ABSTRACT = {Durability and ecological effects of the stainless steel reinforced coral
waste concrete were compared with those of the carbon steel reinforced ordinary
concrete. The results showed that the corrosion current densities of the stainless
steel in the coral waste concrete were less than one-tenth of those of the carbon steel
in the same grade ordinary concrete. The stainless steel in the seawater coral waste
concrete maintained passivation even after more than two years of immersion in
3.5% NaCl solution, while the carbon steel counterparts in the ordinary concrete
were seriously corroded under the same condition. Simultaneously, the corrosion
current density of the stainless steel reinforcement decreased slightly with the
strength grade of the coral waste concrete. The ecological evaluation indicated that
the non-renewable energy consumption and CO<sub>2</sub> emission of per cubic meter of the
newly constructed stainless steel reinforced coral waste concrete were 23.72% and
1.419% less than those of the carbon steel reinforced ordinary concrete with the
same grade, while the aforementioned two parameters of the former material were
reduced by 44.81% and 32.0% in comparison to the latter one in 50 years duration.},
