Abstract ：
Magnesium-silicon-based cement (MSC) is a novel construction material composed of light-burned magnesium oxide powder and various siliceous raw materials, offering significant low-carbon advantages. However, the types and elemental compositions of raw materials introduce substantial uncertainty into the mechanical properties of MSC, making it challenging for traditional experimental methods to predict its performance accurately. Machine learning (ML) techniques hold considerable benefits in dealing with complex relationships. This study aimed to use ML techniques to establish a predictive model for the compressive strength of MSC and explore the impact of different feature parameters on the compressive strength of MSC through an interpretable model. The results demonstrated that the Extreme Gradient Boosting (XGB) model excelled in prediction accuracy. Among all feature parameters, curing age was the most crucial factor influencing the compressive strength of MSC. Element content analysis indicated that there was a nonlinear relationship between the compressive strength of MSC and the proportions of silicon (P_Si) and magnesium (P_Mg). The ideal optimal Mg/Si ratio was approximately 0.76. Furthermore, the analysis of interactions between elements showed that nearly balanced contents of Mg and Si produced a positive interaction effect which contributed to improving the mechanical properties of MSC. Al, Ca, and Fe exhibited significant variations in their influence on the Mg-Si interaction across different content ranges, presenting clear regional dependencies and element-specific effects.

Abstract ：
Concrete pumping technology is widely used in reservoirs, dams, harbours and other hydraulic structures. To investigate the effects of pumping on the flowability, mechanical strength and frost resistance of hydraulic concrete, long-distance pumping tests were carried out on self-compacting concrete (SCC). This paper investigated the influence of high-pressure pumping on the workability, mechanical strength and frost resistance of SCC by analysing the changes in various properties of SCC before and after long distance pumping. The flowability of the fresh concrete decreased after long-distance pumping. Compared to before pumping, the slump of the four groups of SCC decreased by an average of 3.93% and the slump-flow decreased by an average of 23.09%. The homogeneity and stability of the fresh SCC improved significantly after pumping. After pumping, the V-funnel time of SCC was reduced by an average of 82.32% and the segregation rate was reduced by an average of 125.76%. Additionally, there was a slight increase in mechanical strength indicated by an average increase of 5.87% in cubic compressive strength, 8.99% in axial compressive strength, 7.78% in tensile splitting strength, and 5.22% in modulus of elasticity. Notably, the frost resistance of the SCC showed significant improvement after pumping. Under non freeze-thaw conditions, the compressive strength of SCC after pumping increased by an average of 5.87%. After 200 freeze-thaw cycles, the compressive strength (after pumping) increased by an average of 12.46%. An air void analyser was then used to test the air-void parameters to analyse the effect of long-distance pumping action on the air voids parameters. The study further established the correlation between air-void structure characteristics and freeze-thaw resistance. Under freeze-thaw conditions, the compressive strength showed a linear correlation with air content and spacing factor. The process of pumping can enhance the air-void structure of SCC, leading to improved frost resistance. Therefore, in the design of concrete frost resistance, pumping can be considered as an influencing factor to improve the frost resistance of concrete.

Abstract ：
The thorough investigation into the evolution of concrete performance under sulfate attack environments holds significant importance for engineering applications in specific conditions. In this paper, a prediction model for the two evaluation indexes of sulfate attack resistance of concrete (SARC), namely compressive strength corrosion resistance coefficient and mass loss rate, is established based on four machine-learning algorithms: Support Vector Regression, Random Forest Regression, Gradient Boosting, and Extreme Gradient Boosting (XGB). A comparison of the various performances showed that the model based on the XGB algorithm had the strongest generalization ability and offered the best prediction of SARC (K test set R2=0.963, MLR test set R2=0.903). Feature importance and partial correlation analyses were performed for the two XGB models separately, and a graphical user interface was designed based on the two predictive models. The results reveal that the number of cycles, water-binder ratio, and cement content significantly influence the SARC. Moderately increasing cement, fly ash, and coarse aggregate content can enhance the SARC. Increasing the number of cycles, drying time, water-binder ratio, sand, and solution concentration will reduce the SARC. Therefore, measures such as moderately increasing the amount of cement, reducing the water-binder ratio, and increasing the fly ash content can be increased to improve the SARC, but overuse has no significant effect.

Abstract ：
The effects of different contents of silica fume (SF) on the electromagnetic transmission performance (ETP) and mechanical properties of calcium aluminate cement (CAC) paste were studied. The dielectric loss of the main hydrated phases in the CAC paste was compared and analyzed for the first time by synthesizing various phases, and the electromagnetic transmission mechanism of SF in the CAC paste was explored. The results show that after adding SF, the porosity and pore tortuosity of CAC paste decrease, C(2)ASH(8) is densely packed in the pores, and long-term strength is significantly improved. With the increase of SF content, the dielectric constant and loss tangent decrease, and ETP becomes better. When the SF content is 30%, the ETP is increased by 40.51%, and the 90d compressive strength is increased by 18.50%. The degree of electromagnetic wave loss in CAC paste from large to small is: C(3)AH(6) > AH(3) > C(2)AH(8) > C(2)ASH(8) > CAH(10) > CA and CA(2). Finally, the reasons for the improvement of long-term strength and ETP of CAC paste by SF were comprehensively elucidated from the aspects of crystal content, pore structure, and microstructure through a variety of microscopic test methods. This SF-CAC composite material is expected to be used in the basement or the partition wall of the house to enhance the signal of electronic devices, such as mobile phones in the above places.

Abstract ：
In urban areas with many buildings, the transmission of 5 G signals can be greatly absorbed or reflected, leading to decreased effectiveness of transmission. To address the issues mentioned above, the functional admixture formed by the mixture of nanocrystalline cellulose (NCC) and diammonium hydrogen phosphate (DAP) is added into concrete in this study, the electromagnetic transmission performance (ETP) and mechanical properties of concrete are enhanced simultaneously for the first time, and the electromagnetic transmission coefficient of concrete is doubled. When NCC and DAP are mixed, the electromagnetic transmission coefficient of concrete improved by 117.65 %-124.35 %, among which, when 0.5 wt% DAP and 4 wt% NCC are mixed, the electromagnetic transmission coefficient of concrete is the highest, and some frequency bands are as high as 70 %, meeting the requirements of electromagnetic wave transmitting materials. In addition, the compressive strength of concrete containing 4 wt% NCC and 0.5 wt% DAP increases by 24.3 % compared to concrete containing only 4 wt% NCC.

Abstract ：
Phosphogypsum slag-based composite cementitious materials were prepared by using phosphogypsum and slag powder as the main raw materials, adding quicklime, lithium slag, steel slag and other admixtures, and adding NaOH, NaHCO3 and triethanolamine (TEA). The effects of different admixtures on the fluidity, setting time and compressive strength of the composite cementitious materials were studied. Finally, XRD, MIP, TG-DTG, and SEM microscopic tests were used to analyze the reasons for the performance changes caused by the admixture from the aspects of phase composition, pore distribution, and hydration product morphology. The results show that the addition of NaOH, NaHCO3 and TEA reduces the fluidity and strength of the material and improves the setting time. The paste with 1 % NaOH and 0.03 % TEA can balance the working performance and mechanical properties.
