Abstract :
Enhanced durability of concrete plays a
crucial role in the serviceability of structures in marine
environments. In this study, performance of self
compacting concrete (SCC) blended with Fly Ash (FA)
and Silica Fume (SF) in the form of binary and ternary
mixtures in the simulated marine environment is
investigated. This study aimed at utilization of high
volumes of FA, up to 60% replacement of Ordinary
Portland Cement (OPC), for development of sustainable
and durable SCC located in marine environment. SCC
was examined for fresh as well as hardened state
characteristics like flowability, compressive strength,
split tensile strength and durability characteristics such
as sorptivity and chloride ion penetration resistance. The
results showed that SCC can be prepared with FA and
SF up to 40% and 10% replacement of OPC
respectively. There was a remarkable improvement in
the durability performance of SCC in ternary mixtures
containing 30% FA and 10% SF. At later ages, SCC in
ternary mixtures showed improved strength in marine
environment.The experimental investigation indicated
improved performance of high-volume FA based SCC in
marine environments.
