| 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. | ||
