Summary: The utilization of manufactured lightweight aggregates complicates the preparation of self-compacting concrete (SCC) in terms of cost and water-to-cement ratio calculation. This study proposes a modified method using black volcanic rock with vesicular texture to minimize water absorption and improve the bond between aggregates and the cementitious matrix. The optimized quaternary cementitious system, including silica fume, class F fly ash, and limestone dust, achieves the desired properties for structural lightweight concrete.

Summary: This study focuses on the production of low carbon footprint and lightweight refractory matrices with controllable pore structures, thermal stability, and low thermal conductivities. The results show that the produced matrices have low thermal conductivity values between 0.49 and 0.18 W/mK and exhibit thermal stability due to the formation of refractory crystalline phases. The materials provide energy-saving, lightweight ceramic foams with high strength and low thermal conductivities, making them potential candidates for refractory applications.

Summary: Thinner storage slabs can achieve higher power output and reduce charging/discharging time. The variation in heat transfer fluid flow rate has a greater impact on temperature distribution and energy efficiency when thicker slabs are used. The macro-encapsulation design does not significantly affect the discharging efficiency of the tank, which was around 85% in this study.

Summary: This paper investigates the deformation characteristics and damage evolution of six types of BPB composite samples under uniaxial compression conditions using a digital speckle correlation method. A new damage evolution equation is established based on the input strain energy and dissipated strain energy. The results show that deformation localization and macroscopic cracks occur at the coal-backfilling interface, then expand to the backfilling elements, and ultimately appear in the coal elements. The damage evolution curve and equation agree well with the test results, providing further understanding of the instability prevention and control mechanisms of the BPB composite samples.

The four concepts include buoyant force, submerged unit weight, seepage force, and critical hydraulic gradients. By comparing four typical GES expressions and their impacts on the definition of the four concepts, the results suggest their profound significance for geotechnical applications and the need for further validation.

Summary: FRP wrapping can improve the tensile strength of cement mortar-coal composite (CCC) by reducing the instability of the interface and modifying the failure pattern. The experimental and numerical simulation results show that FRP wrapping significantly enhances the nominal tensile strength of the specimens and reduces their anisotropy. Three types of failure modes are observed: tensile cracks in the coal and cement mortar elements, and shear or tensile fractures at the interface. FRP wrapping increases the damage degree of the coal and cement mortar elements in unstable specimens, but decreases the extent of damage at the interface.

Summary: As a reinforced composite material, alkali-resistant glass fiber-reinforced concrete (AR-GFRC) is widely used in large-scale projects due to its advantages such as strong corrosion resistance, high tensile and impact resistance, high elastic modulus, and low cost. However, the mechanical properties and optimal ratio of AR-GFRC in complex environments such as strong alkaline, along with their meso-damage and failure mechanism, have not been fully understood. In this study, the tensile performance, microstructure, and reinforcement mechanisms of AR-GFRC under alkaline environments were investigated through splitting tensile tests, scanning electron microscopy (SEM), and numerical simulations.

Through comparison with the polycrystalline diamond compact (PDC) bit, it was found that they have similar rock breakage mechanisms and force equilibrium. Cutting tests on granite, marble, and limestone were conducted to determine the relationship between rotary torque and applied thrust. Based on the test results and tool-rock interaction features, a theoretical FPI model of the disc cutter was derived and verified using field TBM performance data.

Summary: The use of the heavy hammer compaction method improves the bearing characteristics of underwater rubble-mound foundations, ensuring safety and stability in port and coastal engineering projects. This study combines image-recognition technology, 3D laser scanning technology, discrete element numerical simulation, and field testing to analyze the effects of various factors on the bearing characteristics of rubble-mound foundations. The main conclusions are: (1) The load-settlement curve of the foundation has three stages: rapid growth, slow growth, and failure. (2) The ultimate bearing capacity of the foundation is positively correlated with vibration time and amplitude, while riprap particle size and foundation thickness have minimal effects. (3) Settlement increases with increasing compactness when adjusting vibration time, amplitude, and foundation thickness, while factors like riprap particle size, gradation, and vibration frequency have less significant effects on compactness and settlement.

Summary: This study analyzes the erosion mechanisms of NaCl solution on asphalt concrete and finds that NaCl solution softens asphalt and promotes the intrusion of crystalline salt into it. Salt crystallization alters the surface roughness of aggregates, resulting in a decrease in skid resistance but an improvement in compressive strength. Additionally, the concentration of NaCl solution initially has no significant impact on the mechanical performance of asphalt concrete, but its domination gradually increases with the intensification of cyclic effects.

Summary: This paper investigates the effect of freezing and thawing cycles on the tensile behavior of cracked ultra-high performance concrete (UHPC). The results show that long-term freezing and thawing action deteriorates the cracking strength, tensile strength, tensile strain, and strain energy of cracked UHPC. On the other hand, the action of water generally favors the development of tensile properties of UHPC. The crack distribution tends to be unsaturated under freezing and thawing environment, and the re-hydration reaction is hindered. The pore structure near the crack varies under different environments.

This study focuses on solidifying tailing sand using microbial induced calcite precipitation (MICP) to improve strength and fix heavy metals. The curing time of MICP bio-cemented tailings is found to significantly impact the strength of tailings, while its effect on heavy metal fixation is minimal. The optimized MICP curing time is 10 days, resulting in improved strength and cementation of tailings particles.
