Influence of extraction methods on behavior of Municipal Solid Waste Incineration fly ashes as admixtures in cementitious mortars

Popis výsledku v původním jazyce

Probably the most perspective field of utilization of Municipal Solid Waste Incineration (MSWI) ashes consists in its application as admixtures in cementitious building materials. Bottom ash, due to its wide particle size distribution, is usually intended to be used as aggregate while fly ash can feature pozzolanic properties and thus be used as Supplementary cementitious material (SCM). Unfortunately the raw MSWI fly ash may contain ? in dependence on applied Air Pollution Control (APC) technology ? also environmentally hazardous components (POPs, heavy metals) and salts (chlorides, sulfates). The utilization of fly ash as admixture in fact solves the problems related to POPs and heavy metals due to stabilization and solidification effect but chlorides and sulfates represent problem due to its negative effect on hydration of Portland cement and reactive components of fly ash itself. Hence content of chlorides and sulfates in fly ash has to be reduced in order of its successful applica
