobial performance of the lightweight cement blocks. Addition of the powder obtained from the cement blocks into the Petri plates containing Gram-positive Staphylococcus aureus and Gram-positive Bacillus cereus indicated successful reductions of more than 99% of Staphylococcus aureus and Bacillus cereus colonies. Main finding: Cement-like material, which was successfully synthesized from bio-waste, was used in fabrication of jute fiber-reinforced eco-friendly lightweight cement blocks. In addition to acceptable density and compressive strength, the cement blocks demonstrated antibacterial performance.

“…On the other hand, building materials have heterogeneous compositions and microstructures; therefore, they tolerate compositional variations in waste from different campaigns. In recent decades, several studies have focused on the reuse of waste as a raw material in the manufacture of different construction materials, such as various types of clinker [ 5 ], cement [ 6 , 7 , 8 ], mortars [ 9 ], concretes [ 10 , 11 , 12 , 13 ], geopolymers [ 14 , 15 ], clay bricks [ 16 , 17 , 18 , 19 , 20 ], ceramic tiles [ 21 , 22 ], and roof tiles [ 23 , 24 ].…”

In this study, different lightweight expanded glass aggregates (LEGAs) were produced from glass cullet and various carbonated wastes, through a thermal impact process. The effects of LEGA microstructure and morphology on both the adherence to the cement paste and the mechanical properties of mortars after 28 days of curing were studied. The properties of lightweight mortars made of either LEGAs or expanded clay aggregates were compared. The results demonstrated the feasibility of using LEGAs to produce glass lightweight aggregate mortar, with flexural and compressive strength values ranging from 5.5 to 8.2 MPa and from 28.1 to 47.6 MPa, respectively. The differences in mechanical properties were explained according to the microstructures of the fracture surfaces. Thus, arlite-type ceramic aggregates presented surface porosities that allowed mortar intrusion and the formation of an interconnected interface; although the surfaces of the vitreous aggregates were free from porosity due to their vitreous nature, the mortars obtained from different wastes presented compressive and flexural strengths in the range of lightweight mortars.
