Abstract:
The effect of geopolymerization on organic soils has not been investigated in the
literature. Therefore, in this study, the mechanical and deformation behaviors of organic
soils activated by alkali activator and fly ash will be investigated. Furthermore, the
effect of fly ashes with various types and physical and chemical properties, supplied
from 6 different thermal power plants, on the geopolymerization process organic soils
were examined. Axial compressive strength tests were conducted on the specimens
prepared at various rates of fly ashes to better understand the improvement in the
mechanical performance of organics soils and the microstructural analysis (XRD, XRF,
SEM-EDX analysis) were performed on the specimens. In addition, the effect of pH,
TDS, salinity and conductivity on the mechanical properties of the samples as a
chemical analysis were evaluated. Experimental study has shown that;
Geopolymerization processes in organic soils are affected by many parameters and have
remarkable differences compared to inorganic soil types. It has been determined that fly
ash types have a significant effect on the geopolymerization of organic soils.
