The increasing popularity of geopolymer concrete is attributed to its small ecological footprint. Moreover, it presents substantial prospects for employing industrial waste as a substitute binder for producing geopolymer concrete. The ceramic waste powder (CWP), which is a by-product of the ceramic polishing and glazing process, was employed in the manufacturing of geopolymer mortar. This study investigated the heat and abrasion resistance of geopolymer mortar (GM) produced using two different types of CWP and fly ash. A GM was prepared by combining fly ash, CWP, and the alkaline activators NaOH and Na2SiO3. The study examined three different curing conditions: ambient, curing at 60 °C for 24 hours, and curing at 60 °C for 48 hours. All mortar mixes were heated to temperatures of 500°C and 1000°C for a period of 2 hours (h) to study their heat resistance. Both weight loss and compressive strength (CS) were assessed before and after temperature exposure. The assessment of abrasion resistance was conducted in line with the Indian standard. The study suggests that the utilization of CWP enhances the high temperature and abrasion resistance of GM.

“…Also, in cement-based materials, remarkable improvements in mechanical properties and durability can be achieved if the potential activity of slag can be activated by some alkaline substances, i.e., alkali-activated slag (AAS). Compared with ordinary Portland cement, AAS possesses a higher strength, shorter setting time, better resistance to chemical erosion and lower hydration heat owing to its potential hydraulic activity [ 27 , 28 , 29 , 30 , 31 , 32 ]. Therefore, it can be inferred that AAS has great potential to be used as a stabilization agent for soil, which may provide a reasonable method for the utilization of the industrial waste slag and development of resource-saving and environment-friendly manufacturing industries.…”

Discharged slag not only occupies a large amount of land for disposal, but also causes serious environmental pollution. The use of alkali-activated slag (AAS) instead of cement as a soil-stabilization agent is beneficial for industrial waste disposal and energy conservation, which complies with the concept of green and low-carbon sustainable development in the construction industry. In this study, the compressive strength, water permeability coefficient, chloride migration coefficient and sulfate resistance of alkali-activated slag-stabilized soil (AASS) were evaluated, and compared with those of cement-stabilized soil (CSS). The hydrated crystalline phases and microscopic pore structures were analyzed by X-ray diffraction, electrochemical impedance spectroscopy (EIS) and mercury intrusion porosimetry (MIP) tests, respectively. The results indicate that, compared with CSS, AASS exhibits a higher compressive strength, lower water permeability, chloride migration coefficient and better resistance to sulfate attack, with the optimum dosage higher than 10 wt.%. The results of the MIP analysis show that the addition of AAS reduces the porosity by 6.47%. The combined use of soil and AAS proves to be a viable and sustainable method of waste utilization and carbon emission reduction in the construction industry, which provides a practical path towards carbon peaking and carbon neutrality.

“…It was also determined that geopolymer mortars produced with slag were important for durability properties. In their study by Bingöl et al (2020), geopolymer mortars produced using sodium metasilicate with three sodium concentrations of 4%, 8%, and 12% by mass were used in aggressive conditions (high-temperature, rapid chloride permeability, abrasion, and wetting-drying cycles). It was shown that high performance was achieved.…”

Today, geopolymer has an important place in producing sustainable alternative products by consuming less energy. This paper researches the elevated-temperature behavior of metazeolite (MZ) and slag (S) based geopolymer composites, reinforced by polyvinyl alcohol fiber (PVA) (at 0.3%, 0.6% and 0.9% by volume), and basalt fiber (B) (at 0.3%, 0.6% and 0.9% by volume). The curing was carried out at room temperature for up to 7 days and then the freeze-thaw test was applied as a curing method for up to 28 days. Slag was used alongside metazeolite to solve the problem of delayed setting time with its high Ca content. After 7 days, the damp environment provided by the freeze-thaw curing ensured the preservation of the compact structure and the continuation of geopolymerization. The resulting geopolymer composites were exposed to temperatures of 250, 500, and 750 oC. The flexural and compressive strengths, microstructure (FT-IR, XRD, SEM, TGA-DTA, and micro-CT analyzes), ultrasonic pulse velocity (UPV), visual inspection, and weight-losses of the geopolymers were examined to evaluate their behavior. According to the results, it was observed that geopolymer samples maintained their stability after 750oC. In this way, a sustainable geopolymer composite was produced by using less energy.
