Recycling of fly ash in the consolidation of clay soils

摘要

Fly ash is a waste material, residue of the coal combustion in steam generating station. Its valorization in the consolidation of clays as described here, has a double advantage: (i) it is a economical solution to consolidate soils; and (ii) it contributes to reduce disposal and environmental problems. It appears that the incorporation of fly ash in the clay material has a beneficial action on mechanical properties of the clay, like the compressibility and the consolidation.
