Summary: This paper proposes a simple and robust additive solution to improve the water-resistance of clay materials by revisiting a traditional recipe. The combination of oak tannin with iron chloride is shown to enhance the rheological behavior, compressive strength, and water resistance of clay materials through complexation reaction between iron ions and tannin, preventing water ingression.

Summary: Intermediate Geomaterials (IGMs) are natural formation materials that have unpredictable engineering behavior between soils and rocks. The engineering properties of IGMs have been traditionally classified either as soils or rocks, leading to conservative or under-conservative designs. Laboratory and in-situ tests have been used to characterize IGMs, but both have limitations in terms of reliability and sampling constraints. This article reviews the tests used to characterize IGMs and explores the shear strength variation based on their geological origin.

Summary: This study aimed to extend the shelf-life of P. speciosa seeds and pods by using freeze drying and blanching as pretreatments. The freeze-dried samples had longer storability and higher rehydration ratio without significant degradation of nutritional value and overall acceptability. Blanching prior to drying or freezing helped preserve the nutritional value of P. speciosa. Freeze drying along with blanching was found to be effective in extending the shelf-life of P. speciosa without affecting its sensory profile.

Summary: Seed size is critical for the regeneration process of plant populations. Larger seeds of Khaya senegalensis showed higher germination rates, while smaller and medium-sized seeds of Parkia biglobosa performed better in terms of germination. However, larger seeds consistently produced more vigorous seedlings. Large seeds ranging from 0.25-0.37 g for Khaya senegalensis and 0.2-0.32 g for Parkia biglobosa are the most suitable for cultivation. Distributing these seeds can contribute to reforestation and agroforestry programs involving these species in Cote d'Ivoire. These findings support the sustainable management of these species and serve as a basis for forest regeneration policies.

Summary: Solid-state intercalation was successfully used to prepare organo-smectites with various cationic surfactants and natural clays. XRPD data showed an increase in the basal spacing of the unit cell of the smectite with the surfactant loading, indicating the penetration of surfactants into the interlayers. FTIR spectra demonstrated changes in the intensity of water bands and the appearance of new bands related to the surfactants' CH2 groups.

Summary: Thallium (I) was efficiently removed from aqueous solution using gamma-alumina nanoparticles as nano adsorbents. The adsorption process was optimized by varying experimental conditions such as adsorbent dose, agitation time, initial concentration, pH, and temperature. The results showed that the removal efficiency was highest at pH around 8, and the adsorption mechanism followed pseudo-second-order kinetics and Freundlich isotherm. Thermodynamic investigations revealed that the adsorption was spontaneous and exothermic, with physisorption dominating. The diffusion model suggested the involvement of both surface spread and intraparticle diffusion in the sorption process.

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.

Summary: Tailings dam break and leakage accidents pose a threat to the safety of people in mining areas and cause severe environmental pollution. 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.

Summary: Incorporation techniques of phase change materials in cementitious composites have a significant influence on thermal properties. This study investigated the thermal behavior of low-temperature PCM when subjected to varying temperature change rates and pore confinement inside the porous network of lightweight aggregates. The results showed that ramp rates affect the nucleation and crystallization growth process during the phase transition, and the pore structure of the aggregates affects the supercooling phenomenon and confinement pressure of the PCM.

Summary: This study investigates the fatigue behavior of concrete under different stress reversal conditions. The results indicate that stress reversal generally causes more severe damage and reduces the cycles to failure compared to tensile fatigue. Additionally, adding some level of compression contributes to the energy required for failure under stress reversal fatigue. Specimens with higher concentration of fractured aggregates achieve longer fatigue lives.

Summary: The susceptibility of building stones to fire and high temperature was investigated in this study by examining their physical and mechanical properties. The results show that both compressive and tensile properties of stones are affected by temperature changes. The tensile strength is particularly sensitive to temperature changes, requiring special attention to the components subjected to tensile stress in stone buildings. Principal component analysis was used to predict the mechanical properties of stones, providing a new method for calculating the residual mechanical properties after high temperature or fire.

Summary: This paper investigates the correlation between the friction coefficient and the surface roughness of concrete-to-concrete interfaces. Experimental tests were performed on specimens with different surface treatments, and the surface roughness parameters were analyzed and correlated with the shear strength and friction coefficient. The results showed that certain roughness parameters had a strong positive correlation with the friction coefficient, while others had little or no correlation. A novel combined roughness parameter with optimized correlation was proposed.
