Abstract
study the effects of co-melting slags
produced from municipal solid waste
incinerator bottom ash and industrial
calcium fluoride sludge on pozzolanic
reaction and durability in cement-based
composites materials. The results
showed that the lowest pouring
temperature was 1081℃ when the
co-melting ash and sludge were in the
ratio of 7:3. The molten slag was then
water-cooled and examined its
properties. It was observed that the
water-quenched slag was amorphous and
had a specific gravity of 3.15 which was
close to Class C fly ash.
The results of compressive strength,
degree of hydration, MIP and SEM
indicated that the slag was a latent
pozzolans and it could replace 3% to
20% cement in mortar. It was also
observed that 3% replacement of cement
with slag would enhance concrete
properties with denser microstructure
based on resisitivity and RCPT results.
