Abstract
ABSTRACT
In terms of the importance of enhancing concrete coastal structures exposed to chlorides,
this study was initiated with the objective of increasing their lifespan. Two measures
were proposed (i.e. to increase the thickness of the concrete cover oradd Carbon Fiber
Reinforced Polymer (CFRB) sheets).27 R.C. specimens were investigated
experimentally. The specimens were exposed to variable sodium chlorideratios by weight
“salt cement ratio”(s/c) (i.e. 3:100 “3%”, 3:50 “6%” and 1:10 “10%”). The specimens
were prepared, cured, dried and tested. The Zagazig Structural Laboratory was set.
Measuring devices were fixed and measurements were undertaken. Also, photos were
captured and observations were documented. The strains, cracking load and cracking
pattern were determined.The undertaken measurements, the shot photos and documented
observations were analyzed; graphs relating the different parameters were plotted and
were presented. It was found that these enhancement measures improved the behavior of
the concrete specimens subjected to Chlorides which would most probably extend the
lifespan of concrete coastal structures.
