Experimental Research On Corrosion Mechanics Of Modified Concrete In Dirty Water

In the city environment engineering, the construct which dirty water are transported and disposed with generally are made up with concrete. The concrete of the sewage disposal system be corroded by various corrosion contaminant, which caused the structural strength descend; which made it is impossible to attain the request of term of service, which meanings need more resource and energy.This paper studied the experimentation that dirty water corroded concrete, referring to the research result of dirty water corrosion. The tests phenomena had been observed. The tests result had been analyzed. Modified concrete resistance mechanism had been probed into. The results show that: modified concretes have stronger corrosion resistance than normal concretes. The corrosion mechanism of dirty water is complex, the action of various corrosion contaminant make up it.This paper was carried out that the experimental tests of concrete, which specimens were respectively immersed in two buffer solutions, citric acid and vitriol, referring to the research result of dirty water corrosion and the analysis of dirty water component. The tests phenomena had been observed, the tests result had been analyzed, modified concrete resistance mechanism had been probed into. The results show that: modified concretes have stronger corrosion resistance than normal concretes, simultaneity; the citric acid has more intensive corrosion to concrete than the vitriol at same PH volume.
