Data underlying publication: "Early-age and long-term deformations in reinforced slag-based alkali activated concrete"

Data to reproduce results reported in "Early-age and long-term deformations in reinforced slag-based alkali activated concrete". The dataset contains raw experimental data from DFOS (.tsv) instrumented on embedded reinforcement bars in reinforced concrete beams, which is used to investigate shrinkage induced steel deformations of a novel concrete type (alkali activated) and compared with a CEMIII/B-based concrete. Plain shrinkage (and weight loss) measurements (.xls) on sealed and unsealed prismatic samples have been performed in parallel. Furthermore, the dataset contains measurements of cubic compressive strength (.xls) and elastic modulus (.xls), following EN-12390 standards. The dataset includes the figures used in the publication (.tiff; .jpg).

本数据集用于复现《早龄期与长期变形：矿渣基碱激活钢筋混凝土》（Early-age and long-term deformations in reinforced slag-based alkali activated concrete）中的研究结果。数据集包含埋设于钢筋混凝土梁内部钢筋上的分布式光纤传感（Distributed Fiber Optic Sensing, DFOS）采集的原始实验数据（.tsv格式），用于探究新型碱激活混凝土（Alkali Activated Concrete）的收缩诱导钢筋变形，并与CEM III/B型水泥基混凝土进行对比。研究同步开展了密封与非密封棱柱体试样的自由收缩（及重量损失）测试（.xls格式）。此外，数据集还包含依据EN-12390标准测得的立方体抗压强度（.xls格式）与弹性模量（.xls格式）数据。本数据集收录了该论文所使用的配图（.tiff；.jpg格式）。
