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.
