ABSTRACT
Cracks can occur in mortar during the construction service life, potentially
reducing the overall mechanical performance of construction components. Selfhealing
mortar is a material innovation that is able to repair cracks by the material
itself without requiring additional treatment. The self-healing process can be
optimized by adding certain materials that function as self-healing agents. Some
materials that can be used as self-healing agents include pozzolanic materials from
industrial waste such as glass powder and materials containing high calcium. This
study analyzed the use of glass powder and quicklime as self-healing agents in
mortar by immersion in water. The mortar mixtures used in this study were control
mortar, GP0QL15, GP15QL15, and GP20QL15, with glass powder (GP) and
quicklime (QL) as partial cement replacements. Tests conducted included flow
value, setting time, compressive strength, strength activity index (SAI), ultrasonic
pulse velocity (UPV), porosity, weight change, visual observation, and
microstructural analysis using thermogravimetric analysis (TGA) and Fourier
transform infrared spectroscopy (FTIR). The test specimens were cured in water for
28 days, then initial testing was performed before immersion. The mortar was given
cracks with a width of 0.1–0.3 mm, then tested at immersion ages of 7, 28, and 56
days. The results showed that the use of glass powder and quicklime increased the
flow value and setting time. The control mortar reached the highest compressive
strength (29.20 MPa) at the age of 56 days, but the value decreased from the
previous age. GP15QL15 provided the best performance with an increase in
compressive strength, UPV, weight change, and crack closure up to 100% at the
age of 56 days, accompanied by a more significant decrease in porosity compared
to other mixtures. TGA and FTIR analysis showed the presence of an active
pozzolan reaction that improved the mortar microstructure. The use of glass powder
and quicklime in a balanced ratio can improve the self-healing ability and
microstructural durability of the mortar during the immersion age.
