For steel fiber concrete, the relatively high 14-day mechanical properties belong to the 40 kg/m³ addition, with a compressive strength of 99.1 MPa and a bending strength of 18.5 MPa. The optimal addition of both basalt and carbon fibers is 3 kg/m³. For basalt fiber modified concrete, its 14-day compressive strength and bending strength are 111.1 MPa and 18.6 MPa respectively, and that for carbon fiber are 110.6 MPa and 18.2 MPa. Basalt fiber mainly reinforces concrete by its fracture energy, leading to brittle failure of specimens; whereas carbon fiber mainly relies on fiber pull-out to restrain the transverse expansion deformation of concrete, resulting in ductile failure of specimens.

The results of rheological tests showed that the addition of nanoparticles decreased the flowability of SCC. The results of the density showed that the sample containing 4 wt% of MgO processed in the water environment had the lowest density and the sample processed in the CO₂ environment had the highest density. In the samples containing SiO₂ nanoparticles, an increase in density was observed with the increase of SiO₂ nanoparticles in both cases. It was also determined the amount of heat released for the samples with nano MgO was higher than the samples with nano SiO₂, which can be attributed to the heat of the hydration reaction of MgO or the formation of calcium carbonate. The mechanical properties of the samples were investigated. The compressive strength significantly improved after the addition of MgO/SiO₂ nanoparticles. However, this improvement was more remarkable in the case of post-treatment with CO₂ compared to the samples fabricated with water. SEM results showed that the samples treated under CO₂ gas had irregular and needle-like morphology. The samples prepared by normal processing had CaCO₃ and SiO₂ phases, whereas the ones fabricated under CO₂ gas contained CaCO₃, SiO₂, and Ca(OH)₂. With the addition of nano MgO, the density of concrete decreases in the samples post-treated with water, whereas it increases for the samples post-treatment with CO₂ gas.

In this work, the aging tests consisting of 80 hot-rain cycles and 8 months of natural aging were carried out on foam ceramics. Special attention was paid to their compressive strength, tensile strength, compressive modulus of elasticity, bonding tensile strength, and bonding shear strength. The results revealed that the compressive strength and tensile strength of foam ceramics were not significantly affected by aging. Moreover, the bonding shear strength between ceramics and adhesives has drastically increased, while that between adhesives and cement has dropped, indicating the damage risks of the interface. Besides, the acceleration rate of the bonding tensile aging strength of foamed ceramics was found to be 12.16, while that between adhesives and cement was 5.44. The findings of this research provide the innovative experimental data on the aging of foam ceramics, but also inspiration for further study of artificial aging acceleration rate.</p></div>","PeriodicalId":673,"journal":{"name":"Journal of the Australian Ceramic Society","volume":"61 2","pages":"615 - 636"},"PeriodicalIF":1.8,"publicationDate":"2025-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143892706","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Four composites were fabricated using the Spark Plasma Sintering (SPS) method at 2000 °C with a 15-min holding time and a pressure of 30 MPa. Relative density, hardness, and fracture toughness were measured by Archimedes’ principle, micro Vickers hardness testing, and crack length measurement, respectively. Microstructural investigations and phase identification were also evaluated by Field Emission Scanning Electron Microscopy (FESEM) and X-ray Diffraction (XRD). The results indicated that during sintering, all ZrO2 reacts with B4C, leading to the in-situ synthesis of the new ZrB2. Thermodynamic evaluation revealed the synthesis temperature decreases by approximately 100 °C in the presence of C.B_n/GO/Gr additives. The highest relative density (99.4%) was obtained in the sample containing C.B_n. The introduction of ZrO2 and C.B_n/GO/Gr additives resulted in a decrease in the hardness of B4C decreases. The highest fracture toughness (5.7 MPa m^0.5) was obtained in the sample containing GO, while the lowest was observed in the sample without C.B_n/GO/Gr additive (3.9 MPa m^0.5).

The search for novel antibiotics and their introduction into the pharmaceutical industry are very difficult tasks. Consequently, it is crucial to develop novel approaches to combat bacterial resistance and stop bacteria from becoming resistant. Although ferrites and zinc oxide are widely used in mechanical, chemical, and electrical engineering, little is known about their potential as biomaterials. The goal of this work was to synthesize a novel antibacterial composite containing ZnFe₂O₄ and ZnO doped by Ho. A vibration sample magnetometer (VSM), field emission scanning electron microscopy (FESEM), and X-ray diffraction (XRD) were used to characterize the produced antibacterial. The crystallite size of prepared sample is calculated to be 16.7 nm, as shown by X-ray diffraction (XRD). The images from the field emission scanning electron microscope (FESEM) depict the samples’ morphology. The platelets in the sample are spherically formed and have a hexagonal shape. The micrograph is not consistent. VSM shows that the studied nanoparticles exhibit paramagnetic behavior. The effective magnetic moments were found to have been 0.14µ_B. The optical band gap (E_g) was measured to be 2.3 eV. Intermolecular interaction raises the refractive index of the nanocomposite, while interfacial polarizations and widening band gaps at the conductor-insulator interface are responsible for its high optical conductivity. When the nanocomposite was tested against both gram negative bacteria like K. pneumoniae and E. coli, Gram positive bacteria like S. aureus and B. subtilis as well as the fungal species C. albicans.
