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 ：
Biochar is a promising carbon-negative supplementary cementitious material (SCM). However, traditional biochar lacks active ingredients, and its porous structure severely weakens the mechanical properties of ordinary Portland cement (OPC), limiting its substitutability in cement. To meet the dual needs of decarbonization and strength in cement, this paper explored the potential of two types of silica-rich biochar, rice husk biochar rich in amorphous silica and bamboo biochar rich in crystalline silica, as carbon-negative SCMs. Here, the hydration, microstructure, and mechanical properties of rice husk biochar and bamboo biochar blended cements were investigated. Similar to bamboo biochar, rice husk biochar reduces flowability and drying shrinkage due to its porous structure. However, rice husk biochar contains a large amount of amorphous silica, resulting in the promotion of hydration of clinker and a significant pozzolanic effect, which shortens the setting time of cement, improves the weak structure and bonding interface of biochar, and further increases the hydration degree and polymerization degree of calcium silicate hydrate. Compared with bamboo biochar, rice husk biochar blended cement exhibited significantly higher compressive strengths at the same substitutions and ages. A 5% rice husk biochar blended cement at 28 days exhibited 12.9% and 29.8% higher compressive strength than OPC and 5% bamboo biochar blended cement, respectively. The compressive strength of 10% rice husk biochar blended cement was only 4% lower than that of OPC at 28 days. From a life cycle assessment, 10% rice husk biochar blended cement has the lowest unified carbon emissions (per MPa), 22% and 28% lower than that of 10% bamboo biochar blended cement and OPC, respectively, showing great potential for lower unified carbon emission cementitious materials.

Abstract ：
In this study, a viscosity-reducing polycarboxylic acid superplasticizer (VRPCE) was synthesized using methylallyl polyoxyethylene ether (HPEG), acrylic acid (AA), and maltodextrin maleic acid monoester (MDMA) as the main raw materials. The influences of the VRPCE on the microscopic properties of cement paste were studied by gel permeation chromatography (GPC), total organic carbon test (TOC), zeta potential, laser particle size analysis, XRD, MIP, TG, and SEM. Finally, the effects of the VRPCE on the macroscopic properties of cement mortar were evaluated through flow time, slump flow, compressive strength, shrinkage, and creep. The results showed that the VRPCE can improve the hydration degree of the cement, optimize the pore structure, increase the porosity, improve the fluidity, compressive strength, and creep, and decrease the shrinkage resistance of the cement mortar.

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.
