Does concrete corrode aluminum ?
Does concrete corrode aluminum ?
(OP)
Hello dear engtip members. This is my first post into this discussion board.
I am currently working in a aluminum extrusion company.
Last week my manager, proposed a project that is construction of sun-shields for our parking lot of the factory.
The construction will be made out of aluminum.
I am thinking the use aluminum profiles to construct that.
First I will dig the ground and then land the aluminum profile in some depth with concrete.
But I wonder If is there any chemical attack would occur from concrete to aluminum?
Or
What happens if I use steel rods for reinforcement of profiles ?
Thanks

At my situation, aluminum bars will be in touch with fresh concrete till the concrete becomes dry. Well, after the concrete becomes dry the aluminum bar would be embedded into it of course. I wonder, in this case, long term contact with concrete would cause any adverse effect on aluminum ?

If you go with steel for this you also need to be careful. The steel in the concrete will be fine, but where the steel and Al meet there is also a chance for corrosion. Normally there are isolation kits used (washers and bushings) to prevent the two metals from touching.
