CEE300/TAM324 HW29 Use an internet search to find information about design of reinforced concrete structures. Answer the following questions: a) What factors affect the location of rebar in Reinforced Concrete structures? Different factors affect the location of rebar in reinforced concrete structures such as: the strength required by the concrete, the shape of the structure, the type of strength (tensile or compressive) required in the structure, and lastly the active corrosion period and the type of rebar being used. b) How much concrete cover (the layer thickness between rebar and exterior surface) is

Unformatted text preview: typical? In the US, the concrete cover is usually between 40-50 mm thick. c) Is epoxy coa±ng on rebar a “perFect solu±on” For corrosion problems? IF not, what kind oF limita±ons does it have? It’s not the perFect solu±on. Some limita±ons are that epoxy-coa±ng increases costs For produc±on oF reinForcement. Epoxy coa±ngs become bri³le and delaminate From the steel reinForcement iF exposed to high chloride concentra±ons. Also, how good the epoxy coa±ng is applied. Poorly adhering epoxy coa±ngs have actually increased corrosion problems....

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
