This thesis investigates how locally excavated soil from Rotterdam could be translated into reproducible unstabilised compressed earth blocks rather than remaining within low-value fill or disposal pathways. Instead of treating production as a universal recipe, it examines how the behaviour and characterisation of a local soil inform its processing, mix composition and assessment. To address this, the study combines a literature review with laboratory testing. The experimental work included geotechnical identification, particle-size analysis, mineralogical and environmental assessment, followed by specimen production, compaction trials, and compressive-strength testing.
On this basis, controlled mixtures were developed to investigate workability, optimise composition and evaluate the influence of key parameters such as compaction moisture, particle-size distribution and press loads. The study establishes the general suitability of the excavated soil, while identifying main limitations, processing constraints, and the governing parameters for mechanical performance.
