Özet

Studied in this paper is the effect of SO2 as a pollutant gas on concrete and reinforced concrete specimens at various relative humidity (RH) rates prepared with ideal mixing water (IMW) and IMW + 80 mg NH4+ (NH4Cl) mixing water. The potential values of reinforcing steel were measured throughout 28 days and compressive strength values of concrete specimens in the same medium were determined at the end of the 28th day. SO2 gas was observed to have a harmful effect at higher RHs on compressive strength of concrete and to make more negative the potential values of reinforcing steel. © 2002 Elsevier Science Ltd.
