I bought a lab-grade Hygrometer to monitor fungus/molds growth in my optical lens.. and as I got familiarized about humidity and water vapor and how there is constant water vapor in the air at all times even in the middle of Sahara dessert.. then I got curious how this interacts with rebars...
Age of the structure is 3 years... at midspan there are flexural cracks. Well.. for any structure and with flexural cracks at midspan.. if rusts develop.. it's like the bars are cut in half and the beam would collapse.. doesn't this occur for those old buildings that are decades old?
Anyway. Do...
I live in a country where such 2 component resin are non-existant and we have to import the technology.. but first I need to know first the dynamics of rust formations in the rebars.. how fast do rebars corrode inside concrete with a crack opening? Remember there are many tension cracks in old...
I'm just asking if the rebars will corrode inside (note: not the concrete corroding) if there is any crack width of any size (assuming it's not exposed to the weather or not exposed to any water source).. and how do you fill up the crack say tension cracks?
Oh.. our senior structural engineer has only seen it.. it's tension cracks.. so in any tension cracks where rebars are exposed (even how tiny).. can it get rusted?
Hi,
If there is a small crack in the concrete with rebars exposed inside.. and supposed it is not exposed to water.. can the natural moister from humidity corrode the rebars? how many percentage relative humidity before any rusts can start to occur and how long before that can happen?
If...
