Abstract ：
Natural biobased materials, which can be obtained from crustacean exoskeletons, angelica sinensis, vanilla beans, amino acids, etc., have significant potential as eco-friendly corrosion inhibitors. In this study, several eco-friendly materials (chitosan (CTS), ferulic acid (FA), cysteine (Cys), and methionine (Met)) were proposed as corrosion inhibitors to improve the corrosion resistance of steel. Their inhibition effects and mechanisms in simulated concrete pore (SCP) solution were evaluated by electrochemical, surface measurements, quantum chemical (QC) calculations, and molecular dynamics (MD) simulations. The results showed that these inhibitors effectively improved the corrosion resistance of steel, especially for CTS (with a maximum inhibition efficiency of 92.6%). The adsorption of these inhibitors followed Langmuir and Freundlich adsorption isotherms, revealing the physical-chemical mixed adsorption modes. Surface characterization techniques revealed that the protective layers formed by these inhibitors could effectively inhibit the corrosion of the steel. QC calculations and MD simulations further confirmed the experimental results. Performance of cement mortar measurements revealed that these four inhibitors exhibited no effect on the workability of fresh mortar and improved the strength of mortar specimens, with a maximum increase in the compressive strength of 11.18%. This study is of great significance to improving the durability of reinforced concrete in the future.

Abstract ：
In this study, three hydration heat controlling materials (HHCMs), respectively, containing pure hydroxyl (polyvinyl alcohol, PVA), carboxylic (polyacrylic acid, PAA) and ester groups (maleic acid-ethylene glycol ester, P(MA-EG)) were synthesized and mixed with cement-based materials, and the hydration heat and setting time of cement pastes and the SEMI adiabatic temperature rise and strength of mortars were tested. The results showed that PAA and P(MA-EG) reduced the peak value of hydration exothermic rate by 77.45% and 62.28%, respectively, and prolonged 54.14 h and 15.56 h, respectively. Mechanism studies showed that HHCMs containing carboxylic or hydroxyl groups adsorbed on cement particles by Ca2+ complexation, while HHCMs containing ester groups hydrolyzed to carboxylic groups in alkaline cement pastes, which hydrolysis rate changed with the hydration temperature of cement-based materials to regulate the hydration process. This study aims to provide technical feasibility and theoretical basis for exploring new avenues of synthesizing HHCMs with different functional groups.

Abstract ：
In this study, the aluminum sulfate and industrial aluminum mud solid waste were respectively used to prepare shotcrete accelerators (named as AFA and AFS, respectively). A comparative analysis of their performance was conducted, and the underlying mechanisms were investigated. Different concentrations of sulfuric acid (25 %, 30 %, 35 %, 40 %, 45 % 50 % respectively) and liquid to solid ratios (2:1, 3:1, 4:1, 5:1, 6:1) were employed for the acid leaching of aluminum mud, among which 35 % mass concentration of sulfuric acid and 3:1 of liquid to solid ratio were identified as the optimal conditions according to the setting and hardening performance of cement. AFS exhibited superior effectiveness on enhancing the rapid setting and early age strength in cement pastes and mortars compared to AFA. The working mechanisms of AFA and AFS were revealed via the examination of ionic concentrations and pH values in pore solution, as well as the evolution of hydration heat and hydration products during the hydration process. The results showed that AFS generated higher concentration of Al 3 + and SO 4 2- ions during hydration as compared to AFA thus promoted the formation of a larger amount of ettringite. Moreover, the introduction of both AFA and AFS into cement pastes significantly lowered the pH values in pore solution, and AFS was more obviously, which accelerated the cement hydration process. This study presents an innovative approach in utilizing industrial aluminum mud solid waste for the development of a novel accelerator with promising performance characteristics, opening up new opportunities for its wide range of application.

Abstract ：
In order to quantitatively study the influence of the weakening of the disconnectable coupling joint (DC joint) on the retaining structure, the pre-axial force retention performance of the steel support, the axial force of the steel support, the horizontal displacement of the diaphragm wall, and the ground settlement around the foundation pit were monitored during the construction of the foundation pit. The evolution process of the monitoring data was analyzed, and the corresponding numerical model verified by the monitoring data was established. The influence of the yield load of the DC joint, the initial compression stiffness, and the weakening of the pre-axial force on the stability of the retaining structure was studied by numerical simulation. The results show that the pre-axial force of steel support is only 67% of the design value when the soil below is not excavated within 24 h. The DC joint has a significant weakening effect on the steel support, which is unfavorable for the stability control of the foundation pit retaining structure. The pre-axial force and initial bending stiffness have a great influence on the stability of the retaining structure. When the yield load is not lower than that of the row piles, the DC joint has no effect on the stability of the retaining structure. This model can predict and analyze the deformation trend under different working conditions to a certain extent, providing certain reference value for safety plans during construction.

Abstract ：
Although the side chain ionizability (the adsorption group density and adsorption space are changed) of polycarboxylate superplasticizer (PCE) serve as the key structural parameter in affecting the cement hydration, its effect on cement hydration is unclear. Based on PCE with nonionizable side chain (NSC-PCE) and the PCE with ionizable side chain (ISC-PCE), the influence of the side chain ionizability of PCE on the hydration behavior of cement was studied. Compared with NSC-PCE, ISC-PCE has a stronger ability to change the migration of water and ions, thus delaying the crystal nucleation and growth of cement hydration (better morphology and distribution, the crystal size was reduced by more than 20 %), increasing the crystal growth index (tendency toward spherical growth), prolonging the phase boundary reaction (reduce micro-cracks), which was conducive to the formation of more uniform and dense crystals (good strength, ISC-PCE: 50.0 MPa > NSC-PCE: 49.2 MPa > Blank: 48.7 MPa). These findings provide the design basis and theoretical guidance for the innovative development of PCE.

Abstract ：
This study aims to achieve further progress in application performance of polymers in cementbased materials. The objective is to establish the research direction of superplasticizers with ordered micro-sequence via the innovation of synthesis technology and to clarify the correlation between the specific motifs in the microstructures of superplasticizers and the properties of cement pastes. In this study, a novel comb-like polycarboxylate superplasticizer (PCE) was synthesized using isobutenyl polyethylene glycol (IPEG) and hydroxyethyl acrylate (HEA) by atom transfer radical polymerization (ATRP) (defined as A-CPCE). Comb-like PCE with the same molecular weight as A-CPCE was also produced via conventional free radical polymerization (defined as CPCE). The molecular properties of both polymers and the structural motifs of monomers therein were characterized via size exclusion chromatography (SEC), H-1 nuclear magnetic resonance (H-1 NMR), C-13 nuclear magnetic resonance (C-13 NMR) and MATLAB, and furthermore the adsorption behavior of PCE polymers on cement particles was analyzed. Together with the rheological and mechanical properties of cement-based materials, the relationship between micro-sequence distribution and macro-performance of PCEs was investigated. The results showed that the monomer sequence distribution in A-CPCE was AAE and AAA, and the probability of the acid-ether ratio of 4:1 was 16.54%, meaning that relatively uniform polymer species were obtained. The A-CPCE molecules exhibited the smaller hydrodynamic radius (R-h=11.7 nm) and stronger adsorption capacity (maximum was 2.3618 mg center dot g(-1)) in cement pastes, which was in good accordance with Langmuir isotherm model and pseudo-second order kinetic model. The dispersing power of PCEs correlated with the specific motifs in the microstructures, thus indicating that A-CPCE enhanced the rheological performances of cement paste and concrete. In addition, the compressive strengths of concrete containing A-CPCE after 3 d, 7 d and 28 d were 16.00 MPa, 28.30 MPa and 52.9 MPa, respectively, which were significantly higher than those of concrete with CPCE.
