Summary: Aluminum plays a role in the formation and structure of ASR products, with concentrations lower than 0.1 mM not preventing or altering the structure of ASR products formed at 40 degrees C. However, the formation of crystalline ASR products at 80 degrees C is reduced at higher aluminum content due to the formation of a zeolitic precursor.

Summary: This study investigates the macroscopic expansion caused by alkali-silica reaction (ASR) and its corresponding ASR products in OPC mortar specimens with boosted alkalis. The expansion increases with the concentration of inherent alkalis, with sodium-boosted samples expanding three times as much as potassium-boosted samples. ASR gels in aggregate veins are calcium-free and amorphous, and their atomic ratios are independent of alkali cations. Na-gel in aggregate veins is more hydrophilic and accounts for the larger expansion. Boosted alkali cations are more effective in ASR products formation than in exposing solution. A new observation is reported that NaOH exposure inhibits ASR in K-boosted samples.

Summary: Understanding the formation and behavior of Alkali-silica reaction gel (ASR gel) in cement pore solutions is crucial in mitigating concrete strength retrogression. Advanced atomistic simulations demonstrate how ASR gel formation in cement pores can damage the paste structure, with drying or calcification affecting its strength. The attraction of alkali ions released during calcification by the gel alters its interaction with cement pore walls, potentially leading to concrete damage.

Summary: Although lithium nitrate is used to mitigate the ASR in conventional cement systems, it is not effective in alkali-activated slag (AAS) mortars due to their high alkalinity and dense microstructure. Increasing the concentration of lithium nitrate does not further reduce the expansion of AAS mortars. The SEM/EDS analysis shows that ASR products are still present in AAS mortars even when exposed to a lithium nitrate solution for 56 days.

Summary: The paper investigates the tensile creep behavior of concrete with supplementary cementitious materials such as fly ash and ground granulated blast furnace slag. Experimental results show that the tensile creep of fly ash concretes is slightly lower than that of reference mixtures without SCM, while the higher the GGBFS content, the higher the tensile creep. Existing creep models cannot predict the experimental tensile creep results, thus a new tensile creep model is proposed.

Summary: This study examines the shrinkage properties of two sustainable aluminosilicate blends, namely fly ash and limestone-calcined clay (LC3). Paste and concrete samples were tested to determine the maximum replacement of binder while maintaining strength. The study analyzed the chemical and autogenous shrinkage of paste samples, and further investigated hydration using thermogravimetric analysis and Fourier transform infrared spectroscopy. By comparing different types of shrinkage, such as autogenous, drying, and total shrinkage, for concrete with specific compressive strength, the study found that LC3 exhibited higher autogenous shrinkage due to faster hydration compared to fly ash. Despite this, LC3 had lower drying shrinkage, making it a more sustainable and eco-friendly alternative to fly ash concrete when considering cement replacement levels, shrinkage, and ecological impact.

Summary: This research studied the effect of Mg replacing Al on the reaction kinetics and phase assemblage of sodium silicate-activated calcium-magnesium-aluminosilicate (CMAS) glasses. The calcium-aluminosilicate (CAS) glass exhibited faster reaction rate than CMAS glasses. Increasing the replacement level in the CMAS glasses slightly accelerated the reaction but significantly increased the total heat. The formation of katoite and stra spexpressioncing diexpressioneresis tlingite was observed at high Al2O3 wt% of 20 and 25, respectively. Thermo dynamic modelling and gas adsorption measurements supported the prediction of a decrease in the total volume of the hydrates. The outcomes of this study provide valuable insights for customising the mix design of alkali-activated binders for enhanced performance.

Summary: In this study, we analyzed representative FANET protocols under a multi-UAV-based reconnaissance scenario and found that AODV performed the best with an 81% PDR under the SRWP mobility model. When considering reconnaissance rate, SRWP showed excellent performance at 76%, while RDPZ and EGM models performed reasonably at 62% and 60% respectively. We also observed that increasing the number of nodes improved network connectivity but decreased the performance of the routing protocol, and the location of the ground control station influenced the PDR performance of the combination of routing protocols and mobility models.

Summary: This paper investigates the flexural tensile behavior and splitting tensile strength of PVA fiber-reinforced foam concrete, revealing the underlying mechanism of fiber influence on both pre-crack and post-crack behavior. Machine learning technology is utilized to develop regression models that describe the importance of design parameters, fiber distribution, and pore structure. The results show that PVA fibers significantly enhance the pre-crack flexural performance and splitting tensile strength of foam concrete, and this improvement is related to the effect of fibers on the pore structure.

Summary: This study investigates the early age cracking of limestone calcined clay (LC) blended concrete and mortar induced by restrained shrinkage. Ring tests were conducted on LC blended concretes with 44% GP cement replacement and reference GP cement-only concretes. The results show that LC blended concrete cracked earlier due to a high stress rate, which is influenced by the autogenous shrinkage. The dependency of cracking on early-age autogenous shrinkage was also confirmed by ring tests on LC blended mortar mixes with different replacement levels.

Summary: In this study, CBS glass/Al2O3 composites were developed for LTCC applications based on a CaO-B2O3-SiO2 (CBS) glass system with a high boron content. The study revealed that the softening of glass and interfacial reaction between the glass and Al2O3 were the two most important factors affecting LTCC's densification process. Real-time shrinkage rate of LTCC during sintering was successfully simulated, and it was proven that the formation of the CaAl2(BO3)O phase played a significant role in reducing glass viscosity and promoting dense structure formation. The resulting LTCC composite exhibited excellent performance for high-frequency applications.

Summary: In this study, the disordering caused by swift heavy ion irradiation in two different compositions of pyrochlore structures was investigated. X-ray diffraction, Raman spectroscopy, and high-resolution transmission electron microscopy were used to analyze the samples before and after irradiation. It was found that both compositions underwent amorphization due to irradiation, with a slower rate observed in Nd1.8Zr2.2O7.1. The irradiation-induced modified track region in Nd1.8Zr2.2O7.1 consisted of defect-rich pyrochlore structure, anion-deficient fluorite structure, and amorphous domains.

Summary: The study investigates the frictional and wear behaviors of carbon fiber-reinforced SiC ceramic matrix composites with different fiber orientations mating with ceramic balls. The results show that fiber orientation significantly affects the friction and wear properties of the composites. Pads with randomly arranged fibers demonstrate better friction stability and lower wear volume, potentially suitable for bearing material applications. The research also explores the factors influencing the formation of continuous tribo-film and identifies abrasive wear and oxidation wear as the dominant wear mechanisms for the friction pairs.
