Geopolymer and alkali-activated materials formed by a chemical reaction between an alkaline activator solution and an aluminosilicate source have gained popularity in recent years. The alkaline activator solution dissolves the aluminosilicate source, which then undergoes a polycondensation reaction to form a three-dimensional geopolymeric gel network. The development of this network ensures the strength and durability of the material. Today, this phenomenon of durability has been studied in detail to enable the development of superior construction materials, taking into account degradation mechanisms such as carbonation, leaching, shrinkage, fire, freezing and thawing, and exposure to aggressive environments (chlorides, acids, and sulphates). Although there are many unsolved problems in their engineering applications, slag-based alkali-activated materials appear to be more advantageous and are promising as alternative materials to ordinary Portland cement. First of all, it should not be ignored that the cure sensitivity is high in these systems due to compressive strength losses of up to 69%. Loss of strength of alkali-activated materials is considered an important indicator of degradation. In binary precursors, the presence of fly ash in slag can result in an improvement of over 10% in compressive strength of the binary-based alkali-activated materials after undergoing carbonation. The binary systems can provide superior resistance to many degradation mechanisms, especially exposure to high-temperature. The partial presence of class F fly ash in the slag-based precursor can overcome the poor ability of alkali-activated materials to withstand high temperatures. Due to the desired pore structure, alkali-activated materials may not be damaged even after 300 freeze–thaw cycles. Their superior permeability compared to cementitious counterparts can extend service life against chloride corrosion by more than 20 times. While traditional (ordinary Portland cement-based) concrete remains the most widely used material in construction, geopolymer concrete’s superior performance makes it an increasingly emerging option for sustainable and long-lasting infrastructure.</p></div>","PeriodicalId":673,"journal":{"name":"Journal of the Australian Ceramic Society","volume":"60 3","pages":"885 - 903"},"PeriodicalIF":1.8,"publicationDate":"2024-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s41779-024-01011-z.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140587059","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The peak glass crystallization and depolymerisation temperatures of the glass–ceramics increased gradually with increasing MnO₂ content, and the main crystallization mode of the samples was one-dimensional crystallization. The main crystalline phase of the resulting glass–ceramics was transformed from diopside to spinel, with a crystallization temperature of 860℃. Heavy metals solidified in the spinel phase.

In this research, HA and rfGO were produced. HA-CS/Gel-rfGO nanocomposites with different HA values (200, 500, 800, and 1100 mg) were applied by electrophoretic deposition (EPD) at various voltages (80, 100, and 120 V). Analyzing HA and rfGO by XRD, SEM, and FTIR proved the successful synthesis. The contribution of HA and coating voltage was investigated on the morphology, microstructure, and corrosion behavior by morphological studies, electrochemical impedance spectroscopy (EIS), and potentiodynamic polarization. The possible intermolecular interactions between coating components were evaluated and found to be effective on the coating performance. Increasing HA reduced the cracks but caused unfavorable agglomerations and uneven distribution of the constituents in the coatings. Higher voltages caused voids and porosities. The coating at 1100-mg HA was porous but crack-free. The coating thickness increased by voltage and HA, from ~ 9.3 to 14.8 µm. Electrochemical polarization and EIS analysis in SBF solution showed that corrosion behavior is affected by coating morphology and bonding configurations among HA-CS/Gel-rfGO. The lowest corrosion rate occurred in the lowest HA (200 mg), with a corrosion resistance of 143,000 Ω.cm². At constant HA, increasing the applied voltage significantly decreased the corrosion resistance from 23,046 to 15,000 Ω.cm², and an induction bend occurred at 120 V.

Rutile and perovskite (CaTiO₃) phases were also found in TiO₂ added CHAs in addition to these phases.

It has been determined that grain growth and decomposition are the underlying factors in obtaining the highest density, hardness, fracture toughness and compressive strength values for CHA at different temperatures.
