A Teacher from Building and Construction Engineering Department obtain a patent about Production of Steel Reinforcement against Corrosion by Coating with Pressurized Rubber

The head of Roads and Bridges Engineering Branch in Building and Construction Engineering Department at the University of Technology Prof. Dr. Mohammad Yousif Fattah gained patented about his research entitled
"PROTECTION OF STEEL REINFORCEMENT AGAINST CORROSION BY COATING WITH PRESSURIZED RUBBER"
And this research was in conjunction with teachers: Lect.Dr Mustafa Ahmed Yousif, lect. Shayma Khalid, and they are from the Civil Engineering Department at the University of Mustansiriya.
The researcher Prof. Dr. Mohammad Yousif Fattah showed coating rebar rod is one of the solutions to overcome the corrosion problem. Many materials for coating are used including epoxy, gallons materials and others which proved their effective despite of some problems, but these materials are not economical due to the cost of materials and the cost of the coat working, that its whole coast can be reached to 50% of rebar cost.
In this study it is applied a new way of coating rebar rubber after exposing it to high temperatures in a metal mold and exposing it to high pressure up to about (200-220) atmospheric pressure so that we can get a rebar coated with rubber has the same original rod shape but a diameter larger. It has been found that the rate of used rubber corrosion material when it placed in a saline concentrated solution of salt (Na2SO4) under the American standard (ASTM G 109) for a period of 21 days is (0.000104) mm / day, equivalent to (0.038) mm / year and is a small number and acceptable in direct exposure conditions so the material can be considered suitable durability.
The test drag results proved on the production that the coated rebar rods with rubber does not fail in its coated part which indicates that this part has become stronger than the rest of the parts, and that the yield stress and fatigue failure of iron rubber-coated was higher in (13-14%) value of the coated iron which denotes getting the second benefit of coating which is increasing the iron resistance.
The coating rebar with rubber way considered economical and easy due to the low cost, compared with the common ways to protect the rebar like gallons or epoxy coating and others. So it is recommended to use this way especially in high-exposure areas of salts and moisture.
