Slag from Biomass Combustion (BCS)—chemical properties in accordance with BCS utilization in cement concrete

Waste from Biomass Combustion - Lightweight Aggregate

“…The problem of using this waste in the building industry is it chemical composition. From the results of previous works [3,4] we can assume that this waste cannot be used neither as a coarse aggregate nor as a binder due to the high amount of amorphous SiO 2 and potassium cations which in the alkaline Ca 2+ solution create new C-S-H formations in high amount. One of the possibilities of solving this problem is use of this slag in the form of sintered lightweight aggregate.…”
