dc.description.abstract | In recent years, kaolinite-based wastes are focusing the attention
of researchers to obtain recycled metakaolinite, with consequent
environmental and socioeconomic benefits. One of
these lines of research is based on coal mining waste, which
once activated thermally, it becomes a highly pozzolanic product
(ACM). This study reports the influence of activated carbon
mining waste on the formation and evolution of the
mineralogical phases in the ACM/cement system as well as
their influence on the microstructure up to 90 d of reaction.
Mineralogical analyses clearly show that the addition of ACM
modified mineralogical compounds of blended cements. The
C4AH13 and C4A CH12 were the predominant phases in this
type of cements; while in the ordinary portland cement
cements, portlandite, ettringite, and carboaluminate were main
hydrated phases. Two differential zones in the pore size distribution
of the C–S–H gels at 12 and 4.5 nm were observed, predominating
the formation of C–S–H gels at 12 nm when 20%
of ACM was added to the cement. | en |
