RECYCLING OF FLY-ASH IN THE CONSOLIDATION OF CLAY SOILS

Fly ash is a waste material, residue of the coal combustion in steam g enerating station. Its valorization in the consolidation of clays as d escribed 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 appear?; 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.
