Technical feasibility and life cycle assessment of an industrial waste as stabilizing product for unpaved roads, and influence of packaging.

The use of industrial solid wastes with a high content of SiO and AlO, called "precursors", is often studied in the construction industry when combined with NaOH as "activator". The precursor and activator system is generally proposed as a binder material with similar characteristics to Portland cement. In this work, we technically and environmentally evaluated such a system elaborated with an industrial waste: coal ash with caustic soda in solid state.
