Different Damaged Shaft Lining Concrete Resistance to Sulfate Corrosion
|Published in:||The Open Construction and Building Technology Journal, December 2014, n. 1, v. 8|
Shaft lining concrete itself has a certain degree of initial damage before being corroded by sulfate. In order to study the resistance of the concrete of the initial damage in different corrosion solution concentration of sulfate, samples of concrete without initial damage, loaded 50% ultimate load and loaded 70% ultimate load with initial damage concrete were selected and studied their corrosion resistance in 9%, 12% and 15% concentrations of sulfate solution. The results show that compared with concrete with no initial damage, the concrete with initial damage resistance to sulfate corrosion is varied. With the increased concentration of the corrosion solution, the concrete with worse initial damage exhibited much lower resistance to sulfate corrosion.
