Summary: The main aim of this article is to determine the effect of complex additives on the adhesive strength of ash-cement mortars. Through experimental-statistical models, it was found that optimal water-cement and ash-cement ratios, as well as the addition of superplasticizers, air-entraining and water-retaining additives, can significantly improve the adhesive strength. The study also shows that regrinding fly ash and increasing the cement-sand ratio have a positive effect on the adhesive strength of modified cement-ash mortars.

Summary: The study found that the type of cement does not affect water retention in plastering mortars, as it is regulated by cellulose ether. All mortars with the admixture had a water retention value of approximately 99%. The high water retention is closely related to the action of the cellulose ether admixture, confirming the possibility of using cement with additives for plastering.

Summary: Dry-mix mortars with PC-CSA binders modified by HEMC exhibit improved water retention ability, reduced flowability, increased air content, and prolonged setting time. However, HEMC may decrease flexural and compressive strengths in cement mortars with PC-CSA binders, while enhancing tensile bond strength. Additionally, HEMC affects the hydration process of the binders and alters the formation of certain compounds, resulting in changes in pore structure.

Summary: The foundry industry generates a large amount of waste, including not only foundry sands, but also other wastes with no known reuse solutions. This study aimed to incorporate paraffin waxes and ceramic mold shells into cement mortars and evaluate their impact on the physical and mechanical properties. The results showed a reduction in workability, water absorption, flexural and compressive strengths of the mortars. However, the mortars still exhibited satisfactory physical and mechanical behavior, indicating a potential practical application.

Summary: The lost wax foundry industry generates a large amount of waste, which is currently being deposited in landfills due to the lack of practical applications and challenges in recycling. This study demonstrates the potential of incorporating the industry's waste, such as ceramic mold shells and paraffin wax, as substitutes for natural aggregates in cementitious mortars for the construction sector. The results show that the mortars with waste incorporation exhibit adequate performance under normal operating conditions and freeze-thaw actions.

Summary: This study investigated mortars with varying amounts of recycled ceramic aggregate (RCA) to analyze the physical and mechanical parameters. The research found that an increase in RCA content led to a significant decrease in compressive strength, while changes in flexural strength were minimal. Additionally, the study revealed that the amount of RCA impacted the moisture absorption ability and thermal conductivity coefficient of the mortar.

Summary: Researchers have successfully fabricated composite hydrogels with high strength, toughness, and adhesion by a simple composite strategy. The composite gels are reinforced by a fiber fabric matrix, providing high load-bearing capability and good crack resistance. Additionally, the gel matrix exhibits good adhesion due to its soft and sticky nature. The effect of fiber fabric content on the mechanical and adhesion properties of the composite gels has been systematically studied, resulting in an optimized composite gel with significantly improved properties compared to the gel matrix.

Summary: This study analyzed the electrical properties of cement mortar with graphene oxide (GO) and nanofibrillated cellulose (NFC) using an equivalent impedance circuit. The results showed that the addition of nanomaterials affected the electrical resistance of the high-frequency arc and matrix porosity, which in turn influenced compressive strength. The findings suggest that impedance spectroscopy is a useful tool for monitoring the curing process and microstructure evolution of cementitious composites with nanoreinforcements.

Summary: The study shows that the mechanical strengths and drying shrinkage of cement mortars change with the content of HEMC, with a certain level of control within a certain range. HEMC significantly impacts the hydration rate of cement pastes, but has a minor effect on the late hydration degree. Furthermore, the addition of HEMC alters the pore structure of cement mortars.

Summary: In this study, laser surface texturing (LST) was performed on the surface of 6061 aluminum alloy using a pulsed laser, and then SHF-2D zinc epoxy coating (SP) was applied. The results show that LST can effectively increase the adhesion strength, and the pattern of the spatter produced by laser irradiation determines the adhesion strength.

Summary: The technique of surface photoactivation using VUV light has been used for adhesive-free bonding of POM plates. The POM surfaces were modified through VUV light irradiation, resulting in the formation of oxygen-containing functionalities. The bonds formed through thermocompression and the mechanical properties of the bonding interface were different from the bulk POM.

Summary: The paper focuses on the behavior of glued joints of wooden sections at elevated temperatures. The study found that the curing of PRF and PUR adhesives was insufficient at high temperatures. At 140℃, there was no significant reduction in strength for all tested adhesives, but a longer duration (1 day) led to a decrease in tensile shear strength. At 170℃, PRF and EPI showed a significant drop in strength, while PUR lost its strength completely after longer duration exposures.

Summary: Polyurea coated structures have garnered significant attention due to their various applications. However, there is a lack of research on delamination in polyurea coated structures. This study aims to develop a rate-dependent traction-separation model and a numerical modeling framework to simulate the rate-dependent delamination process. The proposed approach successfully reproduced the fracture mechanisms and aided in understanding the interaction between different regions during delamination.
