Annual Report 2003-2004

Chemistry & Materials Research CenterNRIProject Results: During the project, corrosion inhibitors and silica fume with different percentageshave been used in the specimens after manufacturing several samples in Paye BetonCompany and accomplishment necessary tests. Mechanical and corrosion tests carriedout on them.Corrosion and penetration tests are long time period and they should be accomplishedin certain period for example determination of corrosion potential. When specimenswere be corroded (initial and propagation of corrosion), they are be tested inlaboratory. The use of “Corrosion Inhibitor” during the mixing process of concretewas shown to be the most effective method for corrosion prevention in most ofcorrosive areas.Project Documentation:- Nonmetallic Department; Report of “Gathering Information and selection ofsuitable region for installing the specimens”; Chemistry & Materials Research Center;NRI; July 2002.- Nonmetallic Department; Report of “Investigation of corrosion mechanism andprincipal concrete aggregates”; Chemistry & Materials Research Center; NRI; Nov.2002.- Nonmetallic Department; Report of “Investigation of required laboratoryequipments”; Chemistry & Materials Research Center; NRI; Jan. 2003.- Nonmetallic Department; Report of “Making the specimens according to thestandards”; Chemistry & Materials Research Center; NRI; May 2003.- Nonmetallic Department; Report of “Installing the specimens and carrying out therequired tests”; Chemistry & Materials Research Center; NRI; Aug. 2003.- Nonmetallic Department; Instructions to manufacture durable reinforced concretepoles; Chemistry & Materials Research Center; NRI; March 2004.126
