Rendering mortars were prepared by replacing conventional sands, namely coarse sand (CS) and fine sand (FS), by different dosages of biomass dry bottom ash (BA) and fly ash (FA). Bottom ash was treated by sieving and washing and called treated bottom

Alkali-activated materials are generally considered a more sustainable alternative to Portland cement binders. This derives not only from the use of solid wastes as precursors, but also from the low temperatures required for their synthesis. However,

In this work, alkali-activated fly ash-derived foams were produced at room temperature by direct foaming using aluminum powder. The 1 cm3 foams (cubes) were then evaluated as adsorbents to extract heavy metals from aqueous solutions. The foams’ sel

Calcareous sludge is an alkaline waste produced by the paper pulp industry that is commonly disposed of in land-fill. However, recent studies and the European regulations discourage such practice. This work investigates an alternative and innovative

Concretes intended for printing need specific rheological properties that are not found in traditional ones. Printable concretes must have as much consistency as possible and, at the same time, still need to be pumpable. Although the use of chemical
