fa گروه سرامیک Ceramic Materials and Engineering Research Paper Research Paper A large number of reinforced concrete structures subjected to chloride ions. Two basicapproaches for preventing corrosion of reinforcing steel embedded in concrete are: Increasing theconsolidation of concrete and using different coating on rebars. In present research steel rebarsare coated in different ways: a) 40 µm of zinc electroplated on steel rebar b) Zinc powder withepoxy paste (zinc rich). The rebars were placed in a macrocell design according to ASTM G109-92. Concrete operations were done with mixture designs of high and normal strength concrete.The results show corrosion decrease of zinc coated rebars. High strength concrete, Normal strength concrete, Rebar corrosion, Zinc coating. 9 15 http://ijmse.iust.ac.ir/browse.php?a_code=A-10-1-5&slc_lang=fa&sid=1 KARAMINEZHAAD M. 1800319475328460018 1800319475328460018 Yes MAGHSOUDI A.A. 1800319475328460019 1800319475328460019 No NOZHATI R. 1800319475328460020 1800319475328460020 No SAKHAEI A. 1800319475328460021 1800319475328460021 No
