Abstract:
In order to study anti-corrosion performance of concrete in saline soil region,a visit was paid to Chaerhan salt lake saline soil region in Geermu, Qinghai Province. Authors researched the corrosion situation of concrete structures and members in saline soil region, collected several effective saline corrosion measures of concrete, analyzed saline corrosion measures and prevention effect, summarized the corresponding effective and feasible anti-corrosion measures for different engineering structures. Results show that the engineering structures contacted with saline soil or salty water are corroded most serious, concrete structures and members of taking anti-corrosion measures have less corrosion, improving the strength grade of concrete and increasing the protective layer thickness can suit for all kinds of concrete structures' anti-corrosion. The study results can provide references for newly built concrete structures and members' anti-corrosion.
