Corrosion Behavior Of Reinforcing Steel In Concrete, Rong Du, Gui Gui, Rong Hu, Feng Zu Gang, Tan Jian De, Lin Chang Guang, Jian Jian

Journal of Electrochemistry

The corrosion behavior of reinforcing steel in concrete in chloride free and chloride contaminated simulated concrete solutions was studied by electrochemical technique.The results showed that the reinforcing steel exhitibted different corrosion characteristics in the different solutons.In general ,the steel in concrete was protected in the test solutions with no salt or the lower concentration of NaCl.When the concentration of NaCl is larger than 70%,however,the corrosion behavior of the steel varied considerably,and the corrosion rate increased as pH fell and the concentration of Cl - increased.

Gfrp Reinforced Concrete Bridge Decks (Kyspr 96-169), David Deitz, Issam E. Harik, Hans Gesund Jul 2000

Gfrp Reinforced Concrete Bridge Decks (Kyspr 96-169), David Deitz, Issam E. Harik, Hans Gesund

Kentucky Transportation Center Research Report

This report investigates the application of glass fiber reinforced polymer (GFRP) rebars in concrete bridge decks as a potential replacement or supplement to conventional steel rebars. Tests were conducted to determine the material properties of the GFRP reinforcement, and experiments were performed to study aspects of GFRP rebar placement in actual bridge decks. These included observation of GFRP rebar handling characteristics and worker response during construction. Load tests of full-scale reinforced concrete specimens were conducted to evaluate the characteristics of three reinforcing schemes: (1) an epoxy coated steel (ECS) reinforcing scheme; (2) a GFRP reinforcing scheme, and (3) a Hybrid …

A new Zn-Ni-Cd plating process was developed which offers a unique way of controlling and optimizing the Ni and Cd contents in the final deposit. Zinc-nickel-cadmium alloy was deposited from a 0.5 M NiSO4 + 0.2 M ZnSO4 bath in the presence of 0.015 M CdSO4 and 1 g/L nonyl phenyl polyethylene oxide. Using this process a Zn-Ni-Cd ternary alloy, with a higher nickel content as compared to that obtained from conventional Zn-Ni baths, was synthesized. The Zn-Ni-Cd alloy coatings deposited from an electrolyte containing 0.015 M (0.3%) CdSO4 has a Zn to Ni ratio of …
