The objective of this pilot is to utilize industrial by-products, including granulated slay fly ash, geopolymers, and other suitable materials, to stabilise natural soils. The following steps will be followed:
steps
- • Soil samples will be collected from critical areas, and the laboratory will assess the ability of various candidate by-products to enhance the strength and stiffness of the soil.
- • The selected solution will be implemented and demonstrated at a specific site to showcase its effectiveness and feasibility.
- • The most effective and environmentally sustainable stabilisation solution will be evaluated using a numerical model. This assessment will consider factors such as increased safety levels and the potential impact of subsidence over the entire lifespan of the structure.
“Oostmolendijk”:
The pilot site is “Oostmolendijk”: it is located between the towns of Ridderkerk and Hendrik-Ido-Ambacht, along the river Noord, and belongs to the dike ring IJssel-monde (Speijker 2000). The Dyke structure is a part of the Dike Ring 17.
Problems arose in particular with the dyke improvement in 2013 for the adjacent dyke section. When a reinforced inner berm was worked on to be constructed, a relatively large shear failure of the recently reconstructed section occurred.
