now, development of water area environments has placed
an emphasis on flood control and irrigation. However, in
the future, consideration of the natural ecosystem through
technological advances in the rehabilitation of water area
environments will become an important task. One solution
for the task comes from environment-friendly concrete,
so-called eco-concrete, which can reduce the environmental
load and contribute to the harmonious coexistence of
humankind and nature [4]. Eco-concretes can be classified
based on their usage as environmental load reducing types
and bio-responsive types, which are subdivided into
concrete for microbial attachment and concrete for water
purification [5].
