Study on the Durability of Cementless Concrete Produced with Industrial By-Products

Abstract:

This study evaluated the durability of concrete produced with a cementless binding material and potassium hydroxide (KOH) based on ground granulated blast furnace slag and fly ash. These industrial byproducts are used to replace cement in order to reduce carbon dioxide emissions. The test conducted for the freezing and thawing resistance of concrete using cementless binding material revealed that the relative dynamic modulus was 83.4%. From the results of a chemical resistance test, the mass reduction rate stood at 12.3% for the 5% HCl solution and 12.7% for the 5% H₂SO₄ solution, showing better chemical resistance than concrete using cement. The depth of neutralization was observed to be 4.48mm, a similar level to that of cement-containing concrete.
