“…In fact, the degree of heterogeneity of soil pores is related to the pore size. As evidenced by Zhang et al 21 the degree of heterogeneity of smaller pores is smaller than that of larger 38 pores. When the pore size is small enough, it can even be considered a uniform capillary, which is why the hysteresis behavior disappears after the matric suction is greater than a certain value.…”

“…Moro and Böhni 20 suggested that the ink-bottle effect is the main contributor to the hysteresis observed in the extrusion-extrusion curves in IEC-MIP. Recently, Zhang et al 21 conducted IEC-MIP experiments to explore the fluctuations in the ink-bottle effect within cemented materials, with a focus on pore size. Their study revealed a notable reduction in the ink-bottle effect as the pore size decreased.…”

“…Quantitative investigation of the ink‐bottle effect relies on measuring the changes in pore body and pore throat volume versus pore size. In laboratory experiments, the intrusion–extrusion cycle mercury intrusion porosimetry (IEC‐MIP) is a commonly employed method to quantitatively examine the ink‐bottle effect in porous media 17,20,21 . As the applied pressure increases during the intrusion, mercury intrudes into the smaller pore spaces.…”

The ink‐bottle effect, resulting from the heterogeneous pore structure, plays a significant role in the hydraulic hysteresis of water retention behavior. Experimental evidence indicates that volumetric deformation extensively influences the hysteresis characteristics of the soil‐water retention curve (SWRC). This paper presents a physical–based model that aims to simulate the contraction of the hysteresis loop in the SWRC during soil compression by considering the evolution of the ink‐bottle effect. Within the proposed model, it is assumed that the suction increment is consumed in two distinct manners: to overcome the ink‐bottle effect and to alter soil saturation. As soil undergoes compression, the ink‐bottle effect weakens, resulting in a reduced proportion of suction consumed in counteracting this effect. To quantitatively describe the impact of ink‐bottle effect evolution on SWRC hysteresis, a novel concept known as hysteresis potential is introduced, which is defined as the difference in natural logarithmic values of suction between the drying and wetting curves at a given saturation. Finally, the proposed model was validated using five sets of experimental data, affirming its capability to capture the hysteresis loop evolution in SWRC attributed to the weakening of the ink‐bottle effect during soil compression.

“…Calcium silicate hydrate (C-S-H) is the dominate material of Portland cement, which determines the overall properties of final structures [ 1 , 2 , 3 , 4 , 5 ]. Therefore, modifying the micro–nanostructure of C-S-H is one effective solution to enhance and functionalize the construction materials.…”

Mechanical Properties Evaluation of Polymer-Binding C-S-H Structure from Nanoscale to Macroscale: Hydroxyl-Terminated Polydimethylsiloxane (PDMS) Modified C-S-H

Exploring and modifying the C-S-H structure at a micro–nano level is an effective solution to improve the performance of Portland cement. Compared with organics inserting C-S-H, the research on the performance of a polymer-binding C-S-H structure from nanoscale to macroscale is limited. In this work, the mechanical properties of a modified C-S-H, using hydroxyl-terminated polydimethylsiloxane (PDMS) as the binders, are evaluated. The PDMS-modified C-S-H structures are introduced into macro-defect-free cement to obtain stress–strain curves changes at a macro scale. The AFM–FM was adopted to measure the morphology and elastic modulus of C-S-H at a nano scale. The molecular dynamics (MD) simulation was performed to assess the toughness, tensile properties, and failure mechanism. The results show that the PDMS-modified C-S-H powders change the break process and enhance ductility of MDF cement. The elastic modulus of PDMS-modified C-S-H is lower than pure C-S-H. When PDMS molecules are located between the stacking crystal units, it can enhance the toughness of C-S-H aggregates. The PDMS-modified C-S-H stacking structure has better plasticity, and its tensile strains are higher than the pure C-S-H. PDMS molecules hinder the initial crack expansion, leading to the branching of the initial crack. In addition, the measurement of AFM–FM can identify and obtain the mechanical properties of basic units of C-S-H. This paper enhances the understanding of cement strength sources and modification methods.
