Abstract

An innovative method is proposed in this study that combines long sequence precision prediction model with experiments to study how early hydration affects ultra-low water-binder ratio cementitious composite (ULWBRCC) properties. To be specific, by using heat release and degree of hydration as variables and introducing various temporal models to analyze the early hydration process, the micro- and macroscopic properties of specimens at different ages are assessed in detail. The obtained results can be summarized as follows: The long-sequence accurate time series model can predict the earliest hydration process of underwater ULWBRCC, and the predicted late-stage hydration pattern matches the experimental results. The underwater environment optimizes ULWBRCC's hydration process and increases its early compressive strength by 19.6%. The hydration of ULWBRCC is predicted using a time series model in the paper, filling the gap of uncertainty in the earliest performance of underwater rapid repair cement-based composite materials, and the MSE of the Informer is improved by 92.88% compared with other models.

阐明水下环境下超低水化比胶凝复合材料的早期水化过程

本研究提出了一种创新的方法，将长序列精度预测模型与实验相结合，研究早期水化对超低水胶比胶凝复合材料（ULWBRCC）性能的影响。以放热量和水化程度为变量，引入多种时间模型分析早期水化过程，详细评价了不同龄期试件的微观和宏观特性。结果表明：长序列精确时间序列模型可以预测水下ULWBRCC最早的水化过程，预测的后期水化模式与实验结果吻合；水下环境优化了ULWBRCC的水化过程，使其早期抗压强度提高19.6%。本文采用时间序列模型对ULWBRCC水化进行预测，填补了水下快速修复水泥基复合材料早期性能预测的不确定性空白，与其他模型相比，Informer模型的MSE提高了92.88%。

期刊介绍： The Journal of the American Ceramic Society contains records of original research that provide insight into or describe the science of ceramic and glass materials and composites based on ceramics and glasses. These papers include reports on discovery, characterization, and analysis of new inorganic, non-metallic materials; synthesis methods; phase relationships; processing approaches; microstructure-property relationships; and functionalities. Of great interest are works that support understanding founded on fundamental principles using experimental, theoretical, or computational methods or combinations of those approaches. All the published papers must be of enduring value and relevant to the science of ceramics and glasses or composites based on those materials. Papers on fundamental ceramic and glass science are welcome including those in the following areas: Enabling materials for grand challenges[...] Materials design, selection, synthesis and processing methods[...] Characterization of compositions, structures, defects, and properties along with new methods [...] Mechanisms, Theory, Modeling, and Simulation[...] JACerS accepts submissions of full-length Articles reporting original research, in-depth Feature Articles, Reviews of the state-of-the-art with compelling analysis, and Rapid Communications which are short papers with sufficient novelty or impact to justify swift publication.
