CSEB and CUSEB in fiber woven earth

This database is a systematic collection of experimental data on fiber-modified Compressed Stabilized Earth Blocks (CSEB) and Compressed Unstabilized Earth Blocks (CUSEB). Comprising 18 structured Excel appendices, it covers the full lifecycle of earth block research—from material formulation and preparation parameters to performance characterization—serving as a valuable resource for researchers, engineers, and practitioners in sustainable construction, earth materials science, and green building technology.
The database is divided into two core material systems: CUSEB (7 appendices) and CSEB (10 appendices), plus one appendix on fiber types. The CUSEB dataset includes basic material properties (20 entries), soil properties and preparation parameters (14 sets), and key performance metrics: water absorption (5 records), bulk density (8 data points), thermal properties (18 entries), compressive strength (72 results), and flexural strength (40 records). This enables detailed analysis of how fiber modification affects the physical, mechanical, and thermal behavior of unstabilized earth blocks.
As the larger component, the CSEB dataset offers more extensive data: basic information (38 entries), soil properties and preparation parameters (35 sets), water absorption (17 records), bulk density (15 data points), and thermal properties (115 entries). A key feature is its detailed compressive strength data, split into three categories—cement-stabilized (146 entries), lime-stabilized (60 entries), other stabilizers (29 entries)—plus a general dataset (223 entries). It also includes 87 flexural strength records, providing a complete mechanical profile.
Supplementing both systems is an appendix documenting 14 fiber types, providing context on fiber materials and enabling comparative analysis of fiber effectiveness. Across all appendices, the database uses consistent structuring with clearly labeled columns (fiber type, stabilizer dosage, curing conditions, performance results), ensuring easy data retrieval and analysis.
This database fills a key gap in existing literature with a centralized, structured collection of fiber-modified earth block data. It supports diverse research applications: developing predictive models, optimizing fiber-stabilizer combinations, comparing CSEB vs. CUSEB performance, and formulating best practices for sustainable earth construction. Its comprehensiveness makes it valuable for academic research, industry product development, and green building policy.

本数据库为纤维改性压实稳定土砖（Compressed Stabilized Earth Blocks，CSEB）与压实非稳定土砖（Compressed Unstabilized Earth Blocks，CUSEB）的系统性实验数据集合集。本数据库包含18个结构化Excel附录，覆盖土砖研究的全流程——从材料配方、制备参数到性能表征，可为可持续建筑、土材料科学及绿色建筑技术领域的科研人员、工程师与从业者提供极具价值的参考资源。

本数据库分为两大核心材料体系：压实非稳定土砖（7个附录）与压实稳定土砖（10个附录），外加1个关于纤维类型的附录。其中压实非稳定土砖数据集包含基础材料特性（20条条目）、土体特性与制备参数（14组数据），以及核心性能指标：吸水率（5条记录）、体积密度（8个数据点）、热学特性（18条条目）、抗压强度（72组结果）与抗弯强度（40条记录），可用于细致分析纤维改性对非稳定土砖物理、力学与热学性能的影响。

作为体量更大的分支，压实稳定土砖数据集包含更丰富的内容：基础信息（38条条目）、土体特性与制备参数（35组数据）、吸水率（17条记录）、体积密度（15个数据点）与热学特性（115条条目）。其核心特色之一为详尽的抗压强度数据，分为三类：水泥稳定组（146条条目）、石灰稳定组（60条条目）及其他稳定剂组（29条条目），另包含通用数据集（223条条目）；同时包含87条抗弯强度记录，可完整呈现其力学性能全貌。

另有1个附录对两类体系进行补充，该附录记录了14种纤维类型，可为纤维材料的相关研究提供背景支撑，并支持纤维改性效果的对比分析。所有附录均采用统一的结构化格式，列标签清晰明确（纤维类型、稳定剂掺量、养护条件、性能结果），便于数据检索与分析。

本数据库通过集中化、结构化的纤维改性土砖数据集集合，填补了现有文献中的关键空白。其可支撑多类研究应用：开发预测模型、优化纤维-稳定剂复配方案、对比压实稳定土砖与非稳定土砖的性能差异，以及制定可持续土结构施工的最佳实践规范。该数据集的全面性使其可广泛服务于学术研究、工业产品开发与绿色建筑政策制定等场景。
