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 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 ：
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 ：
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 ：
In this paper, star-like polycarboxylate superplasticizer (SPCE) and comb-like polycarboxylate superplasticizer (CPCE) were prepared via atom transfer radical polymerization (ATRP) to study the mechanism of the effec-tiveness enhancement resulting from this transformation of topological structure. It was found that SPCE mol-ecules acted higher adsorption amount and more Ca2+ complexes, and formed a lower and more compact adsorbed layer and larger surface coverage with a flat conformation on cement surface, depending on more anchored points per unit volume. Through this mechanism, cement particles adsorbed by SPCE showed stronger dispersible capability and colloidal interaction forces (the steric force was dominant), resulting in lower yield stress and plastic viscosity of the cement paste containing SPCE which behaved as an ideal Bingham fluid. The aim of this study is to clarify the mechanistic correlation between topological structure evolution and effec-tiveness promotion for PCE.

Abstract ：
In this study, two types of liquid alkali-free accelerators were prepared by aluminum sulfate (AF(1)) and aluminum mud wastes (AF(2)), and the life cycle assessment (LCA) in the preparation of AF(1) and AF(2) was compared. The LCA was considered from cradle to gate including raw materials used, transportation, and accelerator preparation based on the method ReCiPe2016. The results indicated that AF(1) had a higher environmental impact in all midpoint impact categories and endpoint indicators than that of AF(2), and AF(2) reduced 43.59% emission of CO2, 59.09% emission of SO2, 71% consumption of mineral resources, and 46.67% consumption of fossil resources than that of AF(1) respectively. As an environment-friendly accelerator, AF(2) had a better application performance than traditional accelerator AF(1.) When the dosage of accelerators was 7%, the initial setting times of cement pastes containing AF(1) and AF(2) were 4 min 57 s and 4 min 04 s respectively, the final setting times of cement pastes containing AF(1) and AF(2) were 11 min 49 s and 9 min 53 s respectively, and the compressive strengths at 1 d of mortars containing AF(1) and AF(2) were 7.35 MPa and 8.33 MPa respectively. This study aims to provide technical feasibility and environmental impact assessment for exploring new avenues of preparing environment-friendly liquid alkali-free accelerators with aluminum mud solid wastes. It has great potential in reducing carbon and pollution emissions and has a greater competitive advantage due to great application performance.

Abstract ：
Chemical admixtures are indispensable functional ingredients in modern construction, and their raw materials for synthesis are mainly sourced from petrochemical products, leading to petrochemical resource consumption and environmental damage. Using biomass as a raw material for preparing chemical admixtures for concrete is an effective and environmentally friendly method that holds great promise for overcoming these environment problems and obtaining exceptional application properties. This work systematically addresses the recent research advances in chemical admixtures using polysaccharide, polyphenol biomass and biorefineries, including their preparation methods, application effects and environmental impact assessment. The results show that the molecular structures of polysaccharide and polyphenol biomass contain a large number of active functional groups, which help bio-based chemical admixtures to be prepared by acylation, sulfonation and/or graft copolymerization, significantly improving the dispersibility, water retention, retardation, anti-adhesion and durability of cement-based materials. Also, the use of biorefinery technology endows chemical admixtures with superior environmental performance. In addition, this review addresses the importance of the life cycle assessment (LCA) method in evaluating the environmental impacts of bio-based chemical admixtures and establishes that environmental pollution can be substantially minimized by optimizing the preparation process (e.g., use of renewable raw materials, adoption of biorefineries, etc.). This article gives an overview on bio-based chemical admixtures and their high-value utilization and ecological development that provide a theoretical basis for the design of energy-saving and low-cost bio-based chemical admixtures.
