Currently, a soil stabilization approach using fly ash as an effective choice for increasing
soil stiffness and strength has emerged. With the presence of water, the lime in the fly ash would
be separated, generating cementitious materials binding the grains of sand. In the present study,
the influence of curing time and saturation during specimen preparation on the behavior of fly ashmodified
sand was observed by performing a series of splitting tensile strength tests. It was found
that the splitting tensile strength increases with fly ash content and curing time and decreases with
saturation. The splitting tensile strength produced at 30% saturation was approximately two-fold
higher than 100%, particularly at one month of curing time. However, the splitting tensile strength
at higher saturations approaches lower, especially at longer curing times. Porewater evaporation
accelerates the self-hardening occurring over time during curing. By increasing the fly ash percentage
from 5% to 20% in the mixture, the splitting tensile strength increased by up to twenty-fold in the
present study. An equation has been proposed as a function of porosity/volumetric fly ash content,
curing time, and saturation during the preparation of the specimen.
Keywords: fly ash percentage; curing time; saturation; fly ash-modified sand; splitting tensile strength
