Description
Summary:A study was made of the viability of burnt biomass residue from a pulp and paper plant applied as a raw material for mortar used in the construction industry. The waste - bottom ash - was incorporated into the mortar as a mineral addition to the Portland cement. The effect of the grain size of the waste on the properties of mortars containing 10 vol% of waste was investigated, as well as the effect of the concentration of waste with grain size under 0.15 mm. The samples were evaluated after 28 days of ageing by uniaxial compression, leaching test and SEM. These characterisation techniques indicated that the properties of the mortars depend on the concentration, granulation and size distribution of the waste in the structure of the mortar. Some chemical elements may have been present in stabilised and/or encapsulated form in the cement matrix. 10 refs.
