This study aims to optimize the composition of a new ecological concrete made from upgraded excavated soil blends. The novelty of this research lies in the fact that earth-based concrete is cast using classical vibration methods, like ordinary concrete. Several soil-concrete mixtures were tested, composed of varying proportions of clayey soil, sandy soil, and small amounts of cement, jute fiber, and lime. Given the significant volumetric changes that can lead to water infiltration and impact the durability of this material, an experimental investigation on autogenous and drying shrinkage was carried out. Additionally, water porosity and water absorption tests were conducted along with compression strength tests to evaluate the transport properties of this porous material. The findings of this study demonstrate the capacity of using upgraded excavated soil blends to develop a more sustainable and ecologically friendly concrete material, with promising mechanical and physical properties.
