Air-entraining agents enhance concrete durability against freeze–thaw damage; however, their development is labor-intensive and cost-prohibitive. This research implements a multilayer approach by incorporating three hierarchical layers: the molecular properties of nonionic surfactants (Layer 1), their physicochemical characteristics (Layer 2), and the air-entrained microstructural porosity of hardened cement paste (Layer 3). By integrating key molecular parameters—such as hydrocarbon chain length, hydrophobicity, and molecular weight—this model effectively predicts the air-entrained porosity of cement paste. An extensive experimental study was conducted to characterize the physicochemical and microstructural properties of 59 distinct nonionic surfactants. To the best of our knowledge, this represents the first comprehensive dataset of molecular and physicochemical properties of air-entraining agents reported in the literature. Moreover, no prior study has established such a detailed link between the molecular characteristics of nonionic surfactants and cement microstructure. This dataset served as the foundation for developing the predictive model, which demonstrated the feasibility of this approach in predicting the air-entraining performance of nonionic admixtures. The developed model facilitates the rapid screening of candidate surfactants and the optimization of their molecular structure while minimizing the need for extensive experimentation. Furthermore, distinct trends emerged from the dataset, offering new insights into the interdependent properties that govern air entrainment in cementitious materials.</p>","PeriodicalId":200,"journal":{"name":"Journal of the American Ceramic Society","volume":"108 12","pages":""},"PeriodicalIF":3.8,"publicationDate":"2025-08-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ceramics.onlinelibrary.wiley.com/doi/epdf/10.1111/jace.70148","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145196553","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, we investigate the structure and property relations of a series of novel bioactive phosphosilicate glasses through an integrated experimental and computational study by using characterization techniques such as magic angle spinning nuclear magnetic resonance (MAS NMR), neutron diffraction, and molecular dynamics (MD) computer simulations. Our results reveal that zirconia significantly alters the chemical environment surrounding silicon, as evidenced by ²⁹Si NMR, through the formation of Si–O–Zr linkages. This structural modification is further supported by shifts in partial pair distribution function peak positions toward longer distances for P–O and Si–O pairs, as observed in neutron diffraction data for glasses containing 4 mol% ZrO₂. Additionally, apparent depolymerization is observed around silicon, showing a decrease of Si Q⁴ and Q³ species with increasing ZrO₂. Phosphorus predominantly exists as Q⁰ (∼90%) and Q¹ (∼10%) species, showing little sensitivity to zirconia composition variations, as demonstrated by ³¹P NMR. Increasing the P₂O₅ content results in a more disordered and heterogeneous glass network, as neutron diffraction revealed. MD simulations indicate a preferential distribution of isolated orthophosphate units. The structural information from MD was employed to establish a quantitative structure–property relationship analysis with key physical properties, such as Young's modulus and density.
