Özet

The aim of this work is to investigate how the replacement of by-products such as bottom ash (BA) or granulated blast-furnace slag (GBFS) as fine aggregate in concrete affects the chloride permeability of concrete. And so to have an opinion about the effect on the corrosion risk in reinforced concrete. Thus, rapid chloride permeability test and capillarity tests are conducted on the GBFS and BA concretes by replacing 10, 20, 30, 40 and 50% of fine aggregate by weight. Recently, there are researches related with replacement of aggregate as non-ground form of GBFS and/or BA. GBFS and BA can be substituted as fine aggregate in concrete production because of their positive effects on concrete durability. Three different groups of concrete are produced by replacing GBFS and BA single or mutual. Test results show that these types of concretes have sufficient durability for the structures exposed to chloride ion penetration.
